Reducing income inequality is one of the goals under the Sustainable Development Goals. This study examines the intricate relationship between financial development, policy uncertainty, inflation, and income inequality. Panel data for African countries covering the period 2000-2022 were used in the analysis. The study used the economic policy uncertainty (EPU) index to examine its effects on income distribution. Previous studies indicated the possibility of asymmetric effects of inflation and EPU on income inequality. Hence, a dynamic non-linear Panel ARDL was employed to examine the asymmetric nature of the relationship between these variables. The study found that in the long run a symmetric EPU reduces income inequality for the countries in the study and this is confirmed by the asymmetric negative EPU that had a negative and significant impact on inequality. Income equality was found to deteriorate with an increase in inflation. Moreover, inequality was found to be more sensitive to negative changes in inflation relative to a positive change as inequality's elasticity to positive change was much lower as compared to negative changes. Under certain conditions and economic context, redistributive policies can alleviate inequality during a period of heightened EPU. By examining the theoretical frameworks and empirical evidence, the study highlights that for the countries in this study, policy uncertainty reduces inequality. Also, countries should continue with inflation targeting policies and if possible, aim for a lower rate relative to the previous period.

This article investigates the relationship between environmentally related taxes introduced in OECD countries and air pollution, represented by carbon dioxide and greenhouse gas emission levels in the atmosphere. The article makes a statistical analysis of data on environmental taxes, specifically energy and transport taxes, and other variables that might affect air quality in the OECD member countries. The ARDL model used on the panel data of all OECD member countries shows statistical significance in only one out of five models. A subsequent comparative analysis of the reduced sample of OECD countries that are members of the EU exhibits a statistically significant effect of environmentally related tax revenues on the air emission levels, indicating that this relationship is present in the reduced sample.

This paper provides empirical evidence in support of the view that quality of institutions is an important determinant of medium and long-term growth in OECD countries. Regarding the methodology, a panel data analysis with two-stage least squares (2SLS) estimation will be used to account for the endogeneity of the institutional variable. Besides institutional quality, we also consider other relevant determinants of potential growth such as the initial level of GDP per capita, public debt, and structural variables typically referred to in economic growth theory. Our estimation results show a positive impact of institutions on subsequent economic growth: an increase in 1 point in institutional quality leads to an estimated increase of 16.88 percentage points in potential GDP per capita growth, in the case of high-debt countries. With this, we notice a particular rel- evance of institutions in countries with high levels of debt. Therefore, our findings support the necessary attention to the institutional tissue of societies since improvements in institutional quality can subsequently improve economic growth.

Mancur Olson wrote his influential study Big Bills Left on the Sidewalk: Why Some Countries are Rich, and Others Poor in 1996. In his paper, Olson claimed that the differ-ences in economic development between countries are caused by only two factors: institutions and policies on the one hand and culture on the other. We attempt to test his conjecture using econometric modelling, combining and comparing it with a broadly defined orthodox production function in an indirect neoclassical notation (Solow-Minhas-Arrow-Chenery's SMAC framework). The "pseudo-production function" obtained is econometrically sound and of explanatory power similar to models including economic variables, although we find strong evidence of interdependence between capital-labour share and institutions and policies and culture. We consider the test, performed on panel data from 154 countries over five-year averages from 1980-2014, to be robust and consistent with Olson's ideas.

This paper contributes to the current literature dealing with drivers of bank business model changes. We analyse the relationship between fee and commission income share and banks' performance in terms of profitability, risk and risk-adjusted profitability in the European Union. We applied the System Generalized Method of Moments to a unique data set of 329 EU banks in the period 2005-2014, which resulted in three key findings. First, we did not find any diversification benefits by increasing the fee income share. Therefore, we can conclude that the increase in fee income share observed in recent years in EU banks was driven mainly by external factors, such as increased competition, rather than by internal reasons. Second, higher reliance on equity financing and better quality of provided loans enhance banks' performance. Third, bank business strategies and macroeconomic factors are crucial determinants of banks' performance.

Interest rates in many advanced countries have reached zero lower bound and this has led to the widespread use of unconventional monetary policies after the global crisis. Hence, it has been more and more important to better understand the effects of these policies on major economic variables and the transmission mechanism through which they influence the economy. This study analyses the impact of quantitative easing (QE) policies on local currency government bond yield in emerging market (EM) economies in a heterogeneous panel setting. An Augmented Mean Group (AMG) estimator is used that allows for cross-sectional dependence and heterogeneous slopes. Model results show that government bond interest rates in EM economies are determined by country-specific factors such as central bank policy rate, inflation and budget deficit as well as external global factors such as US ten-year government bond yield and QE policies of advanced countries' central banks.

This paper investigates the impact of behavioural attention on the households' foreign currency savings as a response to the external macroeconomic shocks. The information that the households acquire via different communication channels is expected to influence their decisions regarding their savings' allocation into different currencies. This study has applied the fundamental macroeconomic models by including individuals' attention to the specific risks and search interest in specific keywords on Google in order to assess the impact of acquired information and its communication channel on the households' foreign currency savings. We employed a two-level mixed effects model including macroeconomic fundamentals and individuals' attention to the information determinants. We solved a problem of a long list of potential explanatory variables (keywords) by employing the Bayesian Model Averaging. This study assumes that households are more sensitive to the macroeconomic shocks (factors) if they search simultaneously for infor-mation on Google about these factors or specific related risks. The results emphasize the role behavioural attention during financial turmoil and economic downturn periods, especially in the environment of very low interest rates.

This paper empirically assesses the financial performance of Czech credit unions in relation to other European cooperative banks in terms of their profitability and stability. We created a unique dataset of 283 cooperative banks from 15 European countries in the period 2006-2013. Using the system GMM and alternative panel data methods, we reveal worse performance of Czech credit unions in terms of both profitability and stability compared to their European peers. We also argue that big credit unions in the Czech Republic have assumed a non-sustainable business model depending on excessive risk taking while enjoying implicit subsidy via deposit insurance. In conclusion, we argue that under recent capital management policies, big Czech credit unions will likely face serious financial problems in coming years.

This paper investigates the short and long-run relationship between credit risk and two bank profitability indicators ROA and ROE in Central and Eastern European countries during the period from 2000 to 2010. Results from previous research mostly confirm the negative relationship between profitability and credit risk by considering the current or one year lagged value of profitability. Certain crisis indicates that more profitable banks before the crisis became more risky during the time of crisis. These results motivate us to upgrade the model of credit risk by including earlier values of profitability. Results indicate that two or three years are necessary for growth of profitability to increase credit risk. However, the long-run relationship between foreign banks' profitability and credit risk is positive, for both indicators. For the domestic bank, the long-run effect of ROA on credit risk is positive, while for ROE this relationship is negative.

This paper seeks to investigate the effect of financial development on growth in OECD countries during 1999–2014. The aim of the analysis is to study the dependence of growth on given financial development indicators along quantiles of the conditional growth distribution, taking into account the effect played by each country over time. For the purpose of the empirical analysis, it performed the instrumental variable quantile regression panel data (IV-QRPD) model suggested by Powell (2016). The findings of IV-QRPD model indicated that the effect of finance on growth is changing along quantiles of the conditional growth distribution. That is to say, we provide some evidence that high-growth OECD countries react to the changes in financial development less than low-growth countries.

This paper aims to theoretically derive and afterwards econometrically assess the impact of intellectual property protection (IPP) on national economies. The authors’ main hypothesis is that by creating a form of non-market protection, IPP limits free competition and has no positive effects on national economies and the world economy in general. The hypothesis is tested through estimation of relationship between charges for the use of intellectual property and 1) gross domestic product, 2) GDP growth, 3) unemployment, 4) exports of high-tech products, 5) FDI outflow, and 6) expenses on research and development in a panel dataset of 146 countries in years 2005–2014 based Arellano-Bond estimator for dynamic panel models. The data tells us that changes in these charges have not a significant impact on the studied indicators, which counts against claims of positive impact of IPP on economies and growth.

In this paper, we analyse the key determinants of bank fee and commission income in the European Union with a special emphasis on market concentration. On a sample of 258 EU banks during the 2007–2014 period, we apply System Generalized Method of Moments. First, we argue that the banks facing higher competition tend to expand more aggressively into non-traditional activities, and therefore they report a higher share of fee income in total income. Second, we found that a higher equity to assets ratio is related with higher shares of fee income since the bank needs more capital to prevent or manage the potential risks of the non-traditional activities. Finally, a high deposits to assets ratio tends to increase the fee income share, which may be possibly attributed to relatively high switching costs and to close depositor-bank relationship in the EU banks.

Estimation of claims reserves, which should be held by the insurer so as to be able to meet expected future claims arising from policies currently in force and policies written in the past, presents an important task for insurance companies to predict their liabilities. A common approach to the reser-ving problem is based on generalized linear models (GLM). In this article, the application of genera-lized linear mixed models (GLMM) - an extension of the GLM - for estimation of the loss reserves is shown. Since the GLMM allows incorporating a random effect instead of several fixed effects corresponding to the accident years as in case of the GLM, volatility of the prediction is reduced. This allows more flexible risk valuation, which is a crucial element of risk management and capital allocation practices of non-life insurers. A real data example together with diagnostics for the model selection are provided as an illustration of the potential benefits of the presented approach.

The paper examines determinants of sovereign bond spreads (in relation to Germany) of the peripheral euro area countries in the period 2007Q3-2015Q3. The study indicates that the introduction of the Outright Monetary Transactions (OMTs) by the ECB in the third quarter of 2012 led to a change in the sensitivity of the spreads to the developments of certain macroeconomic fundamentals of these economies. In particular, the ratio of public debt to GDP, which significantly and strongly determined the spreads in the period 2007Q3-2012Q2, proved to be insignificant in the period 2012Q3-2015Q3. In addition, the counterfactual analysis carried out shows that the spreads in the analysed countries would have been much higher if the ECB had not decided to introduce this programme.

The main objective of this paper is to find the determinants of the international competitiveness of the manufacturing sectors of the Czech economy, using the database of 13 manufacturing sub-sectors in 1995-2011, with the aid of ECM model. The authors research the question of how much foreign and domestic demand, the level of labour costs, the level of sector innovation intensity, the level of sector openness to foreign markets as well as sectoral labour productivity influence the changes in their trade balance. The results of the analysis conducted show substantial differences in the roles particular variables play in explaining the net exports in individual sectors. The results of the analysis indicate mostly a greater impact of the researched factors on net exports in long rather than short term.

The effects of the financial crisis, that started in 2008 and first emerged on the American housing market, have been experienced by many European economies. The purpose of this article is to attempt to measure and assess the sensitivity of convergence processes to crisis in European Union's regional economies taking into consideration their sectoral structure. Particular resistance to crisis is associated with the presence of "modern" sectors of the economy. The study covers the panel of the European Union NUTS-2 level regions in the period 2005-2011. In the analysis, the application of panel data allows for inclusion of the specific non-measurable aspects characteristic for particular regions and time.

The paper quantifies the role of factors associated with the growth (or decline) of micro and small businesses in European economies. The growth is related to the levels of employment and value added in enterprises, as well as, ten institutional variables. We test the data for consistency of behavioural patterns in various countries and gradually remove outlying observations that can lead to erroneous conclusions when using the classic estimators; this is a quite unique approach in panel data analysis. In the first part of this paper we outline a highly robust method of estimation based on fixed effects and least trimmed squares (LTS). In its second part we apply this method on the panel data of 28 countries in 2002-2008 testing for the hypothesis that micro and small businesses in Europe use different strategies for their growth. We run a series of econometric tests where we regress employment and total net production in micro and small businesses on three economic factors: gross capital returns, labour cost gaps in small relative to large enterprises and GDP per capita. In addition, we test the role of 10 institutional factors in the growth of family businesses.

Arrangements to cooperate on innovation facilitate access to external sources of knowledge. By using panel data derived from the five waves of Community Innovation Survey in the Czech Republic, we examine whether firms engage in these arrangements persistently or rather revert to other behaviour. Econometric estimates of dynamic random effects and multivariate probit models provide strong support to the thesis of persistence, particularly of linkages with the university sector and suppliers. The results are robust to the initial conditions problem and serial correlation in idiosyncratic errors. Government programmes initiating cooperation on innovation therefore have the potential to induce durable changes in the innovative behaviour of firms.

Wide range of academic studies and economic practice are showing strong correlation between GDP growth and FDI flows. Moreover, there is a number of cases when FDI inflows were positively impacting economic development. That provides grounds and needs for profound research in the area of investment determinants. The main objective of this paper is to classify FDI determinants in the EU countries. All assuming that there are differences between the two groups - old and new member states. The econometrical approach of gravity modelling was chosen as the most appropriate methodology to analyse panel data set. Panel is depicting FDI flows coming from the external nonEU investors and does not include intra EU investment flows among the member countries (firstly due to the relative insignificance of the intra-EU flows compared to the outer inflow values and secondly due to the need to answer what exactly leads non-European investor to opt for the EU country A and not B). The random effect model has proved diversity in FDI flows determinants. Study outcomes support the need for policymakers' attention in the EU investment policy harmonization, towards market equalization that would improve competiveness of the whole EU region.

Foreign direct investment has become an important factor of development of economies in the last decades. However, its economic nature as well as its relationship with corruption has not yet been clarified in economic literature. Following previous theoretical research, mainly Dunning's eclectic model, this paper evaluates the econometric relationship between corruption and foreign direct investment by testing three theoretically-based hypotheses: that corruption perception indicator is a stationary variable, that the relationship between corruption and foreign direct investment stock is statistically weak and that changes in foreign direct investment stock do not Granger cause changes in corruption. The verification is based on unit root tests, panel co-integration and Granger causality models performed on data from the Transparency International, the World Bank and the Heritage Foundation and the UN Conference on Trade and Development (UNCTAD) for 94 countries for the years 1998-2007. The results show that there is no significant relationship between the two variables.

The Kuznets hypothesis of inverted U-curve dependence of the income inequality on the absolute value of the average income is still an unresolved issue despite the growing number of theoretical and empirical research on this topic. This paper analyzes the historical data on the average income and the income inequality for the period 1979-2009 collected for 145 countries. We found that the income inequality is influenced predominantly by governmental policy on subsidies and social transfers. Different amount of subsidies and social transfers across various countries makes the data biased. The inverted U-curve was found in countries with low amount of social contribution. However, increasing amount of social contributions makes the U-curve flat and shifts its maximum to higher values of the average income. Based on the experimental data a model describing the influence of both governmental policy and the level of economic development was developed.

This study empirically attempts to unveil the contradictive findings regarding the relationship between fiscal imbalances and inflation in the context of the latest theoretical indications. The empirical analysis covers the period of 1970 to 2009 and applies dynamic panel techniques in a pool of 52 countries that comprises 19 developed and 33 developing ones. This segmentation is applied to illustrate the groups' specific features and the implications of heterogeneity. The findings provide supportive evidence for developing countries. We also find a significant degree of heterogeneity between the groups and the statistical significance of the relationship between fiscal imbalances and inflation in the case of developed countries cannot be ratified.

The purpose of this paper is to investigate the determinants of labour market dynamics in EU-27 in the recent period and to assess their impact on the process of economic development. The degree of originality is given by our choice to focus on the comparative analysis of two periods of time: 2000-2007, when the European Union as a whole, but especially Central and Eastern European countries as well as Mediterranean ones experienced significant improvements in labour market performances and overall competitiveness and 2008-2010, a recession period characterized by a massive loss of jobs and an equally large increase in unemployment, with anticipated consequences on economic growth. The main interest is to look for the key factors that determine the lasting performances of the leading European economies and possible solutions for ensuring the sustainable growth of the others.

Channels through which monetary policy affects aggregate demand can be divided into three groups: traditional interest rate channel, other asset price channels and credit channel composed of balance sheet channel (named also broad credit channel), only recently separated bank capital channel and bank lending channel. Banks face troubles in keeping their present or acquiring new financial sources, when central bank tightens its monetary policy. Banks characterized by differences in size, capitalization, liquidity and ownership face different levels of informational asymmetry and are therefore differently affected by changes in monetary policy. If larger, better capitalized, more liquid, state owned and/or domestically owned banks respond weaker to changes in monetary policy it is possible to argue that bank lending channel is effective. This hypothesis is tested on a panel of annual data for individual Slovenian banks in the period between 1993 and 2007 using general method of moments. Results largely confirm the existence of the bank lending channel in Slovenia.

This study is a contribution to the empirical literature on the significance of productivity shocks in explaining a high saving-investment correlation, using data from a panel of 21 OECD countries over the period 1970-2003. The study looks at the distributional properties of the productivity shocks in order to test if productivity shocks can relate saving to investment. To this end, we divide the countries into three groups with respect to the distributional characteristics of productivity shocks in each country with an application of the Fuzzy-c-means (FCM) clustering technique. The results provide some support for the productivity shock argument, indicating that the saving retention coefficients are greater for the countries subject to large productivity shocks in magnitude.

This paper analyses the crucial factors determining the foreign direct investment (FDI) going to the privatized glass sector in the Czech Republic. In our research we felt that there was a scant evidence in Central and Eastern Europe of the determinants of foreign direct investments (FDI) at the micro level and we were aware of the endogeneity issue of FDI. The aim of this paper is to fill these gaps. The choice of the glass sector allows for an analysis of a firm's micro characteristics that attract foreign direct investors in an industrial sector, while reducing the impact of macroeconomic factors in their choice. Our econometrical analysis, using original panel data from 1990 to 2006, gives strong evidence that foreign direct investors in the glass sector in the Czech Republic have chosen larger and more profitable firms that were intensively restructured and privatized at the beginning of the transition. Our results support the relevance of the endogeneity issue in the choice of foreign direct investors in transition countries.

This paper assesses whether the legal independence granted to the Central Bank of Egypt (CBE) by the latest legislation promulgated in 2005 is factual. The author followed Fry's methodology, which assumes that the level of independence of the central bank is determined by fiscal attributes. In an attempt to develop Fry's method, there was used a simple criterion to assess the central bank's independence, namely, that the central bank is actually independent if it can fulfill its money supply target without squeezing the private sector. Applying this criterion to the case of the CBE, we find that the legal independence granted to the CBE by the latest legislation is not factual.

EVA is a useful tool for assessing company performance. It combines factors, such as economy, accounting and market information in its assessment. This study employed EVA in an attempt to compare the companies' performances of GLCs (government-linked companies) and non-GLCs. Based on a 4-year pooled panel data of 37 GLCs and 208 non-GLCs, the results show that companies with government as their stakeholders tend to exhibit lower EVA scores than the companies without government stakeholders in Malaysia. Larger size companies were found to have lower EVA values. Companies which have both the characteristics - which are simultaneously large in size and government-owned, tend to be most adversely affected. Thus, any increment in the size of company for GLCs would decrease or destroy the value of the company, and to a greater degree, than companies without government holding.

Moral hazard agency problems take place when risky debt is issued. The dominant shareholders have opportunities to make decisions which effect wealth transfer. In several recent theories, debt-equity choice, which deals with agency problems assumes that financing and investment decisions are separable. These studies have been criticized due to the fact that both decisions are interdependent. The purpose of the presented paper is to test empirically the moral hazard problem of debt-equity choice in Indonesia. This study provides evidence that the level of debt is not secured by the sufficient collateral and is also not supported by growth opportunities. It seems that Indonesian companies use debt also to finance operations and not only for real investment.

Foreign direct investment (FDI) is an important phenomenon in international economic relations. Generally, FDI is studied from the point of view of capital and technology transfers to the recipient countries while respecting a basic fact that profit is the main investor's interest. In this paper in Part 2, some representative examples of typical FDI models are presented, whereas Part 3 should justify the specification of a model which is formulated and applied in Part 4. Investors can be driven by the expectation of maximum profit which would be obtained by allocating FDI according to the exchange rate volatility, i.e. after a sudden large devaluation of the host country currency large FDI inflows will follow as future appreciation is expected. Large exchange rate shocks are described with the help of skewness. Negative skewness means that the appreciations occur more often. Reasoning of the model explaining FDI by mean, standard deviation and skewness of changes of exchange rate is provided. An application to two New EU Members and two ASEAN countries is presented using panel data and seemingly unrelated regression technique.

The purpose of this study is to investigate the sustainability of current account of 22 OECD countries by employing Liu and Tanner (1996) testing procedure. The procedure used here is to examine stationarity of current account. By using ADF unit root test on single time series, it has been found that current account of most OECD countries have unit root. This outcome, however, might be due to the generally low power of this test. The aim of this paper is to reconsider this issue by exploiting the extra information provided by the combination of the time-series and cross-sectional data and the subsequent power advantages of panel data unit root tests. We apply the test advocated by Im, Pesaran and Shin (1997). According to estimation, current account deficits in OECD countries are sustainable.

This paper uses panel data from the German car industry for the estimation of parameters of a demand equation applying different statistical methodologies and paying special attention to advertising variables. Two important conclusions can be drawn. First, advertising plays an important role in this market but its effectiveness depends on its form and type of message; and second, the marketing policy of a firm has to take into account the size of its cars.

Long-term growth convergence has extensively been investigated based on economic variables. Indicators of social development and health status are generally focused on their contribution to growth or on assessing national health care systems. Yet, as a general yardstick of well-being, life expectancy should be regarded as a criterion to measure crosscountry development patterns over long periods. Following a review of two approaches to estimating convergence, hypotheses and findings of recent studies on public health and growth are examined. Reformulating the analytical framework of both strands of research, discrete choice and parametric and semi-parametric Poisson regressions are applied to a three-decade panel of 132 countries. Determinants of achievements tend to impact differently across countries, with this distinction occurring particularly between negative and positive counts. Indications of convergence are tempered by results accounting for possible non-linear relationships, which further highlight the discrepancy between country groups with average life expectancy losses and gains.

This paper works with a broad data sample of Czech voucher-privatized firms. The period of 1996 - 1999 enables to capture true post-privatization effects. It analyzes the effect of ownership structure on corporate performance and firm's characteristics. Results show that overall ownership concentration cannot be associated with improving corporate performance. Further, particular types of domestic owners do not affect firm's performance but they do affect firm's characteristics. Effect of foreign owners is limited. No clear or unambiguous effect of changes in ownership structure on corporate performance emerged.
