Technological Adaptation, Trade, and Growth. — Based on Grossman and Helpman’s 1991 seminal work, the authors provide a simple
model extension where innovations created in the high-tech sector may be assimilated or adapted by the lowtech sector, thus
generating nondecreasing returns in the production function of the latter. When applying a Heckscher-Ohlin framework the authors
find that the effects of technological diffusion allow a country relatively scarce in human capital to benefit from nondecreasing
rates of growth through its low-tech sector. They test this idea by using a dynamic panel data approach in order to deal with
simultaneity and country heterogeneity. Their results are consistent with the predictions of the model and robust to a broad
range of definitions of technological intensity. 相似文献

Normalized interindustry wage differentials à la Krueger and Summers [Krueger, A.B., Summers, L.H., 1988. Efficiency wages and the inter-industry wage structure. Econometrica 56, 259–293] derive from a general specification of wage equations with dummy variables which cannot be directly estimated. This note illustrates how they can be obtained from the coefficients of a more specific parameterization and how their estimated variances can be transformed accordingly. 相似文献

Proceeding from three basic concepts of resource dependence theory – organizational effectiveness, interdependence and external control – we conducted a multiple‐case study to investigate factors that facilitate and hinder sustainability management within supply chains. Our empirical observations highlight that focal firms do not necessarily transfer their own corporate sustainability agendas into control mechanisms for managing the sustainability of their suppliers. Based on this insight, we develop a new theory that explains how intra‐ and interorganizational sustainability management is affected by a firm's business case for promoting sustainability, control mechanisms, trade‐offs, trust and market liberalization. The theory offers new insights into drivers and barriers for effective interorganizational sustainability management, whereas previous theories could not fully explain the reasons for diverging sustainability management practices in supply chains.

Despite mandatory parental leave policies being a prevalent feature of labor markets in developed countries, their aggregate effects in the economy are not well understood. To assess their quantitative impact, we develop a general equilibrium model of fertility and labor market decisions that builds on the labor matching framework of Mortensen and Pissarides (1994). We find that females gain substantially with generous policies but this benefit occurs at the expense of a reduction in the welfare of males. Leave policies have important effects on fertility, leave taking decisions, and employment. These effects are mainly driven by how the policy affects bargaining – young females anticipate future states with higher threat points induced by the policy. Because the realization of these states depends on the decisions of females to give birth and take a leave, leave policies effectively subsidize fertility and leave taking. We also find that generous paid parental leaves can be an effective tool to encourage mothers to spend time with their children after giving birth. 相似文献

Summary. This paper studies the effects of uncertain lifetime on capital accumulation and growth and also the sensitivity of those
effects to the existence of a perfect annuities market. The model is an overlapping generations model with uncertain lifetimes.
The technology is convex and such that the marginal product of capital is bounded away from zero. A contribution of this paper
is to show that the existence of accidental bequests may lead the economy to an equilibrium that exhibits asymptotic growth,
which is impossible in an economy with a perfect annuities market or with certain lifetimes. This paper also shows that if
individuals face a positive probability of surviving in every period, they may be willing to save at any age. This effect
of uncertain lifetime on savings may also lead the economy to an equilibrium exhibiting asymptotic growth even if there exists
a perfect annuities market.

This editorial summarises the papers published in issue 13.1 so as to raise the bar in applied spatial economic research and highlight new trends. The first paper adopts a scale neutral approach to investigate the spatial mechanisms that cause regional innovation and growth. The second paper claims that population-weighting when calculating indices of regional inequality might lead to inconsistent outcomes. The third paper estimates the effect of distance between family residence and higher education institution on a student's academic performance, thereby accounting for endogenous regressors. The fourth paper shows an inverted U-shaped relationship between economic development at region of origin and the propensity to migrate using a multilevel approach. The fifth paper provides spatial econometric evidence of price competition between sellers of used books on Amazon.com. The last paper estimates a hedonic housing price equation and parameterizes the spatial weight matrix to determine how far back in time buyers, sellers and realtors are looking at the housing market. 相似文献

Resume ** : Dans la plupart des pays en développement, la relative rareté de l'eau s'accompagne d'une détérioration continue de sa qualité. L'article propose quelques réflexions sur l'implication du secteur privé dans la gestion de l'approvisionnement en eau dans les pays en développement. L'analyse se centre principalement sur les implications sociales et les limites afin de vérifier si la privatisation contribue à l'élargissement de l'accès à l'eau. A cette fin, plusieurs exemples de cas sont présentés qui étayent les conclusions présentées dans la dernière section de l'article . 相似文献
