Labour unions and leverage: evidence from firm-level union data

ABSTRACT

Using firm-level labour union data from Japan, this paper investigates the effect of labour unions on firm leverage. We find that as union coverage increases, both the level of and extent of change in leverage decreases. These relations remain robust when a firm falls into deficit. We also find that firms with higher union coverage have a higher interest coverage ratio. In addition, we find that firms with higher union coverage are less likely to choose issuing debt compared to issuing equity when they face financial distress. Our results imply that significant employee influence enhanced by labour unions increases fixed costs, crowds out the firm’s debt capacity and consequently reduces the firm’s leverage.     

Pro-poor growth,poverty and inequality in rural Vietnam

This study explores the effects of Vietnam's transition on the welfare of different ethnic groups in rural Vietnam. It draws on three rounds of national household surveys in 2002, 2004 and 2006. It is first observed that the pace of poverty reduction for minorities surpassed the majority over the period 2002–2006, although poor people were still concentrated in the minority groups throughout the period. Secondly, the disparity in living standards has been widening. In particular, inequality within both the majority and minority groups increased over the period. Thirdly, the study shows that the effect of economic growth on poverty is estimated to have been greater if inequality remained constant. It is also noted that the impacts of economic growth on poverty vary across different ethnic groups. Finally, regression decompositions of within inequality have confirmed that the main driver of inequality is not the same among ethnic groups. Given the diversity across different ethnic groups, we can conclude that government policy aimed at equal access to infrastructure and more equal distribution of assets, such as land, for ethnic minority groups would lead to more equal distribution of consumption and poverty reduction of those groups. Also, consideration of local needs would be necessary in designing and implementing public policies, given the heterogeneous socio-economic circumstances surrounding each ethnic minority group.     

A cointegrated commodity pricing model

We propose a commodity pricing model that extends the Gibson–Schwartz two‐factor model to incorporate the effect of linear relations among commodity spot prices, and provide a condition under which such linear relations represent cointegration. We derive futures and call option prices for the proposed model, and indicate that, unlike in Duan and Pliska (2004), the linear relations among commodity prices should affect commodity derivative prices, even when the volatilities of commodity returns are constant. Using crude oil and heating oil market data, we estimate the model and apply the results to the hedging of long‐term futures using short‐term ones.     

Option Values, Switches, and Wages: An Analysis of the Employment Guarantee Scheme in India

Consistent with real option theory, the authors argue that the value of the Employment Guarantee Scheme (EGS) in rural India and its impact on workers' behavior does not depend so much on its income supplementation as on enlargement of opportunities in the uncertain local labor market. The choice between the EGS and other activities is modeled in a dynamic optimization framework, taking into account a fixed wage rate and certainty of employment under the EGS and a stochastic wage rate under other activities. Specifically, volatility of wages in the rural labor markets has important implications for switches into the EGS and for concomitant welfare effects. Under such conditions, the higher the EGS wage, the greater is its attractiveness to relatively skilled and affluent workers, and for those already in it to continue. These and related predictions of the model are validated by panel data estimation.     

Poverty Dynamics of Households in Rural China

The objective of our study is to identify patterns and causes of households' transitions into and out of poverty using the long household panel data on rural China in 1989–2009. We propose a discrete‐time multi‐spell duration model that not only corrects for unobserved heterogeneity, but also addresses the endogeneity due to dynamic selection associated with household's livelihood strategies. The household choosing farming or out‐migration as a main livelihood strategy was more likely to escape from persistent poverty than those taking local non‐agricultural employment. The present study emphasizes the central role of agriculture in helping the chronically poor escape from poverty.     

Poverty,undernutrition and vulnerability in rural India: role of rural public works and food for work programmes

This paper analyses the effects of access to Rural Public Works (RPW) or Food for Work programme (FFW) on consumption poverty, vulnerability and undernutrition in India using the large household data sets constructed by the National Sample Survey for 1993 and 2004. The treatment-effects model is used to take account of sample selection bias in evaluating the effects of RPW in 1993 or FFW in 2004 on poverty. We have found significant and negative effects of participation in RPW and the Food for Work Programme on poverty, undernutrition (e.g. protein) and vulnerability in 1993 and 2004.     

Vulnerability and poverty dynamics in Vietnam

Drawing upon the Vietnam Household Living Standards Survey (VHLSS) data that cover the whole of Vietnam in 2002 and 2004, ex ante measures of vulnerability are constructed. These are then compared with static indicators of poverty (i.e. the headcount ratio in a particular year). Detailed analyses of the panel data show that (i) in general, vulnerability in 2002 translates into poverty in 2004; (ii) vulnerability of the poor tends to perpetuate their poverty and (iii) sections of the nonpoor but vulnerable slip into poverty. Durable reduction in poverty is conditional on (i) accurate identification of the vulnerable, (ii) their sources of vulnerability and (iii) design of social safety nets that would enable the vulnerable to reduce risks and cope better with rapid integration of markets with the larger global economy.     

Microfinance and Household Poverty Reduction: Empirical Evidence from Rural Pakistan

This study examines whether household access to microfinance reduces poverty in Pakistan and, if so, how and to what extent. It draws on primary empirical data gathered by interviewing 1132 households, including both borrower and non-borrower households, in 2008–2009. Sample selection biases have been partially controlled for by using propensity score matching. The study reveals that microfinance programmes had a positive impact on the participating households. Poverty-reducing effects were observed on a number of indicators, including expenditure on healthcare, clothing and household income, and on certain dwelling characteristics, such as water supply and the quality of roofing and walls.
