Re-examining the relationship between domestic investment and foreign aid: does political stability matter?

While past studies had conflicting conclusions regarding the impact of foreign aid on growth and development of a nation, recent studies have tried to delve deeper into the question, ‘what makes aid work?’ (see, Dutta, Leeson, and Williamson, 2013; Burnside and Dollar, 2000, 2004; Svensson, 1999). This paper tests how political stability (vis-à-vis political instability) affects the relationship between domestic investment and foreign aid. Applying dynamic panel estimators, our results show that political stability affects aid’s effectiveness on domestic capital formation. The paper considers alternative measures of political stability (vis-à-vis instability), focusing on the political characteristics of a system that have the potential to make a nation stable. Political stability affects policy selection by the government positively and, thus, public resources such as foreign aid are put to the desired use. The estimated marginal impacts show that foreign aid enhances domestic investment in the presence of a stable political climate, but there is a diminishing return to aid.     

Does the version of the Penn World Tables matter? An analysis of the relationship between growth and volatility

Abstract .  The Penn World Tables (PWT) are an important data source for cross-country comparisons in economics. The PWT have undergone several revisions over time. This paper documents how countries' output growth rates change across four publicly available versions of the PWT. We show that for some countries the magnitude of the differences is significant and/or the sign of the growth rates changes across versions. Using as an example Ramey and Ramey (1995) , who found growth volatility has a significant negative effect on growth, we demonstrate that conclusions based on one version of the PWT may not hold under another version.     

On the relationship among efficiency,capitalization and risk: does management matter in local banking market?

By employing a Granger causality methodology in a panel data framework, this article explores the relationship among efficiency, capitalization and credit risk within the local Italian banking system. Focusing the attention on cooperative banks, we specifically test whether managers take more risks in highly concentrated markets (i.e. monopoly) than in partially competitive markets (i.e. duopoly). The evidence shows that in more concentrated markets, management efficiency generates a decrease in risk-taking (rejecting the bad management hypothesis) with respect to the partially competitive markets. Results are consistent with the idea that banks with less local competition are able to increase their profits by indulging more freely in rent-seeking behaviour, minimizing their risk-taking and, consequently, improving the quality of their assets through additional screening processes. The financial crisis does not seem to affect the conduct of management in terms of bank investment decisions and risk-taking. A series of robustness tests generally confirms our findings.     

How important are minimum wage increases in increasing the wages of minimum wage workers?

Popular discussion presumes minimum wage increases primarily drive wage gains for minimum wage workers. We investigate this presumption using the Current Population Survey to assess the fraction of minimum wage workers receiving raises after 12 months. This fraction is moderately higher following state minimum wage increases, and positively correlated with several measures of labor market tightness. Finally, wage gains frequently follow industry and/or occupation switches, highlighting the importance of career progression for earnings growth among entry-level workers. Career progression and increases in labor demand rather than minimum wage increases appear to drive most wage gains for minimum wage workers.     

Higher education enrolment in Bangladesh: does the wage premium matter?

This paper empirically examines the decisions of individuals to enrol in a course of tertiary education in Bangladesh, focussing on the period 1999 to 2009. Of particular interest is whether the wage premium―the gap in wage earnings between tertiary and secondary school graduates―is associated with decisions to enrol in tertiary education. The analytical framework used here is the human capital theory, which is tested through a discrete choice model. Using data from Bangladesh Labour Force Surveys, empirical results suggest that the wage premium is positively associated with decisions of males to enrol in tertiary education, while for females there appears to be no such association. A battery of robustness tests supports our results.     

Does the minimum wage help the poor?

Conventional economics frequently employs abstract analysis, including questionable assumptions regarding human behavior, together with highly quantitative methodology. While these techniques do not provide a full picture of economic life, conventional economic analysis has provided important insights and predictive power, at least during certain historical periods. The effects of minimum wage laws have been analyzed extensively by conventional economists over the past quarter century. That analysis, much of it empirical, has produced important insights into the effects of the minimum wage on the poor. In this article, I survey that vast body of research and address whether the poor are better off due to the minimum wage. I conclude the minimum wage does not unambiguously help the poor, and may do more harm than good to this segment of the nation's population.     

Building the minimum wage: the distributional impact of Germany’s first sectoral minimum wage on wages and hours across different wage bargaining regimes

The first minimum wage in Germany was introduced in 1997 for blue-collar workers in sub-sectors of the construction industry. In the setting of a natural experiment, blue-collar workers in neighboring 4-digit industries and white-collar workers are used as control groups for differences-in-differences-in-differences estimation based on linked employer–employee data. Estimation results reveal a sizable positive impact on mean wages in East Germany, but no significant effect in West Germany. Size and significance of effects are neither homogeneous across wage regimes (individual vs. collective contracts) nor across the distribution. The patterns suggest a compression in the lower part of the wage distribution and spillover effects to wages where the minimum is not binding, even in West Germany, where the bite of the MW was low. No effects on hours of work or substitution between workers of different qualification levels are found.     

Reexamining the relationship between inflation and growth: Do institutions matter in developing countries?

Using a large panel of countries during the period 1950–2009, we estimate the inflation thresholds above which its association with economic growth is expected to be negative, taking into account differences in institutions across countries. First, in line with previous literature, we find that the estimated threshold is substantially higher for developing countries compared to that of developed countries. However, we further show that the inflation threshold in developing economies falls when we consider reduced groups that exceed certain levels of institutional quality. We also find that the cost of inflation increases with the quality of institutions.     

Exploring the nexus between financial openness and informational efficiency – does the quality of institution matter?

This article examines the empirical link between financial openness and informational efficiency of stock markets in 27 emerging markets. Improving on earlier papers, this study has used World Bank’s Worldwide Governance Indicators (WGI) as the proxy of institutional development in dynamic panel data models estimated by generalized method of moments (GMM). Our results show, first, financial liberalization by itself has no impact on enhancing efficiency of stock market. Second, for countries with high level of institutional development, the interaction of trade openness and financial openness become significant. Third, for the same group of countries, interaction effect of financial liberalization and institutional development leads to more efficiency in stock market. Hence, our finding demonstrates the utmost importance of institutional development and its role on liberalization. Our results conclude that institutional development and trade openness are pre-requisites for a country to benefit from financial openness. Our study further provides empirical evidence to theoretical model proposed by Basu and Morey (2005) that governance is the missing link between stock market efficiency and financial liberalization. Our findings suggest that policy makers in developing economies should enhance the quality of their institution in order to optimize the benefits of financial liberalization.     

The relationship between trading activity and stock market volatility: Does the volume threshold matter?

This paper examines whether trading activity conveys valuable information about changes in market volatility dynamics. We use a modelling framework, in which the market smoothly switches from one state to another, according to the volume level. Results show that large volume drives the high volatility regime for most of the markets, quite consistently with the disagreement-in-beliefs hypothesis. The volume decomposition into normal trading activity and surprising information arrival reveals a reverse threshold linkage for emerging markets. Results support the sequential information arrival hypothesis and highlight the key role of asymmetric information and thin trading in modelling the volume-volatility relationship. The proposed volume-based models provide significant forecast improvements over competing models and offer scope for investors to earn substantial profits.     

An international comparison of hospital efficiency: does institutional environment matter?

The consensus among many health economists is that no meaningful performance differences exist among for-profit and non-profit hospitals in the US, but this topic has continued to be a matter of academic, judicial, and public policy interest. A similar debate has ensued internationally, regarding the potential efficiency gains from privatization of public enterprises. In this paper, we examine empirical evidence from the public, highly regulated Norwegian hospital sector and the private, highly competitive and unregulated California hospital sector to ascertain whether institutional environment and level of market competition significantly affect the degree of productive efficiency in hospitals. We compare and discuss the productive efficiency of four similar sets of hospitals operating in different institutional and competitive environments. The four samples are carefully matched in the dimensions of sample size, hospital size, and average lengths of stay. Heterogeneity in output definition is used to control for other dimensions (casemix, age distribution of patients). We use Data Envelopment Analysis (DEA) to estimate and compare average long-run as well as short-run efficiency measures across groups. We find that scale and scope regulation of Norwegian hospitals improves long-run efficiency, primarily due to better utilization of capital.     

Has the EMU reduced wage growth and unemployment? Testing a model of trade union behavior

Grüner (2010) argues that the introduction of the European Monetary Union (EMU) led to lower wage growth and lower unemployment in participating countries. According to Grüner, monetary centralization increases the amplitude of national business cycles, which leads to higher unemployment risk. In order to counter-balance this effect, trade unions lower their claims for wage mark-ups, resulting in lower wage growth and lower unemployment. This paper uses macroeconomic data on OECD countries and a difference-in-differences approach to empirically test the implications of this model. Although we come up with some weak evidence for increased business cycle amplitudes within the EMU, we neither find a significant general effect of the EMU on wage growth nor on unemployment.     

Acquirer's return and the choice of acquisition targets: does acquisition experience matter?

We study a sample of 6503 UK acquisitions completed between 1985 and 2004 and control for previous deals similarities. Returns for frequent acquirers decrease constantly but they remain positive through high-order deals. We do not detect an improving pattern of returns but, at best, a stable one when the deal is settled for cash. Using ‘characteristics-based’ experience variables, our multivariate analysis shows that the acquirers’ returns are unaffected by prior acquisition experience. However, we find solid evidence for acquirers drawing inferences from prior experience in designing the method of payment, selecting the organizational form of the target firm and engaging in focused acquisitions, which is consistent with learning through acquisitions. The results are robust to various consistency checks.     

Loss of control: legislature changes and the state–local relationship

There are a variety of methods that state legislatures can use to pass legislation which relates to municipalities. This paper explores why, how and when states changed their constitutions from allowing special legislation for municipalities to requiring general laws which would apply to all municipalities. Historians have put forward several explanations for why special legislation was harder to maintain as the nineteenth century progressed. A new way of framing the story is presented here by considering how the passage of special legislation was maintained through a logroll; legislators formed a coalition to vote on each other’s local legislation. As the size of the legislature expanded and the composition of the legislature changed, it may have been harder for legislators to maintain a coalition in order to logroll each other’s proposed local legislation. The previous theories along with the new one presented here are empirically tested. Evidence suggests a link between the size of the state legislature and the probability of instituting general legislation for municipalities, indicating that one motivation for adopting general laws was the dissolution of a stable logroll.     

Employment and the risk of domestic violence: does the breadwinner’s gender matter?

This article studies the effect on the risk of female victimization of the employment status of the woman and her partner. We use individual-level data from the violence against women surveys for Spain, which also provide information on income and a rich set of sociodemographic characteristics. To address the potential endogeneity of the binary employment indicators, we exploit exogenous geographical information on the employment and unemployment rates by gender and age, within a multivariate probit framework. Our estimation results show that male partner employment plays a major role in the risk of physical violence, while female employment only lowers it when her partner is employed too. The lowest risk appears for more egalitarian couples in which both partners are employed.     

An empirical analysis of disinvestment policy in India: does ideology matter?

Using panel data estimation for limited dependent variables and sample selection models, we identify political, industry specific, firm specific and macroeconomic variables which influenced the decision to divest central public enterprises in India between 1991–2010. We find that higher partial privatization is driven by a more right-winged coalition, lower ideological spread in the coalition and lower ideological difference between the center and the state in which the public enterprise is located. We also find that after the government selects larger, more experienced and more profitable firms, it divests the relatively less experienced and less profitable firms to a larger extent.     

Shadow economy and unemployment rate in USA: is there a structural relationship? An empirical analysis

This article aims to estimate the size of the US shadow economy (SE) using a structural equation approach and to evaluate if a structural relationship exists between the SE and the unemployment rate (UR) in the United States. The size of the SE is estimated to be decreasing over the last two decades. We corroborate the existence of a structural relationship between the SE and the UR by using a simple theoretical model. Furthermore, we extend the Okun's law to estimate the structural relationship between growth rate of official GDP, SE and UR. Our results indicate a significant positive relationship between the SE and the UR.     

Growth in Africa: does the source of investment financing matter?

This paper examines empirical evidence for 11 sub-Saharan African countries on the relationship between economic growth and three principal sources of investment funds: foreign aid, foreign direct investment, and domestic saving. In light of the shortcomings of traditional cross-section analyses, the time series approach is used instead. Modern time series methods are rigorously applied, beginning with unit root tests and followed by model specifications that reflect the revealed temporal behaviours of the variables in each of the 11 countries. Domestic saving seems to play a somewhat more important role in generating economic growth than foreign direct investment or foreign aid. However, the mixture of results across the 11 countries implies that, in general, it is not possible to rank one source of investment financing ahead of any other.     

The effect of immigration on unemployment in Europe: Does the core-periphery dualism matter?

The migrant crisis is one of the most challenging tasks the EU has ever faced. This paper uses a Panel Error Correction Model to assess the direction of the impact of immigration on domestic unemployment, in the short and in the long run, for a sample of 15 EU countries between 1997 and 2016. We test for different effects in core and periphery countries based on differences in macroeconomic fundamentals and labor market characteristics. In the long run, immigration is found to reduce unemployment in peripheral countries only, whereas in the short run, we find that immigration reduces unemployment for the whole sample. However, country-specific coefficients based on interactions with labour market characteristics indicate that short-run impacts are larger in Scandinavian and Anglo-Saxon countries. Conversely, Italy, Greece and Portugal show the smallest impacts. Our results suggest that negative sentiments toward immigration due to labour market competition are mostly unjustified.
