Vertical integration and investor protection in developing countries

The industrial organization of developing countries is characterized by the pervasive use of subcontracting arrangements among small, financially constrained firms. This paper asks whether vertical integration relaxes those financial constraints. It shows that vertical integration trades off the benefits of joint liability against the costs of rendering the supply chain more opaque to external investors. In contrast to the commonly held view that pervasive input and capital market imperfections are conducive to vertical integration, the model predicts that the motives for vertical integration are not necessarily higher in developing countries. In particular, vertical integration is more likely to arise at intermediate levels of investor protection and better contract enforcement with suppliers reduces vertical integration only if financial markets are sufficiently developed. Evidence supporting both predictions is discussed.     

Microfinance and competition for external funding

In this paper we examine a one-period model in which poverty minimizing microfinance lenders must raise external funding from a profit maximizing investor. Assuming that the lenders vary in their operating costs, we find that competition between lenders for external funds can lead to higher aggregate poverty reduction.     

How Do Banks Determine Capital? Evidence from Germany

Abstract. We analyse whether the determinants of capital found in the previous literature hold for the special German banking sector comprising three characteristic banking groups including savings banks, cooperative banks and other banks, which differ regarding their ownership and their access to the capital market. Through the use of accounting data from German banks between 1992 and 2001 we find evidence in accordance with the buffer theory of capital for all German banking groups. Furthermore, we also detect some remarkable differences between the three banking groups regarding their determination of capital due to institutional characteristics.     

Estimates of gender differences in firm’s access to credit in Sub-Saharan Africa

Based on firm level data from 16 Sub-Saharan African countries we show how three different measures of credit constraints lead to three different estimates of gender differences in manufacturing firms’ credit situation. Using a perception based credit constraint measure female owned firms appear relatively more constrained than male owned firms. Using formal financial access data we find no gender effect. Finally, using direct information on credit constraints, male owned small firms appear disadvantaged. Furthermore we show a strong size gradient in the gender gap for the two measures for which we find significant gender differences.     

Dynamic effects of trade openness on financial development

This paper employs the Pooled Mean Group (PMG) approach of Pesaran et al. (1999) to study the dynamic effects of trade openness on financial development. The advantage of the PMG estimator over other dynamic panel econometric techniques is that it allows short-run coefficients, speeds of adjustment and error variances to vary across countries, with cross-country homogeneity restrictions only on long-run parameters. Our results spanning 88 countries over 1960–2005 show that a positive long-run relationship between trade openness and financial development coexists with a negative short-run relationship. But when splitting the data into different income or inflation groups, this finding is observed only in relatively low-income countries or high-inflation economies.     

Corporate Governance and Financial Performance of Companies in Poland

The research presented in the paper is aimed at examining the relationship between the level of corporate governance and the financial performance of listed companies in Poland. The corporate governance degree is expressed by the outcomes of a rating of 2003 performed by Polish Corporate Governance Forum. The attempted models are of ordered multinomial type. Endogenous variable represents the rating outcome (A−, B+, B, B−, and C+), while the exogenous variables include various financial indicators evaluated on the basis of the 2002 financial statements. The estimated ordered logit models show that the level of corporate governance of companies in Poland is associated with their ability to cope with the financial distress, as expressed by the degree of liquidity, profitability and the financial leverage variables.     

Health care expenditure and economic growth: Quantile panel-type analysis

This study uses international total health care expenditure data of 31 countries from 1986 to 2007 for exploring the causality between an increase in health care expenditure and economic growth. The empirical procedure is divided into two parts. The first is the panel regression analysis and the second is the quantile regression analysis. The estimation of the panel regression reveals that, expenditure growth will stimulate economic growth; however, economic growth will reduce expenditure growth. With regard to the estimation of quantile regression, when economic growth is quantile, in countries with low level of growth, the influence of expenditure growth on economic growth is different. In countries with medium and high levels of economic growth, the influence of expenditure growth on economic growth is positive; when health care expenditure growth is quantile, the influence of economic growth on expenditure growth is more different.     

Health shocks and consumption smoothing in rural households: Does microcredit have a role to play?

This paper estimates, using a large panel data set from rural Bangladesh, the effects of health shocks on household consumption and how access to microcredit affects households’ response to such shocks. Households appear to be fairly well insured against health shocks. Our results suggest that households sell livestock in response to health shocks and short term insurance is therefore attained at a significant long term cost. However microcredit has a significant mitigating effect. Households that have access to microcredit do not need to sell livestock in order to insure consumption. Microcredit organizations and microcredit therefore have an insurance role to play, an aspect that has not been analyzed previously.     

Subcontractors for tractors: Theory and evidence on flexible specialization,supplier selection,and contracting

Buyer–Seller networks are pervasive in developing economies yet remain relatively understudied. Using primary data on contracts between the largest tractor assembler in Pakistan and its suppliers we find large variations in prices and quantities across suppliers of the same product. Surprisingly, “tied” suppliers – those that choose higher levels of specific investments – receive lower and more unstable orders and lower prices. These results are explained by developing a simple model of flexible specialization under demand uncertainty. A buyer faces multiple suppliers with heterogeneous types to supply customized parts. Specific investments raise surplus within the relationship but lower the seller's flexibility to cater to the outside market. Higher quality suppliers have a greater likelihood of selling outside and so this cost is greater for them. Therefore even if a buyer typically prefers high types, some low type suppliers might be kept as marginal suppliers because of their greater willingness to invest more in buyer-specific assets. Further empirical examination shows that the more tied suppliers are indeed of lower quality.     

AIDS and economic growth: A human capital approach

Using a model that combines growth and health capital equations this study analyses the impact of HIV/AIDS on economic growth. The econometric results indicate that the epidemic's effects have been substantial; in Africa the marginal impact on income per capita of a 1% increase in HIV prevalence rate is minus 0.59%. Even in countries with lower HIV prevalence rates the marginal impacts are non-trivial. Hence while the human and social costs of the HIV/AIDS epidemic are major causes for concern, these results indicate that the macroeconomic affects of the HIV/AIDS epidemic are important.     

TRIPs and patenting activity: Evidence from the Indian pharmaceutical industry

This paper studies the impact of the strict patent regime on the patenting activity of Indian pharmaceutical firms and finds that patenting activity of these firms has increased after the signing of TRIPs. The study is conducted for 65 pharmaceutical firms for the period 1991 to 2004 using different parametric and semiparametric count panel data models. Results across different count data models indicate a positive and significant impact of the introduction of stronger patents on patenting activity. Further, the results show a gestation lag of 2 years between R&D spending and patent applications.     

Estimation of conditional time-homogeneous credit quality transition matrices

This paper presents a methodology for estimating time-homogeneous credit quality transition matrices. Using a unique data set on credit ratings of commercial loans in Colombia, we show that 70% of the time we cannot reject the null hypothesis of time homogeneity of transition matrices estimated this way. We also find that obtaining matrices for different subsamples is not necessary, given the similarities of the survival functions.     

Economic integration and the profitability of cross-border mergers and acquisitions

The 1990s was a decade of increased economic integration. The decade also witnessed a sharp increase in cross-border mergers and acquisitions. From a theoretical perspective, the increase in international mergers in more integrated economies is rather puzzling. It is a well-established result that due to the “business stealing effect”, mergers in integrated markets are not likely to be profitable. A reasonable conjecture would therefore be that closer integration of markets would reduce the attractiveness of cross-border mergers and acquisitions. The present paper demonstrates that this is not necessarily the case: Economic integration may trigger cross-border acquisitions by reducing the business stealing effect and by reducing the reservation price of the target firm. The paper thus provides explanations to the observed increase in cross-border mergers in a world of more integrated economies.
