Individual labor earnings observed in worker panel data have complex, highly persistent dynamics. We investigate the capacity of a structural job search model with on‐the‐job search, wage renegotiation by mutual consent, and i.i.d. productivity shocks to replicate salient properties of these dynamics, such as the covariance structure of earnings, the evolution of individual earnings mean, and variance with the duration of uninterrupted employment, or the distribution of year‐to‐year earnings changes. Structural estimation of our model on a 12‐year panel of highly educated British workers shows that our simple framework produces a dynamic earnings structure that is remarkably consistent with the data. 相似文献

Perspectives on the Sources of Heterogeneity in Indian Industry 总被引:3,自引:0,他引:3

This paper examines technical efficiency variation across four industrial sectors in India using a stochastic production frontier technique. The results obtained are comparable to technical efficiency distribution patterns obtained in other countries. Heterogeneity in firm-level efficiency is examined against internal, firm-level and external, industry and location characteristics. The results suggest that managerial effectiveness significantly influences efficiency and that there are considerable benefits deriving from location within established industrial clusters for particular industries. The methodology and findings indicate that the study of industry-specific technical efficiency patterns is a useful analytic tool for tracking firm response to ongoing liberalization. 相似文献

This paper empirically assesses co-movements in emerging market bond returns and disentangles the roles of external and domestic factors during episodes of heightened market volatility. The conceptual framework, set in the context of asset allocation, allows us to describe the channels through which shocks originating in a particular emerging or mature market are transmitted across countries and markets. We show that a simple measure of cross-country correlations, when presented together with the more commonly used average correlation coefficient, can be more informative during episodes of heightened market volatility. Data for the period 1997–2008 are analysed for evidence of true contagion and common external shocks. 相似文献

Current interest in the new economic growth theory, linked with the development of new, innovative methods of measurement,
has resurrected interest in spatial economic convergence. The primary objective of this paper is to examine the extent that
regional economies seem to be converging or diverging. It explores the expanding theoretical literature in the field and examines
the growing body of empirical evidence that has emerged in recent years not only in the U.S. but also internationally. The
paper is retrospective but also embraces new findings relating to the United Kingdom and the U.S., putting particular emphasis
on long- and short-term indicators of economic convergence. 相似文献

The more industrialized LDCs are emerging increasingly as exporters of capital (or of technology in several forms). This paper draws on the recent experience of Indian MNCs to reexamine the factors which give rise to Third World multinationals. The author summarizes the current state of research in the analysis of LDCs MNCs, drawing upon specific MNC literature and other related literature on trade and technology. He deals with the evidence on Indian capital exports, placing it in the broader context of technology exports, discussing some examples of interest and drawing comparisons with foreign investment by some other LDCs. He assesses the Indian experience, using the distinctions drawn by Dunning's ‘eclectic’ theory but concentrating on the processes of technical change that underline the growth of its MNCs. The final section draws some tentative conclusions. 相似文献

This paper examines how strategic managerial delegation affects firms' timing of adoption of a new technology under different modes of product market competition. It demonstrates that strategic delegation has differential impacts on adoption dates under Cournot and Bertrand competitions. Strategic delegation with ‘own-performance’-based incentive schemes always leads to early adoption in markets with Bertrand competition compared to that under no-delegation, but not necessarily so in markets with Cournot competition. It also shows that under strategic delegation with ‘own-performance’-based incentive schemes, adoption occurs earlier (later) in markets with Cournot competition than in markets with Bertrand competition, if the degree of product differentiation is high (low). In contrast, under strategic delegation with ‘relative-performance’-based incentive schemes, adoption dates do not differ across markets with different modes of competition. It also analyses implications of firms' choice over types of managerial incentive schemes on the speed of diffusion of new technology. 相似文献

This study examines the impact of stock split and stock dividend announcements made by closed end mutual funds. We argue that the asymmetric information / signaling hypothesis does not apply to mutual funds. Therefore, any announcement effects must be attributed to other factors such as the optimal trading range hypothesis. We find that closed end funds react no differently than other firms to stock distribution announcements; also, trading volume and turnover remain unchanged after closed end funds' ex-stock distribution days, while liquidity declines for other firms that distribute shares. 相似文献

Land-use changes, forest/soil conditions and carbon sequestration dynamics: A bio-economic model at watershed level in Nepal 总被引:1,自引:0,他引:1

A dynamic bio-economic model has been used at watershed level in Nepal to analyze the land-use changes, forest and soil conditions and their resultant impacts on carbon (C) sequestration. Planning horizon of the model extends over a period of 25 years. The objective function is maximization of the sum of discounted net income flows from agriculture, livestock and forestry productions; imputed value of leisure and labour hiring out activities subject to annual constraints on land, labour and capital availability along with the fulfilment of minimum cash and consumption requirements. The seven scenarios analyzed by the model are: business as usual (BAU), reduction in population growth rate from 2 to 1.5% p.a., increased prices of major crops by 10 and 20%, reduction in emigration of active labour force from the watershed from the current rate of 20–15 and 10%, and increase in discount rate from 5 to 10%. The results indicate that reduced labour emigration rates and increase in the prices of major crops lead to expansion of cultivated area and shift from one land use to the others. Land clearing becomes more severe with decline in labour emigration rate. Up to 10% increase in the prices of agricultural crops does not have noticeable effect on total land clearing. Increase in discount rate leads to less land clearing, more biomass harvesting and higher net C sequestration as compared to the BAU scenario. Assuming a C price of 10 USD per MgC and 5% discount rate, the net present value of C sequestration for the first 25 years is estimated at 1.83 mill USD in the BAU scenario, varying from 0.16 mill USD to 2.26 mill USD, as respectively the lowest and highest values for the seven scenarios analysed. A reduction in population growth and maintenance of current rate of off-farm employment are suggested for slowing down the expansion of cultivated land area, and thereby reducing the forest/soil degradation and C emissions. This in turn would enhance the income potential from C sequestration. 相似文献
