Does Zero Tillage Improve the Livelihoods of Smallholder Cropping Farmers?

The biophysical benefits of zero tillage (ZT) are well documented in the literature. However, the literature on its economic benefits, especially in the context of small and medium‐scale farmers in the temperate developing world is scanty. Using a study of 621 wheat farmers in Syria, we provide empirical evidence on the impacts of adoption of ZT on farm income and wheat consumption. We use propensity score matching (PSM) and endogenous switching regression (ESR) approaches to account for potential selection biases. After controlling for confounding factors, we find that adoption of the ZT technology leads to a US$ 189/ha (33%) increase in net crop income and a 26 kg (34%) gain in per capita wheat consumption per year (adult equivalent) – an indication of meaningful changes in the livelihoods of the farm households. Besides the biophysical and environmental benefits documented elsewhere, our results suggest that adoption of ZT can also be justified on economic and food security grounds. Therefore, ZT can have sizeable impacts in transforming the agricultural sector in the temperate developing world provided that the technology is well promoted and adopted.     

Teenager–peer interaction and its contribution to a family purchase decision: the mediating role of enduring product involvement

The influencing roles of teenager–peer interaction and enduring product involvement on a teen's contribution to a family purchase decision are examined using survey data from 1008 Tunisian teens. Results demonstrate that enduring product involvement mediates the relationship between teenager–peer interaction and the teenager's contribution. A structural equation model with supporting Bootstrap procedure is presented. Implications, limitations and suggestions for future research are discussed.

Libéralisation financière,développement financier et croissance économique: Nouvelle évidence empirique

Résumé: La relation entre le développement financier et la croissance économique a suscité beaucoup d’attention ces dernières années dans la littérature économique. Dans ce papier, nous avons présenté, en premier lieu, l’effet du développement bancaire sur la croissance économique à travers une validation empirique en données de panel d’un modèle à effets aléatoires de 52 pays de 1980 à 2005, et en second lieu, nous avons essayé d’explorer les liens qui peuvent exister entre le développement financier au sens large (bancaire et boursier) et la croissance économique à travers une analyse en coupe transversale pour 42 pays durant la période 1988–2002. Les principaux résultats retenus de ce travail montrent que le niveau du développement financier au sens large peut être un facteur important pour la croissance économique. Toutefois, force est de signaler que cette contribution est conditionnée par la réunion de certaines conditions.     

The Impact of Fixed Exchange Rates on Fiscal Discipline

In this paper, it is shown that contrary to standard arguments, fiscal discipline is not substantially enhanced by a fixed exchange rate regime. This study is based on data from 116 countries collected from 1975 to 2004, and uses various estimation techniques for dynamic panel data, in particular a generalized method of moments estimation in the tradition of Arellano and Bover [Journal of Econometrics (1995), 68 , 29] and Blundell and Bond [Journal of Econometrics (1998), 87 , 115]. Contrary to previous papers on this topic, the present paper takes into account that the consequences of a new exchange rate regime do not necessarily fully manifest immediately.     

Market and Model Credit Default Swap Spreads: Mind the Gap!

Structural models of default establish a relation across the fair values of various asset classes (equity, bonds, credit derivatives) referring to the same company. In most circumstances such relation is verified in practice, as different financial assets tend to move in the same direction at similar speed. However, occasional deviations from the theoretical fair values occur, especially in times of financial turmoil. Understanding how the dynamics of the theoretical fair values of various assets compares to that of their market values is crucial to a number of market participants. This paper investigates whether a popular structural model, the CreditGrades approach proposed by Finger (2002) , Stamicar and Finger (2005) , succeeds in explaining the dynamic relation between equity/option variables and Credit Default Swap (CDS) premia at individual company level. We find that CDS model spreads display a significant correlation with CDS market spreads. However, the gap between the two is time varying and widens substantially in times of financial turbulence. The analysis of the gap dynamics reveals that this is partly due to episodes of decoupling between equity and credit markets, and partly due to shortcomings of the model. Finally, we observe that model spreads tend to predict market spreads.     

Does corporate social responsibility affect the cost of capital?

We examine the effect of corporate social responsibility (CSR) on the cost of equity capital for a large sample of US firms. Using several approaches to estimate firms’ ex ante cost of equity, we find that firms with better CSR scores exhibit cheaper equity financing. In particular, our findings suggest that investment in improving responsible employee relations, environmental policies, and product strategies contributes substantially to reducing firms’ cost of equity. Our results also show that participation in two “sin” industries, namely, tobacco and nuclear power, increases firms’ cost of equity. These findings support arguments in the literature that firms with socially responsible practices have higher valuation and lower risk.     

Nonstationarity and Stochastic Stability of Relative Income Clubs

The recent literature on “convergence” of cross‐country per capita incomes has been dominated by the two hypotheses of “global convergence” and “club‐convergence,” pertaining to limits of estimated income distribution dynamics. Utilizing a new measure of “stochastic stability,” we establish two stylized facts regarding short‐ and medium‐term distribution dynamics. The first is non‐stationarity of transition dynamics, in the sense of changing transition kernels, and the second is emergence, disappearance, and re‐emergence of a “stochastically stable” middle income group. This middle income group emerges as the gap between rich and poor clubs gets larger, and it changes the dynamics of transition to and from the rich and poor clubs, eventually narrowing the gap between the poor and rich as the middle club vanishes. Analyzing the stochastic stability of middle‐income groups is thus a first step toward understanding higher‐order dynamics of narrowing or widening of the gap between rich and poor countries.
