In the continuing debate over the impact of genetically modified (GM) crops on farmers of developing countries, it is important to accurately measure magnitudes such as farm‐level yield gains from GM crop adoption. Yet most farm‐level studies in the literature do not control for farmer self‐selection, a potentially important source of bias in such estimates. We use farm‐level panel data from Indian cotton farmers to investigate the yield effect of GM insect‐resistant cotton. We explicitly take into account the fact that the choice of crop variety is an endogenous variable which might lead to bias from self‐selection. A production function is estimated using a fixed‐effects model to control for selection bias. Our results show that efficient farmers adopt Bacillus thuringiensis (Bt) cotton at a higher rate than their less efficient peers. This suggests that cross‐sectional estimates of the yield effect of Bt cotton, which do not control for self‐selection effects, are likely to be biased upwards. However, after controlling for selection bias, we still find that there is a significant positive yield effect from adoption of Bt cotton that more than offsets the additional cost of Bt seed. 相似文献

A household model with differential asset endowments and idiosyncratic transactions costs in accessing labor markets is developed to (1) explain membership of farm households to alternative labor regimes (sellers, employers, or self-sufficient in labor), (2) test for recursivity between production and consumption decisions selectively by labor regime, and (3) identify the determinants of differential labor productivity across labor regimes. The model is applied to a 1994 household survey of the Mexican land reform sector. 相似文献

Liberalizing Services Trade In APEC: A General Equilibrium Analysis with Imperfect Competition 总被引:1,自引:0,他引:1
The paper studies services-sector trade liberalization in the Asia–Pacific Economic Co-operation (APEC) Forum using a global, multicountry, multisector applied general equilibrium model with an imperfectly competitive service sector. Reducing the service sector's nontariff barriers is modeled by eliminating the possibility for oligopolistic firms to price-discriminate between client countries within APEC and lowering the fixed costs of the firms doing service exporting business. The results suggest that services trade liberalization reinforces existing sectoral trade balances. Increase in demand for intermediate services tends to reinforce rather than counteract the role of primary factors in determining sectoral comparative advantage. The western APEC members received the greatest welfare gains from services trade liberalization, while the developing economies gained more if only tariffs were eliminated. 相似文献

This article examines the pricing of rental contracts for two types of renter households: those who are able to amass a large, up-front security deposit and those with little, or no, security to offer. Empirical tests are presented to suggest that, in dealing with renter households who have little, or no, security to offer, landlords earn at a similar rate of return as lenders who make riskier loans at a high interest rate to borrowers of dubious credit. The analysis suggests that this situation occurs in large part because of the problem of asymmetric information and moral hazard between landlords and renter households regarding the latter's use of the premises. 相似文献

Using data collected in 2004 from 132 Victorian (Australia) public healthcare providers, comprising metropolitan and regional hospital networks, rural hospitals and community health centres, we investigated the perceptions of HRM from the experiences of chief executive officers, HR directors and other senior managers. We found some evidence that managers in healthcare organisations reported different perceptions of strategic HRM and a limited focus on collection and linking of HR performance data with organisational performance management processes. Using multiple moderator regression and multivariate analysis of variance, significant differences were found in perceptions of strategic HRM and HR priorities between chief executive officers, HR directors and other senior managers in the large organisations. This suggested that the strategic human management paradigm is ‘lost in translation’, particularly in large organisations, and consequently opportunities to understand and develop the link between people management practices and improved organisational outcomes may be missed. There is some support for the relationship between strategic HRM and improved organisational outcomes. Implications of these findings are drawn for managerial practice. 相似文献

Assessing the Impacts of Capital Inflows on Domestic Economy across the Sub-Saharan Africa Countries
Using GMM models, this paper analyzes the impacts of capital inflows on domestic investment in 44 Sub-Saharan Africa (SSA) countries from 2003–2012. It is found that foreign direct investment across the SSA remains to be the largest percentage share, accounting for 35% of the total capital inflows. FDI inflows have significant positive impacts on domestic investment across the SSA in both short term and long term. Other key macroeconomic factors such as age dependency ratio, domestic economic growth, terms of trade, real effective exchange rate and trade openness also play vital roles in determining domestic investment. 相似文献

Modeling the price of multi‐attribute products generally requires an assessment of each attributes' market value. In the presence of price dispersion, when similar products are sold at different prices, hedonic pricing models provide users with biased estimates of attribute value. This paper develops the hedonic pricing literature by proposing data envelopment analysis as a prior means of identifying a sub‐sample of products which, after adjusting for attribute provision, display no price dispersion. These products then display a homogenous link between attributes and price, which can be modeled using hedonic pricing. This paper implements and evaluates this two‐stage approach using 1000 observations from the UK mortgage market. Copyright © 2014 John Wiley & Sons, Ltd. 相似文献
