Are government wages interlinked with private sector wages?

The ongoing fiscal and financial crisis with significant macroeconomic imbalances in the euro area raises the question in how far public–private wage interaction and even wage spirals contribute to fiscal and competitiveness problems. In this vain we analyse empirically whether the evolution of public sector wages is decoupled from that of the private sector. Using data for number of OECD countries, we find: (i) a strong and extremely robust positive annual contemporaneous correlation of public and private sector wages over the business cycle; (ii) evidence of co-movement of these variables over the medium and long run. From a policy perspective, the findings of this study suggest public wage restraint and private wage flexibility coupled—where needed—with institutional reform to prevent or break public–private wage spirals.     

Real and financial shocks,exchange rate regimes and the probability of a currency crisis

We analyze the relationships among shocks, exchange rate regimes, and capital controls in relation to the probability of a currency crisis. Based on the theoretical model by Nakatani (2016, 2017a), we use panel data on 34 developing countries and apply a probit estimation. We find that both productivity shocks and risk premium shocks trigger currency crises, whereas productivity shocks are important for severe currency crises. We also find that the effects of these shocks on the probability of a crisis are larger for floating exchange rate regimes and that capital controls mitigate the effects of productivity shocks in pegged regimes.     

Remittances,growth and poverty: New evidence from Asian countries

The present study re-examines the effects of remittances on growth of GDP per capita using annual panel data for 24 Asia and Pacific countries. The results generally confirm that remittance flows have been beneficial to economic growth. However, our analysis also shows that the volatility of capital inflows such as remittances and FDI is harmful to economic growth. This means that, while remittances contribute to better economic performance, they are also a source of output shocks. Finally, remittances contribute to poverty reduction – especially through their direct effects. Migration and remittances are thus potentially a valuable complement to broad-based development efforts.     

Public expenditures on education, human capital and growth in Canada: An OLG model analysis

Much of the current debate in ageing countries focuses on whether governments should increase investments in human capital. We address this issue by simulating the effects of additional education spending using an overlapping-generations model applied to Canada. In the context of population ageing, the results indicate that how the policy is funded has powerful impacts on the targeted outcomes. Higher education incentives may increase the rate of human capital accumulation and mitigate the negative effects of slowing labour force growth. However, the impact depends on the distortions implied by alternative tax instruments and the efficiency of public expenditures on education.     

The IPO phenomenon in the 1990s

Initial Public Offerings (IPOs) were the most prevalent form of securities issued to raise capital by firms wanting to go public during the last decade (1990–2000) in the United States. The IPO phenomenon got a tremendous boost during the late 1990s by the popularity of the Internet stocks. In the so-called ‘bubble period’ of 1998–1999, hardly a week went by when one or two IPOs, particularly of the Internet variety, did not appear in the capital market. In this paper we have analyzed the IPO phenomenon during 1990–1995 and during 1996–1999. We have also focused on Internet bubble during 1998–1999, and the IPO meltdown after March 2002. We have found that not all IPOs performed well in 1999, the majority of the 25 IPOs that had the highest first-day gains over 200% in 1999 had also a poor performance record during 2001–2002. As the IPOs issued now are few in number, we may not see the kind of ‘irrational exuberance’ as we witnessed in the late 1990s, for the foreseeable future in the United States.     

Global imbalances and household savings: The role of wealth

Many claim that fluctuations in U.S. private savings help to create and to sustain global imbalances because of their influence on the current account deficit. To test this claim, this paper investigates the determinants of aggregate household savings using a panel of 18 developed countries for the period 1980–2005. We weave two strands of literature: the first strand from consumer theory, considering specifically the ‘wealth effect’, the second strand from aggregate private savings theory. The original contribution of this paper derives from the main explanatory variables of the household savings function: two measures of household wealth, the first a financial variable and the second a variable for tangible/housing stock. The salience of these variables has not been tested before. The model is then enriched with variables taken from the private savings literature. To find the best technique to estimate the long run savings function, unit root and cointegration tests are carried out, from which evidence of a cointegrating relationship is found. The group means FMOLS is used to estimate the model. The empirical evidence suggests effects consistent with theory: an increase in wealth negatively affects household savings. Furthermore, when important explanatory variables, such as government savings and population dependency ratios, are included in the model, tangible wealth becomes the only kind of wealth to (weakly and negatively) influence household savings in developed countries. In the U.S. however, wealth does not seem to affect household savings negatively, it seems instead that government savings and population changes better explain the decline of savings during the past two decades. This finding provides additional evidence on the issue of global imbalances, and suggests that the recent booms of the stock and the real estate markets should not be blamed for the decline in U.S. household and private savings.     

R&D in a post centrally-planned economy: The macroeconomic effects in Poland

Half a century of centrally planned policy in the Central and Eastern European countries resulted in outdated technologies, inefficient allocation of resources and low productivity. Following the end of communism there was a fifteen year process of transition which ended in 2004 with eight post-communist countries joining the European Union (EU) of which Poland was the largest. As part of the EU these countries now face the challenge of the common EU strategy Europe 2020, which has set the target of achieving R&D expenditure to GDP ratio (called the R&D intensity) of 3% by 2020 for the Union as a whole in an effort to increase the competitiveness of the region. Poland, like the other post-communist countries, faces a lower target of R&D intensity, set at 1.7%. Nevertheless, the challenge is immense, since the country is still at only half that level and has little experience in developing policies to help achieve it. In this paper we tested two possible policy options to achieve the target: (1) to increase government expenditures on R&D and; (2) to provide tax relief on R&D to businesses. The method applied to assess the options is a recursive dynamic computable general equilibrium (CGE) model for Poland with an explicit link between productivity and R&D stock. The results show that achieving the R&D intensity target via the use of tax relief is 2.5 times more costly to the government budget, but it has a greater impact on the economy in terms of a higher GDP growth. Tax relief proved efficient in the short run while in the long run the government expenditure policy provides better value for money.     

China–Africa financial markets linkages: Volatility and interdependence

The China–Africa relationship has blossomed in recent years and the scale and scope of Chinese engagement and investment in the latter have expanded enormously in the last decade. The purpose of this paper is to analyse the dynamic linkages and volatility transmission mechanisms between Chinese and African stock markets in recent years while highlighting the relative importance of Chinese capital flows and investments. We utilise dynamic forecasting models including Bayesian VAR and BEKK GARCH to estimate both price and volatility behaviours of Chinese and 15 selected African stock markets. Our empirical results indicate strong evidence of spillover effects in terms of both price movement and volatility behaviour, implying that Chinese and African stock markets are showing signs of integration. For price movement, bidirectional feedback relationships between Chinese and most of the African stock markets are observed, suggesting that both Chinese and African stock markets could influence each other. China has been building a strong African partnership and, therefore, increasing its trade and investment influences in the region. Examining volatility transmissions, at least one spillover effect (shock and/or volatility) from China to most of the African stock markets is reported. This suggests that the Chinese stock market now plays an influential role across African stock markets given that it has major investments in 46 out of 54 countries. Our findings show important portfolio management implications as a surge in Chinese investments provide new portfolio diversification opportunities for international investors. Policy-wise, we believe further market-oriented reforms and carefully designed and long-term development policies are required to boost capacity for development and achieve sustainable trade and growth.     

Macroeconomic and financing determinants of out of pocket payments in health care: Evidence from selected OECD countries

In this paper, we examine the impact of macroeconomic, as well public and private health insurance financing (PHI) factors on out of pocket (OOP) healthcare expenditures, by using fixed/random effects and dynamic panel data methodology to a dataset of 26 EU and OECD countries for a period lasting from 1995 to 2013. The existing empirical literature has focused on testing the hypothesis that several macroeconomic and health financing determinants have an effect on OOP healthcare expenditures. Nevertheless, the related articles have not well tested the hypothesis concerning the potential impact of PHI financing on OOP spending. We find that public and PHI financing have a significant countervailing effect on OOP spending. Moreover, we show that unemployment rate has a significant positive impact on OOP expenditures. Sensitivity tests with variation of specifications and samples show that our findings are robust. We argue that policy-makers should give serious consideration to PHI institution; our results indicate that there is an inverse effect on OOP spending. We suggest that our examined countries have to provide financial risk protection to their citizens against OOP payments, rather than only attending health budgetary retrenchments in order to adjust public finances.     

The efficiency of government spending on health: Evidence from Europe and Central Asia

This paper uses data envelopment analysis (DEA) to evaluate health expenditures to demonstrate how productivity has changed over time for 46 selected countries in Europe and Central Asia. Our results show that countries could have increased output by 1.2% given the existing level of inputs. The patterns of efficiency change for the observed countries are further analyzed using the Malmquist productivity index (MPI). Decreased productivity growth is related to technical change. Finally, we regress efficiency scores on a set of environmental variables using a Tobit model. The positive influence of hospital beds and primary schooling on efficiency scores demonstrates that countries with better medical environments and a greater number of educational years may enjoy increased efficiency. In addition, there exists a regional effect between Europe and Central Asia.     

Fiscal stringency and fiscal sustainability: Panel evidence from the American state and local governments

Most state (and local) governments in the U.S. operate under formal fiscal rules which limit their ability to run budget deficits and resort to debt financing. A priori, one would expect to find evidence in favor of an intertemporally balanced budget, or fiscal sustainability, for these states, especially those characterized by a relatively high degree of fiscal stringency. We test this hypothesis for a panel of 47 state–local government units (1961–2006) using four budget balance definitions and several subsamples defined based on regional classifications, or presence of certain balanced budget requirements (BBRs). Our results, obtained from panel estimation techniques that allow for general forms of serial and cross-sectional dependence, suggest that a sufficient condition for “strong” sustainability is consistently satisfied for the full sample and all subsamples in relation to balances that include special funds and/or federal grants. However, we find evidence consistent with the “weak” version of sustainability for the full sample and some regional subsamples (particularly Far West dominated by California) in at least one of the two balances that exclude these items. Finally, the BBRs seem to matter only in relation to the sustainability of the more narrowly defined balances. We discuss the implications of these findings for the role of fiscal rules and federal grant policies.     

Does the Internet increase labor productivity? Evidence from a cross-country dynamic panel

The Internet has various economic functions and is a fundamental part of most economic activities and transactions. In this paper we apply a Dynamic Panel Data approach to study the impact of the Internet on labor productivity using data from 108 countries for the period 1995–2010. The results of the study show that the Internet has positive and statistically significant effects on labor productivity. Assuming other factors stay constant, increasing the number of Internet users by one percent increases GDP per employed person by $8.16–14.6. Educational expenditures as a percentage of GNI, per capita health expenditures, trade and gross capital formation as a percentage of GDP also have positive and statistically significant effects on labor productivity.     

A Romerian contribution to the empirics of economic growth

Mankiw, Romer, and Weil (1992) made the Solovian set up widely used to test the determinants of economic growth and the speed of convergence. In accordance with the nature of the Solow framework, almost all empirical growth studies considered technological progress constant and identical across countries and over time, and hence underemphasized its role. In this study, in order to overcome this weakness, we propose that the Mankiw, Romer, and Weil (1992) set-up should be replaced by the Solovianized Romer (1990) framework, thus allowing the role of technology to be considered in the empirical analysis. In particular, within this framework, the growth rate of technology varies across economies and over time. We estimate the convergence equation derived from Solovianized Romer model for 31 OECD countries for the period 1980–2008 by applying the system GMM approach. The empirical findings of the model support the conditional convergence hypothesis, but reveal a lower convergence rate than that predicted by the existing literature. As a policy implication, we argue that, investment in R&D and human capital are important determinants of convergence, and in cases where economies are unable to allocate sufficient resources to R&D, policy makers should ease the diffusion of technology (e.g., via FDI or trade) in order to retain a high convergence rate.     

Decentralization and growth: Do informal institutions and rule of law matter?

We develop a model of the interactions among decentralization, informal institutions and the rule of law. The model sheds light on the ambiguous empirical results reported in the literature regarding the growth effects of the policy of devolving fiscal responsibility to local governments. We find that the distribution of civicness within a country determines the magnitude of the effects of decentralization on its regional convergence, as well as whether decentralization fosters or dampens the country’s national growth. We perform a series of simulated “reforms” using Monte Carlo methods parameterized using OECD countries data set. We then test our findings using a panel data set of 23 OECD countries covering the period 1975–2010. We find that the short and the long run growth effect of decentralization policy depends on the size of the policy reform and can range from extremely negative to positive depending on the rule of law, the level of social capital and its regional dispersion, in line with the model predictions.     

A model of the inflationary process in six major O.E.C.D. economies: Empirical results and policy implications

In contrast to most recent empirical work on inflation which has concentrated on the size and stability of coefficients in the wage equation, this paper provides a reexamination of the price equation. Evidence is presented on the structural determinants of inflation in six large industrial nations. It is demonstrated that price equations which include capital costs and excess demand among the regressors perform exceedingly well according to the usual statistical criteria. The results of this study indicate that the inflationary process possesses a high degree of uniformity among the larger industrial countries. This pertains not only with respect to the specific independent variables in price equations, but also with respect to the high degree of uniformity of the estimated coefficients. Additionally, the findings indicate that lower productivity growth and higher capital costs have contributed significantly to the inflationary process since 1974. Furthermore, since higher capital costs are one consequence of tighter monetary policies, the adoption of such policies in response to the two oil price shocks of the 1970s may have offset their intended deflationary effects on prices through the linkage of wage costs and aggregate demand.     

Effect of financial development on economic growth in sub-Saharan Africa

This paper examines the overall economic growth effect when the growth in finance and real sector is disproportionate relying on panel data for 29 sub-Saharan African countries over the period 1980–2014. Results from the system generalized methods of moments (GMM) reveal that, while financial development supports economic growth, the extent to which finance helps growth depends crucially on the simultaneous growth of real and financial sectors. The elasticity of growth to changes in either size of the real or financial sector is higher under balanced sectoral growth. We also show that rapid and unbridled credit growth comes at a huge cost to economic growth with consequences stemming from financing of risky and unsustainable investments coupled with superfluous consumption fueling inflation. However, the pass-through excess finance–economic growth effect via the investment channel is stronger.     

Financial efficiency and accounting quality: The impact of institutional micro-factors on FDI

In this paper, we explore whether factors such as financial markets and accounting qualities contribute to foreign direct investment (FDI). We use a unique data source: the survey data from World Economic Forum, to measure the efficiency of the financial markets and the quality of accounting standards. With this unique data, we demonstrate that financial markets and accounting quality are important factors of FDI inflow into a country. In particular, FDI is positively correlated with the strength of financial audits and reporting standards and venture capital availability for all countries. We also show that accounting quality measures are more important for developing and emerging countries than for developed countries. On the other hand, financial market measures, especially the access to venture capital, have a bigger impact in attracting FDI flow into developed countries. These results support the hypothesis that local financial markets and accounting quality affect FDI. The results have strong policy implications for governmental regulatory agencies.     

Spillover effects of taxes on government debt: a spatial panel approach

It is claimed that tax policy is neither time- nor space-independent due to cross-border tax base mobility, which induces spillovers. Specifically, fiscal shocks in one country are supposed to have an impact on fiscal policies in other countries. Different types of taxes influence economies differently. This paper addresses the question of their impact on government debt. Within a framework of spatial econometric modeling, we evaluate the impact of capital, labor and consumption taxes on public debt in 34 European countries in 2002–2011, and find strong spatial spillovers. We show that a consumption tax and, to a lesser degree, a capital tax significantly affect the sovereign debt, and that the global relations play a leading role (i.e. dominate the local ones) in shaping fiscal policy.     

Macroeconomic effects of public investment in South-East Europe

This paper provides the first cross-country study of the macroeconomic effects of public investment in South-East Europe. For these countries, we construct a unique dataset of exogenous changes in public investment and use them with Jordá (2005) local projections method to estimate their dynamic effects on the main macroeconomic aggregates, the unemployment rate and debt-to-GDP ratio. Our results show significant multiplicative effects of public investment on GDP, delivered primarily through crowding in of private investment. Our analysis confirms that public investment can be seen as a catalyst of positive spillover effects to other sectors of the economy and thus contribute to productivity growth.     

Social capital and health at the country level

This study examines the relationship between social capital and health. We use various estimation methods such as pooled OLS, a split-sample approach, a quadratic regression, and fixed effects model to investigate country-level unbalanced panel data of 194 countries for the time period 1990–2015. The results support the negative effect of bonding social capital and the positive effect of bridging social capital on health. The effects are more pronounced in low income countries. The first contribution of the paper is to better explain the mixed results of previous studies by focusing on the distinction between the two types of social capital. The second contribution of the paper is to address endogeneity and nonlinearity problems and to capture dynamic change by using various econometric methods. The findings imply that the socio-economic effects of social capital are different depending on the type of social capital.
