Corruption, economic growth, and income inequality in Africa

This paper uses panel data from African countries and a dynamic panel estimator to investigate the effects of corruption on economic growth and income distribution. I find that corruption decreases economic growth directly and indirectly through decreased investment in physical capital. A unit increase in corruption reduces the growth rates of GDP and per capita income by between 0.75 and 0.9 percentage points and between 0.39 and 0.41 percentage points per year respectively. The results also indicate that increased corruption is positively correlated with income inequality. The combined effects of decreased income growth and increased inequality suggests that corruption hurts the poor more than the rich in African countries.

Corruption, Growth, and Income Distribution: Are there Regional Differences?

This paper uses panel data from 61 countries at different stages of economic development over a 20-year period to investigate regional differences in the effect of corruption on economic growth and income distribution. Using two measures of corruption, we find that there are statistically significant regional differences in the growth and distributional impacts of corruption. The largest growth impact of corruption is found in African countries while OECD and Asian countries have the lowest growth impact. On the other hand, the largest distributional impact of corruption in found in Latin America. A 10% decrease in corruption increases the growth rate of income by about 1.7% in OECD and Asian countries, 2.6% in Latin American countries, and by 2.8% in African countries. A one standard deviation decrease in corruption decreases the gini coefficient of income distribution (0–1 scale) by 0.05 points, 0.14 points, 0.25 points, and 0.33 points in OECD, Asian, African, and Latin American countries, respectively. The results are robust to various specifications, measurement of corruption, measures of investment, as well as the conditioning variables. The results have interesting policy implications for economic growth, especially in low income countries with high rates of corruption.     

Internet usage and the shadow economy: Evidence from panel data

The enormous spread of the internet in the last 20 years has been having various economic consequences. In this paper I ask whether the spread of the internet aided or abetted the shadow economy. To this end, using a panel data of 152 countries over 9 years from 1999 to 2007, I examine the empirical relationship between the degree of internet usage and the size of the shadow economy. Panel and cross-section estimation results indicate that the association between internet usage and shadow economy size strongly interacts with GDP per-capita. I also suggest and then empirically test an economic mechanism to account for this observation.     

Institutional quality and environmental pollution: MENA countries versus the rest of the world

Using data for over 100 nations over the years 2004–2007, this study examines the effect, of institutional quality on environmental pollution, focusing primarily on influences of corruption, and the shadow economy, and paying special attention to MENA countries. Controlling for a, number of factors, results show that both more corrupt nations and nations with large shadow sectors have qualitatively and quantitatively similar effects in yielding fewer (recorded) emissions; however, MENA nations have higher pollution rates. Policy implications are noted.     

Corruption: Theory and evidence from the Russian Federation

In this paper, we provide theory and evidence on the problem of corruption in the Russian Federation. Our theoretical model indicates that in the presence of official corruption, the numbers of tax inspection (collection) employees could be inversely related to per capita tax collection. Our empirical analysis supports our theoretical model, shedding light on one of the most intractable problems in the Russian Federation.     

On the suitability of income inequality measures for regional analysis: Some evidence from simulation analysis and bootstrapping tests

The paper looks at the sensitivity of commonly used income inequality measures to changes in the ranking, size and number of regions into which a country is divided. During the analysis, several test distributions of populations and incomes are compared with a ‘reference’ distribution, characterized by an even distribution of population across regional subdivisions. Random permutation tests are also run to determine whether inequality measures commonly used in regional analysis produce meaningful estimates when applied to regions of different population size. The results show that only the population weighted coefficient of variation (Williamson’s index) and population-weighted Gini coefficient may be considered sufficiently reliable inequality measures, when applied to countries with a small number of regions and with varying population sizes.     

Earthquake risk and housing prices in Japan: Evidence before and after massive earthquakes

The hedonic pricing approach is used to examine whether homeowners and/or renters alter their subjective assessments of earthquake risks after massive earthquakes. Using nation-wide household panel data coupled with earthquake hazard information and records of observed earthquakes, we find that there are some modifications of individuals' assessments of earthquake risk in both cases. We have carefully taken into consideration the bias stemming from the use of objective risk variables as a proxy for individual risk assessments. Our results suggest that the price discount from locating within a quake-prone area is significantly larger soon after earthquake events than beforehand. We argue that the most likely interpretation for this result is that households tend to underestimate earthquake risk if there has not been a recent occurrence.     

产权性质、高管薪酬与高管腐败——来自中国上市公司的经验证据

文章以2007-2012年A股上市公司作为研究样本,根据腐败行为发现的可能性将上市公司高管腐败分为显性腐败和隐性腐败。实证研究发现:(1)对于显性腐败,高管高薪可以起到抑制腐败的作用,但是由于国有企业天生与政府存在亲属关系,这种抑制作用要弱于非国有企业;(2)对于隐性腐败,高薪并不能起到抑制腐败的功效,并且高管薪酬与隐性腐败存在正相关关系,支持了管理层权力理论。相对于国有企业,非国有企业高管薪酬与隐性腐败的正相关关系更为显著。     

Demand for labour inputs and adjustment costs: evidence from Spanish manufacturing firms

This paper studies the structure of the adjustment costs for heterogeneous labour inputs, allowing for asymmetries and interaction effects among them. To do this, I estimate Euler equations for the demands of permanent nonproduction (white collar) and production (blue collar) employees using a sample of Spanish manufacturing firms. These equations are estimated using the subsample of observations for which adjustment is done, controlling for endogenous sample selection. The main results confirm the heterogeneity of adjustment costs for these two labour inputs, and the existence of cross-adjustment effects between them. Weak evidence of asymmetry in permanent nonproduction labour is also found.     

Farm heterogeneity and technical efficiency: Some results from Swedish dairy farms

This paper introduces farm-heterogeneity in measuring technical efficiency of Swedish dairy farms using farm-level data. In calculating technical efficiency which is allowed to vary over time and across farms, we control for farm-specific effects. This is possible only when panel data is available. Furthermore, we separate technical efficiency from technical change—the presence of which is indicated by a shift in the production function over time,ceteris paribus. We also calculate percentage change in technical efficiency to examine whether farm efficiencies have improved over time. Finally, a comparison of technical efficiency, elasticities of different inputs, and technical change is made across different years and panels. The data includes four panels of dairy farms observed during the period 1976–1988, excluding 1985.We thank two anonymous referees, Anders Klevmarken and Lennart Hjalmarsson for valuable comments.

Socio-demographics,political attitudes and informal sector employment: A cross-country analysis

In this paper, we empirically investigate the relationship between informal sector employment and micro-level socio-demographic characteristics, political acts and attitudes, and individual norms. Using self-reported individual micro-level data from the World Values Survey for seven developing countries (China, Ecuador, Egypt, Mexico, Peru, South Africa and Yemen), our cross-country regressions and principal component analysis reveal that socio-demographic characteristics of individuals are strong predictors of their informal sector employment. Our estimations further document that individual preferences for an economically strong, interventionist and egalitarian state and confidence in state and political institutions are positively and significantly correlated with informal sector employment, whereas variables associated with confidence in free market institutions and support for competition are negatively and significantly correlated with informal sector employment. We also show that individuals who participate either actively or inactively in peaceful and lawful political processes are significantly less likely to work in the informal sector. Finally, we document that individual norms, such as religiosity and tax morale, are negatively correlated with informal sector employment. Throughout our analysis, instead of having to rely on ad-hoc informality categorizations of third parties, we base our measurement of informal sector employment directly on the self-evaluation of individuals, who have the best information on the degree of their informality.     

Local fiscal multipliers and spillover effects: Evidence from Philippine regions

Fiscal policy in developed countries has been a rich topic since the Great Recession. However, research has remained limited for developing countries despite their similar use of fiscal policy and concerns about the efficiency of public spending. To help address this research gap, this paper provides a case study of multiplier effects of local government spending in regions in the Philippines as well as spillover effects of local government spending across regions. An instrumental variable based on the country’s intergovernmental transfer system is used to identify regional public spending in panel regressions. The local fiscal multiplier is estimated to be above one, where a 1-peso rise in spending by local government units in a region corresponds to a 1.2-peso rise in regional output. Multiplier effects are highest for capital expenditures and appear to be primarily driven by the services sector. Spillover effects are comparatively large, at around 1.8–2.0, highlighting the important role of domestic trade when stimulating regional economic activity.     

Chains, holes, and links: Organisation of activities in supplier relationships in the Russian transition economy

In the context of the transition to market economy as a way to accommodate new ways of managing supply, the paper analyses the chain of activities performed in four supplier relationships in the wood-processing industry in Russia. In contrast to what might be expected, the chains of activities in the cases demonstrate different orders of activities, implying that firms tend to organise their chains differently, depending on the character of the relationship. Moreover, the four cases also indicate that activities usually performed by the supplier in Western market economies are still carried out by the customer in Russia. It also seems that the interfaces in the chains are seldom characterised by mutually adapted activities and that the few mutual adaptations observed are to be found at the customer level. Consequently, the activity link between the supplier and the customer tends to be weak; payment and quality control are the only activities that have been adapted to the relationship as such. The paper concludes with a discussion of three strategies for supply management in transition economies.     

Efficiency Measurement With Unbalanced Panel Data: Evidence from Tunisian Textile,Clothing and Leather Industries

This paper is concerned with the estimation of stochastic frontier production functions with unbalanced panel data when unobservable firm efficiency levels are related to explanatory variables. We use the weighted-means Instrumental Variables method acknowledged to R. Gardner (1998) which is a modification of the Hausman-Taylor (1981) procedure adapted for unbalanced panel data. The estimation method is used to examine technical efficiency in Tunisian textile, clothing and leather (TCL) industries during the period 1983–1994. Further, we assume a Translog production frontier where input uses are expressed in efficiency units and adjusted for the age of capital and types of labor. Firm-specific time-invariant technical efficiency is obtained using Schmidt and Sickles (1984) approach. The results suggest that the Instrumental Variables method produces more accurate estimates of the unknown firm level technical efficency. Mean efficency scores resulting from the MHT method is of 66.5%.     

Weber,Marx, and work values: Evidence from transition economies

Are work values a cause (Weber) or consequence (Marx) of the economic environment? The collapse of the Soviet Union at the end of 1991 provides a unique opportunity to investigate this link. Using data collected from an employee survey conducted in over 340 workplaces in Armenia, Azerbaijan and Russia, we investigate generational differences in adherence to the Protestant work ethic (PWE). Our results indicate that Marx was ‘right’ about the link between work values and economic environment. That is, despite economic and cultural differences emerging during the transformation process, in all three countries, participating workers born after 1981 adhere more strongly to PWE than workers born before 1977. Moreover, the estimate magnitudes are very similar across these economically and culturally diverse countries. More generally, PWE adherence is stronger among participating workers with an internal locus of control and among supervisors. PWE adherence also tends to be stronger among participants with high relative earnings, as well as among those working in organizations that reward hard work with the chance to develop new skills or learn new things.     

Home safety,accessibility, and elderly health: Evidence from falls

This article presents estimates of the impact of home safety and accessibility features on the prevention of serious, non-fatal falls for elderly widowed individuals. As these features are not randomly assigned across homes, we develop an instrumental variable (IV) strategy that relies on the differential decline in the health and functional status of spouses to identify impacts. Specifically, we use the deceased spouse’s functional status when alive, as measured by limits to Activities of Daily Living (ADLs), as an IV for the presence of home safety and accessibility features for the surviving spouse in the years after widowhood, and then estimate the effect of these features on the likelihood of a serious fall for the widow using rich longitudinal data from the Health and Retirement Study. The presence of such features reduces the likelihood of a fall requiring medical treatment by 20 percentage points, a substantial effect. However, falls are not the type of health shock that is a main driver of housing tenure transitions among the elderly. Although somewhat speculative, cost–benefit estimates suggest that investments in home safety for the elderly may generate in the short run as much as a dollar-for-dollar reduction in medical expenditures.     

The J-Curve: Evidence from commodity trade between Canada and the U.S.

Several studies in the literature have tried to assess the impact of real depreciation of the Canadian dollar on the Canadian trade balance. They have either relied on the trade data between Canada and the rest of the world or between Canada and her major trading partners. In this paper we consider the trade between Canada and her major trading partner, the U.S. However, unlike previous research, we disaggregate the trade data between the two countries by commodity. We use export and import data over the period 1962–2004 from 152 commodities and the bounds testing approach to cointegration and error-correction modeling and show that real depreciation of the Canadian dollar has short-run effects on the trade balance of two-thirds of the industries. However, only in 50% of the industries, the short-run effects translate into the long-run favorable effects.

Teen employment, poverty, and the minimum wage: Evidence from Canada

In May 2007, the U.S. Congress enacted legislation, which increased the Federal minimum hourly wage from $5.15 to $7.25, over a two year time period. This increase to the minimum wage was the first in nearly a decade and was approved with the objective of alleviating poverty among low-income households. However, a higher minimum wage may result in more unemployment and poverty. We exploit time-series variation in minimum wages set by Canadian provinces between 1981 and 2004. OLS and IV results suggest that a 10% increase in the minimum wage is significantly correlated with a 3%-5% drop in teen employment. Further, a 10% rise in the minimum wage is also significantly associated with a 4%-6% increase in the percentage of families living under Low Income Cut Offs (LICOs). Difference-in-difference estimates from the 1993, 1995, and 1998 waves of the Survey of Consumer Finances (SCF) support these findings as they suggest that income earned by teens constitutes a non-trivial portion of household income for families beneath Low Income Cut Offs. Therefore, a higher minimum wage may paradoxically result in a significant negative shock to household income among low-income families.     

Relative deprivation, relative satisfaction, and attitudes towards immigrants: Evidence from Ukraine

This paper applies the concept of relative deprivation/satisfaction to studying the formation of attitudes towards immigrants. It finds that the feeling of group relative deprivation, as opposed to individual relative deprivation or satisfaction, adversely affects the attitudes of native-born, even when its potential endogeneity is taken into account. Furthermore, relative deprivation matters only for native-born who subjectively underestimate their well-being, but not for those who overestimate it. When considering other forms of native-born individuals’ perceived disadvantage, such as in terms of employment, access to education or medical facilities, there is weak evidence that only a perceived disadvantage in obtaining medical aid negatively affects attitudes.
