Exit rates from unemployment and re‐employment wages decline over a period of unemployment, after controlling for worker observable characteristics. We study the role of unobserved heterogeneity in an economy with asymmetric information and directed search. We show that the unique equilibrium is separating and that skilled workers have more job opportunities and higher wages. The composition of the unemployed varies with the duration of unemployment, so average exit rates and wages fall with time. The separating equilibrium relies on performance‐related pay schemes and the ability of firms to commit to renting an input that is complementary to worker skills.  相似文献

The volume of cash-flow transformation activities has grown markedly over the past few decades. We develop a dynamic model that characterizes the effects of changes in the costs and benefits of security creation. Lower tranching costs and increases in foreign appetite for safe assets can both increase costly security creation with positive effects on GDP and have diverse macroeconomic implications. Whereas the former counterfactually increases yields, the latter lowers them and also raises rents associated with cash-flow transformation. These two features, as well as other subsidiary implications of increased foreign demand, are consistent with recent U.S. data.  相似文献

This paper analyses efficiency drivers of a representative sample of Spanish football clubs by means of the two-stage data envelopment analysis (DEA) procedure proposed by Simar and Wilson (J Econ, 136:31–64, 2007). In the first stage, the technical efficiency of football clubs is estimated using a bootstrapped DEA model in order to establish which of them are the most efficient; the ranking is based on total productivity in the period 1996–2004. In the second stage, the Simar and Wilson (J Econ, 136:31–64, 2007) procedure is used to bootstrap the DEA scores with a truncated bootstrapped regression. Policy implications of the main findings are also considered.  相似文献

In Portugal, until recently, the telecommunications incumbent offered broadband access to the Internet, both through digital subscriber line and cable modem. We estimate the impact on broadband access to the Internet of the structural separation of these two businesses. Using a panel of consumer level data and a random effects mixed logit model, we estimate the price elasticities of demand and the marginal costs of broadband access to the Internet. Based on these estimates, we simulate the effect of structural separation on prices and social welfare. Our estimates indicate that structural separation would cause a substantial welfare increase. These results raise questions about the policy of some countries of allowing the dual ownership of telephone and cable networks.  相似文献

This article studies the impact of publicly subsidized agricultural extension services on yields and product quality. We use panel data from grape producers in Mendoza, Argentina to estimate the impacts of farmer trainings. We find a negative overall impact on yields and evidence of a positive average impact on the adoption of higher‐quality grape varieties. By analyzing the dynamic pattern of the estimated effects, we find evidence of a temporary decrease in yields suggesting the existence of an adjustment process following the introduction of higher‐quality grapes. The overall negative effect on yield is driven by a sharp drop in the year of participation. This fades after year one, and two to three years after treatment we observe increases in higher‐quality grape production. Findings reinforce the importance of temporal dimension of extension services.  相似文献

Real exchange rate movements are important drivers of the reallocation of resources between sectors of the economy. Economic theory suggests that the impact of exchange rates should vary with the degree of exposure to international competition and with the technology level. We show that both the degree of openness and the technology level mediate the impact of exchange rate movements on labour market developments. According to our estimations, whereas employment in high-technology sectors seems to be relatively immune to changes in real exchange rates, these appear to have sizable and significant effects on highly open low-technology sectors. The analysis of job flows suggests that the impact of exchange rates on these sectors occurs through employment destruction.  相似文献

The creation of new knowledge is a case in which agents' behaviour can affect the performance of other actors positively, given that new knowledge creates positive externalities in the market. In this context, we investigate the existence of performance spillovers associated with innovation activities by quantifying the innovation produced in surrounding firms and controlling for the fact that a firm is itself an innovation producer. We use data from the Third Community Innovation Survey (CIS III) that measures innovation in a broad way, not reducing it to R&D and patents, which departs from previous literature on spillovers. Furthermore, to tackle the endogeneity of the innovation variables on the firm production decision, we resort to the firm intellectual property protection methods as an instrument. We found a positive spillover of innovation on firm value added. The results also show that process innovation spillovers are more prevalent than product innovation spillovers.  相似文献

This article studies the long-run impact of HIV/AIDS on per capita income and education. We focus on the disincentive to human capital accumulation given by shorter life span. We work with a continuous time overlapping generations model with education and saving decisions, calibrated for a cross-section of countries. The simulations predict that the most affected countries in Sub-Saharan Africa will be in future, on average, 20% poorer than they would be without AIDS. Schooling will decline in some cases such as Botswana, South Africa and Zambia by more than 40%. The impact of population decline was found to be irrelevant.  相似文献

This article aims to understand the determinants influencing the number of association meetings held in countries worldwide and which may be controlled by their economic agents and policymakers. For this purpose, we use a dynamic panel model with data provided by the Data World Bank, the World Travel & Tourism Council, and the International Congress and Convention Association, in a time series of 8 years. The results reveal the importance of the experiences obtained by the tourists in previous meetings, as well as the countries’ need to implement measures to stimulate the dynamism of economic activity and political stability.  相似文献
