Financial development,financial liberalization and social capital

The relationship between financial liberalization policies and financial development is controversial. The impact of these policies differs greatly across countries. In the literature, the quality of formal institutions has been identified as an important source of this heterogeneity, as countries with a weak institutional environment generally fail to benefit from financial liberalization. Using panel data covering 82 countries for the period 1973–2008, we find evidence that social capital may substitute for formal institutions as a prerequisite for effective financial liberalization policies. In particular, we find that during the post Washington-consensus period countries with a high prevailing level of social capital can ensure that financial liberalization positively influences financial development, despite the poor quality of their formal institutions.     

Separability and capital aggregation in sectoral models of US production

Separability plays a fundamental role in applied studies of production inasmuch as it provides for consistent aggregation and allows multi-stage estimation of models with many inputs. This paper examines whether two types of capital, structures and equipment, are weakly separable from labour and energy and materials in sectoral models of US production, and provides an assessment of the effects of maintaining capital separability. The study focuses on the elasticity of substitution as a measure of input association and associated standard errors and confidence intervals based on bootstrapping. Elasticity estimates and tests indicate that capital separability is generally inconsistent with data representing sectoral US production. Elasticity sign, however, appears robust to capital aggregation and performs especially well as an indicator of input association.     

Human capital, market imperfections, and labor reallocation in transition

In this paper, we investigate the effects of human capital and factor market imperfections on household decisions regarding labor use and reallocation in transition countries. We develop a model that accounts explicitly for heterogeneity in the supply of labor and analyze its impact on the allocation of labor. Furthermore, the effects of imperfections in the capital and labor markets on the reallocation process are modeled. Using a dataset based on a countrywide representative survey of Hungarian rural households, we estimate the effects empirically and find them to be important.

Financial liberalization and the relationship-specificity of exports

We investigate the causal impact of equity market liberalizations on sectoral export performance across 91 countries (1980–1997). The increased availability of external finance has boosted trade of industries that intensively use relationship-specific inputs, and lowered exports of industries using standardized inputs.     

Financial liberalization and short-run housing price dynamics

We develop a continuous time, rational expectations, multi-cohort model of an exchange economy with housing, the purchase of which is subject to a down payment (DP) constraint. The timing of the house purchase decision is a crucial endogenous variable, and four determinants of it are identified – the housing services effect, the interest discounting effect, the consumption smoothing effect, and the rate of price increase effect. Cohort effects, and supply constraints, play crucial roles at the aggregative level. We explore in detail the effects of a discrete financial liberalization, and show that if the liberalization is not announced sufficiently far in advance, housing prices will initially overshoot the new stationary equilibrium, and vice versa. Particular attention is paid to the possibility that for a subset of cohorts along the transition path the DP constraint will not bind.

Financial development, liberalization and technological deepening

This paper focuses on examining the effects of financial development and liberalization on knowledge accumulation. The results consistently show that while financial development facilitates the accumulation of new ideas, the implementation of financial reform policies is negatively associated with it. The undesirable effects of financial liberalization are found to operate through the triggering of crises and volatility in the financial system. There is also evidence supporting the hypothesis that financial liberalization reallocates talent from the innovative sector to the financial system, thus retarding technological deepening. Moreover, the findings also suggest that increased R&D activity and the presence of a stronger intellectual property rights protection framework tend to have beneficial effects on knowledge accumulation.     

Financial liberalization and the stationarity of money multiplier

Abstract

In countries without an explicit inflation targeting mechanism, a stable relationship between the monetary base and the money supply allows policymakers to implement changes in monetary policy with a reasonable degree of certainty about the impact on the money supply. The relationship can, however, be influenced by major structural shifts such as financial sector reforms. The present study finds that when structural change bought about by financial liberalisation is ignored, the unit root hypothesis is spuriously accepted. However, once this break is incorporated into the analysis, the multiplier exhibits no presence of a stochastic trend.     

Long-term impact of trade liberalization on human capital formation

While a growing line of research has assessed the effect of trade liberalization on human capital formation, most of these studies focus on its short-term effect on individual’s school attendance. Much less is known about its long-run effect, as well as the impact on other aspects of human capital formation such as labor market and noncognitive outcomes. This paper studies the impact of trade liberalization on individuals’ long-term human capital accumulation, including school attendance, cognitive abilities, labor market performance, and noncognitive outcomes. By constructing prefecture-year-level tariff barriers, our identification strategy exploits variations in different cohorts’ exposure to a trade shock at age 16 for individuals within the same prefecture. Empirical results suggest that trade liberalization leads to decreased completed years of schooling, cognitive abilities, wage, and noncognitive outcomes. We provide suggestive evidence that this observed pattern is explained by the expansion of job opportunities in relatively low-skilled and labor-intensive sectors.     

Addressing causality in the effect of capital account liberalization on growth

Evidence supporting the positive effects of capital account liberalization on growth is mixed at best. Even after conditioning on the quality of domestic financial institutions, a significant number of studies still find no effect. One possible explanation is reverse causation. If low growth countries liberalize in order to spur growth, the observed correlation between growth and liberalization will underestimate the impact of capital account openness. To eliminate this bias, I instrument capital account liberalization with the average level of openness of other countries to capture the “fad” element in financial liberalization. IV estimates indicate a significant positive effect of liberalization on growth, confirming the predictions of economic theory.

Inflation and growth in South Africa

This paper studies the relationship between inflation and growthin South Africa. Two main issues are addressed: do tests ofthe South African data support the findings of cross-sectionstudies that inflation has a negative effect on growth overthe longer term? and, can higher growth be gained at the costof higher inflation in the short run? The findings are thatinflation drags down growth in South Africa over the longerterm, and that, in the short run, growth above its trend requiresaccelerating inflation. Thus, for growth to be pulled substantiallyabove its present low trend, inflation targeting in South Africawould have to be abandoned. However, this would be counterproductiveover the longer term, once the negative relationship betweeninflation and growth manifests itself.     

Financial liberalization and bank efficiency: a comparative analysis of India and Pakistan

This paper provides a comparative analysis of the evolution of the technical efficiency of commercial banks in India and Pakistan during 1988–1998, a period characterized by far-reaching changes in the banking industry brought about by financial liberalization. Data Envelopment Analysis is applied to two alternative input–output specifications to measure technical efficiency, and to decompose technical efficiency into its two components, pure technical efficiency and scale efficiency. The consistency of the estimated efficiency scores are checked by examining their relationship with three traditional non-frontier measures of bank performance. In addition, the relationship between bank size and technical efficiency is examined. It is found that the overall technical efficiency of the banking industry of both countries improved gradually over the years, especially after 1995. Unlike public sector banks in India, public sector banks in Pakistan witnessed improvement in scale efficiency only. It is also found that banks are relatively more efficient in generating earning assets than in generating income. This is attributed to the presence of high non-performing loans. In addition, it is found that the gap between the pure technical efficiency of different size groups has declined over the years.     

Financial Development and Income in North Africa

We explore the short-run dynamics and long-run relationship between income and financial development in Algeria, Egypt, and Morocco. We use co-integration and VECM models and four indicators of financial development. The empirical results indicate that there is a long-run relationship between income and each financial development indicator, except credit to the private sector in Algeria. On the other hand, Granger-causality test results indicate that the evidence on the direction of causality is mixed.

Earnings inequality and unemployment in South Africa

Unemployment and earnings inequality have moved together remarkably closely in South Africa in recent years. This article explores the relationship between unemployment and earnings inequality in South Africa, investigating the extent to which changes in unemployment can account for changes in earnings inequality. Static and dynamic decompositions of earnings inequality by employment status reveal the centrality of unemployment in accounting for the both level and trend of earnings inequality. The distribution of employment in the formal and informal sectors is found to be of lesser importance in explaining earnings inequality, as is wage dispersion within each of these categories. The findings point to the central importance of reducing unemployment in South Africa if the extremely high levels of inequality are to be reduced.     

Legacy and credit scores in South Africa

This paper assesses the impact of legacy and credit scores on access to bank credit in South Africa. Typically, credit data focuses on socio-economic information. However legacy variables, factors beyond the control of individuals, have not been well considered. We find that although credit scores clearly influence access to credit, legacy has a statistically significant impact on credit scores and on the amount of credit granted. While these results can be interpreted as bias against those with negative legacy, they can also be explained in terms of information asymmetry and the relative ability to enforce contracts with clients who have positive legacy.     

Private capital inflows and stock market interface in sub-Saharan Africa

The financial market school of thought argues that financial market plays a key role in facilitating capital flows to less developed countries of the world. This school considers stock market a strong and potent channel of attracting and mobilizing capital for development across the globe. The study in this paper is therefore undertaken to determine the validity of this argument, by investigating how the stock market interfaces with other variables to influence capital flows to sub-Saharan Africa. The empirical evidence clearly validates the importance of stock market by showing its direct positive impact on all the components of private capital inflows, an impact that is significantly enhanced by return on investment in the market. The stock market is also revealed to have a maximum threshold that suggests it possesses the capacity to channel a significant proportion of potential capital inflows. These findings point to the importance of raising the level of stock market development in order to attract more capital flows to the region, and indeed the less developed regions of the world.     

The impact of financial liberalization on capital structure adjustment in Pakistan: a doubly censored modelling

The purpose of the study is to explain adjustment rate towards target capital structure of Pakistani nonfinancial listed firms and to investigate the impact of financial liberalization (FL) on capital structure adjustment rate. We control for the unobserved heterogeneity and the fractional nature of adjustment rate by applying an unbiased dynamic panel fractional estimator on an unbalanced panel data of Pakistani nonfinancial firms listed during 1972–2010. We find that these firms adjust at an annual rate of 24–51% to reach their capital structure targets. We argue that in order to optimize the benefits of FL the government should strengthen financial as well as judicial institutions to enforce the creditors’ rights that will enable access to more options to Pakistani firms to raise cheaper external financing.
