Does aid affect inequality?

We show that there was a negative correlation between pro-poor aid and inequality in the period before the mid-2000s. This article provides an explanation for this observed relationship. Using panel data on 34 countries for the period 1996–2014, we test the hypothesis that pro-poor aid has an inequality-reducing effect. To demonstrate that the negative correlation is not spurious, we use dynamic panel techniques with alternative specifications. We show that the share of pro-poor aid has a negative effect on inequality. In addition, we show that the interaction term between the poverty rate and the change in pro-poor aid has a significant effect. These empirical results are consistent with our theoretical predictions. The results imply that aid can reduce inequality by altering the allocation of aid, rather than by increasing the amount of aid.     

How strongly can industrial structural transformation affect GDP?

It is well known that when a country develops, its leading industry shifts from agriculture to non-agriculture. This industrial structural transformation has recently attracted considerable attention from scholars. Then, how strongly can this industrial structural transformation affect a country’s income? In this study, we shed light on this research question. More specifically, we measure magnitudes of the industrial structural transformation’s influence on GDP, by examining the following counterfactual GDP. We calculate a country’s counterfactual GDP when the country specializes in agriculture. If the counterfactual GDP is considerably small without the non-agricultural sector, this suggests that the industrial structural transformation from agriculture to non-agriculture is considerably important, in terms of GDP. We use Japan as our sample economy. Consequently, we find that the counterfactual GDP is surprisingly small, which suggests that the industrial structural transformation’s influence on GDP is surprisingly large. We also find that one of the main factors responsible for the surprisingly small counterfactual GDP is land, which has not been deeply examined.     

Does microfinance affect income inequality?

This study addresses the question whether participation of the poor in microfinance contributes to reducing a country’s level of income inequality. Using data from 70 developing countries, we show that higher levels of microfinance participation are indeed associated with a reduction of the income gap between rich and poor people. We also show, however, that the effects of microfinance on reducing income inequality are relatively small. The results of this study add to the discussion on the impact of microfinance on poverty by showing that, although access to microfinance does seem to improve the relative income position of the poor, this improvement is modest, which is probably because the use of microfinance is generally small as compared to the size of the economy of the countries in our sample. Microfinance should, therefore, not be seen as a panacea for bringing down income inequality in a significant way.     

How large are wage differentials in Austria?

The OECD has repeatedly recommended that wage bargaining in Austria be decentralised to allow wage diferentials to widen. But the status quo itself is in question. While studies of aggregate industry data indicate a high degree of wage dispersion, research based on data from household surveys seems suggest that income inequality in Austria is as small as in the Scandinavian countries. This paper seeks to reconcile these opposing views. It shows that data from the household surveys underestimate the size of inter-industry wage differentials. An analysis of the structure of contractual wage rates supports the view that wage inequality is very pronounced in Austria and that a narrowing of the wage gap would lead both to an increase in productive efficiency and an increase in income equality.     

Could immigration explain wage inequality in a skill-biased technological model?

The aim of this paper is to evaluate how immigration of high-skilled workers affects the technological-knowledge bias and, in turn, the skill premium in the host countries, in particular bearing in mind the recent experience in a number of European countries. We study a skill-biased dynamic general equilibrium R&D growth model in which the standard R&D technology is modified so wage inequality results from the direction of the technological knowledge, which in turn is induced by the price channel. By solving the transitional dynamics numerically, we show that the rise of the skill premium arises from the price-channel effect, complemented with a mechanism that reflects the impact of immigration on R&D. According to our quantitative results, our model is able to account for a significant proportion of the dynamics of the skill premium in the data for a number of European countries, thus, suggesting that differences in labour skills between immigrants and natives are, in practice, an important source of skill premium variation over time.     

Institutional quality and skilled–unskilled wage inequality

This paper establishes two-sector general equilibrium models in the presence of unproductive activities to investigate how an improvement of the institutional quality influences the skilled–unskilled wage inequality. We find that an improvement of the institutional quality will affect the interest rate, and then the interest rate combining with the capital intensity will generate an impact on the skilled–unskilled wage inequality. Specifically, both the interest rate and comparisons of the capital–labor relative distributive shares between two sectors play an important role in determining the skilled–unskilled wage gap in an economy featured with unproductive activities. The above results are robust even when we extend the basic theoretical model in several different ways.     

Male wage inequality and marital dissolution: Is there a link?

After almost a century‐long pattern of rising marital instability, divorce rates levelled off in 1980 and have been declining ever since. The timing of deceleration and decline in the rates of marital dissolution interestingly coincides with a period of substantial growth in wage inequality. This paper establishes a novel connection between the two phenomena and discusses potential explanations for the underlying link. Using female marital histories in a duration analysis framework combined with regional and temporal variation in the pattern of male wage dispersion, I show that inequality has a significant stabilizing effect on the marriage. Quantitatively, increases in male wage dispersion can roughly explain up to 30% of the fall in the mean separation probability between 1979 and 1990. Several plausible explanations are discussed: changes in spousal labour supplies, female wage inequality, income uncertainty, social capital as well as a hypothesis where inequality renders the option to divorce less attractive by making remarriage more difficult.     

How does informal employment impact income inequality?

This study investigates how informal employment impacts total income inequality in urban China. Finite mixture methodology is employed to examine the segments that exist in the informal labour market, and the Theil index (T0) is used to break down total income inequality according to different subsamples. We found that the two-segment model (upper-tier and lower-tier) best describes the structure of the informal labour market in urban China and that the upper-tier segment contributes most to the total income inequality.     

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.     

Does wealth inequality affect the transmission of monetary policy?

We provide evidence that higher wealth inequality between households is associated with stronger real effects of monetary policy. First, we use state-dependent local projections to show that the US and the UK exhibited stronger real effects of monetary policy in times of higher wealth inequality. Second, we measure wealth inequality within US states and document that economic activity responds more strongly to interest rate changes in states where wealth is distributed more unequally. Third, we show that ECB monetary policy has stronger real effects in Euro Area countries with higher wealth inequality.     

Does unconventional monetary policy affect inequality? Evidence from Japan

Inequality has been largely ignored in the literature and practice of monetary policy, but is gaining more attention recently. Here, we exclusively focus on the impact of unconventional monetary policy (UMP) on inequality. We look at how the recent UMP in Japan affected inequality, using household survey data. Our vector auto regression (VAR) results show that UMP widened income inequality after 2008Q3 as the Bank of Japan (BoJ) resumed its zero-interest rate policy and reinstated UMP. This is largely due to the portfolio channel. To the best of our knowledge, this is the first study to empirically analyse the distributional impact of UMP. Japan’s extensive experience with UMP may hold important policy implications for other countries.     

How international financial flows affect stock markets?

Relying on the IMF Coordinated Portfolio Investment Survey, which reports countries’ bilateral investments in financial assets at end-2001 to end-2015, this article shows that a country’s stock market growth is not only spatially correlated with those of nearby countries, but also positively associated with the magnitude of connectedness of the country’s international investments in debt within a dynamic financial investment flow network. The positive relation arises because debts have become an increasingly important source of capital for developing countries.     

How does organizational structure affect executive compensation?

Does the rise of the CFO as the second-ranked executive increase the status of the CEO? We find that, as a CFO becomes #2, a CEO receives higher pay in relative terms compared with other top executives. This result corresponds to the literature on span-of-control of executives in top management team.     

How does the internet affect migration decisions?

This article provides new evidence on the impact of the internet on migration decisions. I find that an increase in internet adoption among migrant-sending countries reduces the stock of migrants from these locations. The results are robust to a number of specifications, including an instrumental variable approach that addresses the endogeneity of internet adoption. The findings suggest that the internet may weaken the importance of push factors in the decision to migrate, and that these effects outweigh declines in mobility costs.     

Does downward nominal wage rigidity dampen wage increases?

Focusing on the compression of wage cuts, many empirical studies find a high degree of downward nominal wage rigidity (DNWR). However, the resulting macroeconomic effects seem to be surprisingly weak. This contradiction can be explained within an intertemporal framework in which DNWR not only prevents nominal wage cuts but also induces firms to compress wage increases. We analyze whether a compression of wage increases occurs when DNWR is binding by applying Unconditional Quantile Regression and Seemingly Unrelated Regression to a dataset comprising more than 169 million wage changes. We find evidence of a compression of wage increases and only very small effects of DNWR on average real wage growth. The results indicate that DNWR does not provide a strong argument against low inflation targets.     

How do business startup modes affect economic growth?

This paper examines researchers’ choices between either collaborating with venture capitalists or going independent when investing in research (e.g., labs, scientists, equipment, perishable materials, etc.) and how their interaction affects long‐run growth in an economy characterized by incomplete contracts and financial market imperfections. We find that venture capital is more likely to be selected by entrepreneurs when startup risks are median to high. A ranking of the welfares associated with each startup mode under different legal and financial environments shows that economic policy and research incentives may not always align as entrepreneurs may not select the mode that provides the highest welfare level.     

How do financial cycles affect public debt cycles?

We employ the duration framework to study determinants of public debt cycles in 57 advanced and emerging economies over the 1960–2014 period, with a particular focus on the impact of financial cycles. The results suggest that the association between financial and debt cycles is asymmetric. Debt expansions preceded by overheating in credit and financial markets tend to last longer than other expansions, but there is no significant association between financial cycles and debt contractions. There is strong evidence of duration dependence in both phases of the cycle, with the likelihood of expansions and contractions to end increasing with the length of their respective spells. Higher initial level of debt increases the spell of contractions (persistence of adjustment effort hypothesis) and reduces the spell of expansions (debt sustainability hypothesis). The results are robust to the inclusion of global factors, openness, political stability, and debt crisis indicators as additional controls.
