Corruption,Bureaucracy and Firm Productivity in Africa

This paper estimates the impact of corruption and poor bureaucratic quality on firm productivity for a unique dataset with firm‐specific data of more than 900 firms over 12 years for Ghana, Kenya and Tanzania. We first discuss why poor bureaucratic quality and, especially, corruption are expected to have negative impacts on firm productivity. We then employ Data Envelopment Analysis to estimate firm productivity and pooled OLS and Tobit regression analysis to estimate the effects of corruption and bureaucratic quality on firm productivity. We find that less productive firms are more likely to engage in corrupt activities; both poor bureaucratic quality and corruption reduce firm productivity; and corruption has a greater negative impact on productivity.     

Can Micro Health Insurance Reduce Poverty? Evidence From Bangladesh

This article examines the impact of micro health insurance on poverty reduction in rural areas of Bangladesh. The research is based on household‐level primary data collected from the operating areas of the Grameen Bank during 2006. A number of outcome measures are considered; these include household income, stability of household income via food sufficiency and ownership of nonland assets, and the probability of being above or below the poverty line. The results show that micro health insurance has a positive association with all of these indicators, and this is statistically significant and quantitatively important for food sufficiency.     

Combating the English language deficit: the labour market experiences of migrant women in Australia

This article takes a multilevel perspective on the labour market issues and challenges that migrant women from non‐English speaking backgrounds (NESB) encounter in Australia. The article is based on two main arguments: (1) a much more complex picture emerges when we look at the intersection of gender, ethnicity, and migration, and its implications for the labour market experiences of NESB women and (2) single level conceptualisations of diversity management within the domain of organisational or legal policies are inadequate to address the multilevel challenges faced by NESB women. The article presents a qualitative study in which we theorise our findings through a multilevel construct, examining the macro‐national, meso‐organisational, and micro‐individual challenges that NESB women, originating from Afghanistan, Iran, and Pakistan, face in the Australian labour market.     

Bank efficiency in South‐Eastern Europe

This study examines the cost and profit efficiency of banking sectors in six transition countries of South‐Eastern Europe over the period 1998–2008. Using a stochastic frontier approach, our analysis reveals that the average cost efficiency of South‐Eastern European banks is 68.59 percent, and the average profit efficiency is 53.87 percent. Regressions on the determinants of bank efficiency show that foreign banks are characterized by higher profit efficiency but lower cost efficiency, and government‐owned banks are associated with lower profit efficiency than domestic private banks. However, the efficiency gap between foreign‐, domestic private‐ and government‐owned banks narrows over time. We also find that the market power of a bank has a positive association with both cost and profit efficiency. Institutional development, proxied by progress in banking regulatory reforms, privatization and enterprise corporate governance restructuring, also has a positive impact on bank efficiency.     

Do investment in and the sourcing arrangement of the internal audit function affect audit delay?

This paper investigates the association between the internal audit function attributes and audit delay using a sample of 432 publicly traded firms in Malaysia in 2009. In this unique setting, we capitalize on the publicly available data concerning the investment in and the sourcing arrangement of internal audit function. We find a negative relationship between the costs incurred for the internal audit function and audit delay. However, we do not find any significant association between the internal audit function sourcing arrangements and audit delay. Additionally, we find that greater audit committee independence and longer auditor–client tenure shorten audit delay, and more frequent audit committee meetings and higher misstatements in the preliminary unaudited earnings are associated with a longer audit delay.     

Panel cointegration and the monetary exchange rate model

This paper re-examines the validity of the monetary exchange rate model during the post-Bretton Woods era for 18 OECD countries. Our analysis simultaneously considers the presence of both cross-sectional dependence and multiple structural breaks, which have not received much attention in previous studies of the monetary model. The empirical results indicate that the monetary model emerges only when the presence of structural breaks and cross-country dependence has been taken into account. Evidence is also provided suggesting that the breaks in the monetary model can be derived from the underlying purchasing power parity relation.     

Intraday Seasonalities and Macroeconomic News Announcements

Using a data set consisting of more than five years of 5‐minute intraday stock index returns for major European stock indices and US macroeconomic surprises, conditional means and volatility behaviour in European markets were investigated. The findings suggest that the opening of the US stock market significantly raises the level of volatility in Europe, all markets responding in an identical fashion. Furthermore, US macroeconomic surprises exert an immediate and major impact on both the European stock markets’ intraday returns and volatilities. Thus, high frequency data appear to be critical for the identification of news impacting the markets.     

Market discipline during crisis: Evidence from bank depositors in transition countries

The Central European banking industry is dominated by foreign-owned banks. During the recent crisis, for the first time since the transition, foreign parent companies were frequently in a worse financial condition than their subsidiaries. This situation created a unique opportunity to study new aspects of market discipline exercised by non-financial depositors. Using a comprehensive data set, we find that the recent crisis did not change the sensitivity of deposit growth rates to accounting risk measures. We establish that depositors’ actions were more strongly influenced by negative press rumors concerning parent companies than by fundamentals. The impact of rumors was especially perceptible when rumors turned out ex post to be founded. Additionally, we document that public aid announcements were primarily interpreted by depositors as confirmation of a parent company’s financial distress. Our results indicate that depositors react rationally to sources of information other than financial statements; this discovery has policy implications, as depositor discipline is usually the only viable and universal source of market discipline for banks in emerging economies.
