A bstract . Various European measures to alleviate hardships following structural changes. including those resulting from changes in international trade. particularly imports. are summarized. It is noted that sectional political pressures tend to generate industry-specific schemes, especially in the textile, clothing and footwear fields. In some cases, the individual schemes facilitate change. But, in many others, they simply frustrate and hinder inevitable adjustment. Instances of both types are cited. The characteristics of an 'ideal' scheme are itemized along with some of the difficulties in maintaining them. Finally, suggestions are made to de-politicize the tariff-maknig process in the interest of freer trade. 相似文献

There is much evidence against the so-called “too big to fail” hypothesis in the case of bailouts to subnational governments. We look at a model where districts of different size provide local public goods with positive spillovers. Matching grants of a central government can induce socially-efficient provision, but districts can still exploit the intervening central government by inducing direct financing. We show that the ability and willingness of a district to induce a bailout and district size are negatively correlated. Furthermore, we argue that these policies can be equilibrium strategies. 相似文献

The aim of this paper is to introduce the notion of symmetry in a Lévy market. This notion appears as a particular case of a general known relation between prices of put and call options, of both the European and the American type, which is also reviewed in the paper, and that we call put–call duality. Symmetric Lévy markets have the distinctive feature of producing symmetric smile curves, in the log of strike/futures prices. Put–call duality is obtained as a consequence of a change of the risk neutral probability measure through Girsanov's theorem, when considering the discounted and reinvested stock price as the numeraire. Symmetry is defined when a certain law before and after the change of measure through Girsanov's theorem coincides. A parameter characterizing the departure from symmetry is introduced, and a necessary and sufficient condition for symmetry to hold is obtained, in terms of the jump measure of the Lévy process, answering a question raised by Carr and Chesney (American put call symmetry, preprint, 1996). Some empirical evidence is shown, supporting that, in general, markets are not symmetric. 相似文献

Attitudes towards risk are measured for households in Northern Zambia using an experimental gambling approach with real payoffs that at maximum were equal to 30% of average total annual income per capita. The results of the experiment show decreasing absolute risk aversion and increasing partial risk aversion. Determinants of risk aversion are investigated using random effects interval regression model exploiting the panel data structure of the repeated experiments. Wealth indicator variables are found to be significant, and partial relative risk aversion decreases as wealth increases. Females are found to be more risk averse than males. 相似文献

This article examines factors related to a livestock rental market in western Nepal and assesses whether this market is associated with caste differentiation and land rental market participation. Theoretical models for asset‐rich (i.e., high‐caste) households, rich in land and livestock, and asset‐poor (i.e., low‐caste families) households are presented to provide logical explanations for the existence of a livestock rental market and the synergy between livestock and land rental markets participation. A combination of double hurdle models and bivariate‐ordered probit models were used to test the implications of the models. Consistent with the theoretical models, land‐ and livestock‐rich high‐caste households were more likely to rent out land and/or livestock, whereas land‐ and livestock‐poor and credit constrained low‐caste households were more likely to rent livestock and land from others. Participation in the two markets was positively correlated, indicating a synergistic relationship that may be due to production and transaction costs reducing benefits. Policies that can enhance the allocative efficiency of livestock and land rental markets can improve equity as well as efficiency of land use in Nepal. Provision of livestock credit to land‐poor low‐caste households is also crucially dependent on their access to more long‐term contracts for land. 相似文献

A two-species bioeconomic model is analyzed, but in contrast to most similar models, there is no biological interaction between the species, only economic. The interaction takes place in the market where the quantity of either species may affect the price of the other. The effects of cross-price elasticities on the optimal steady state and on the optimal paths in the sole-owner case are investigated both analytically (steady states) and numerically (optimal paths). First, it is shown that if the harvest of one species has impact on the price of another species, then this has a positive effect on its steady-state stock. The effect increases with the stock-elasticity in the cost function. Further, in the case of linear demand functions, the steady state outcome depends solely on the sum of the cross-price parameters and not their individual values. Secondly, in the investigation of optimal paths, it is shown that if the harvest of one species has impact on the price of the other, optimal trajectories reach steady state faster for itself and slower for the other species. Further, when cross-price elasticities are sufficiently high, the paths go from being monotonic to feature over- or undershooting. 相似文献

The extremely challenging external environment poses numerous challenges to union formation among call centre agents in India. Complicating matters is the acquired professional identity of call centre agents. In this scenario, the union organising call centre employees envisaged that partnership with employers was the only possibility acceptable to call centre agents, employer organisations and society at large, enabling them to regain some acceptability and credibility for the heretofore tainted Indian trade union movement. 相似文献
