This paper provides a framework with which to analyze organizational forms in the knowledge economy. We focus on an important trade-off facing modern firms: firms can acquire the property of all the innovations developed by their employees and can greatly increase their profits, yet this type of private intellectual property rights regime can discourage the innovative effort of the very same workers. Allowing workers to carry their knowledge outside the firm eliminates this disincentive. Hence, strategic complementarities may exist between innovative partners and a disclosure driven intellectual property rights regime, and passive employees and a private intellectual property rights regime. An evolutionary game theoretic model demonstrates these strategic complementarities and shows when economies tend towards disclosure driven or private intellectual property rights regimes.  相似文献

It is well‐known that product differentiation eliminates the Bertrand paradox (i.e. marginal cost pricing under duopoly). While differentiation is often justified with reference to the consumer's ‘preference for variety’, the conditions under which such a preference is likely to arise are rarely considered. We investigate this question in a setting in which uncertainty about product quality can endogenously generate either convex or non‐convex preferences. We show that even when two goods are ex ante homogeneous, quality uncertainty can eliminate the Bertrand paradox.  相似文献

A Welfare-to-Work (WTW) program is a mix of government expenditures on various labour market policies targeted to the unemployed ( e.g. unemployment insurance (UI), job search monitoring (JM), social assistance (SA), wage subsidies). This paper provides a dynamic principal–agent framework suitable for analysing chief features of an optimal WTW program, such as the sequence and duration of the different policies, the dynamic pattern of payments along the unemployment spell, and the emergence of taxes/subsidies upon re-employment. The optimal program endogenously generates an absorbing policy of last resort ("social assistance") characterized by a constant lifetime payment and no active participation by the agent. Human capital depreciation is a necessary condition for policy transitions to be part of an optimal WTW program. The typical sequence of policies is quite simple: the program starts with standard UI, then switches into monitored search and, finally, into SA. The optimal benefits are decreasing during unemployment insurance and constant during both JM and SA. Whereas taxes (subsidies) can be either increasing or decreasing with duration during UI, they must decrease (increase) during a phase of JM. In a calibration exercise, we use our model to analyse quantitatively the features of the optimal program for the U.S. economy. With respect to the existing U.S. system, the optimal WTW scheme delivers sizeable welfare gains to unskilled workers because the incentives to search for a job can be retained even while delivering more insurance and using costly monitoring less intensively.  相似文献

We investigate issuers withdrawing an IPO (after security regulation filings) that return later for a successful offering. Venture capital backing and reputation of the lead underwriter are key factors in predicting successful return. The possibility of returning has a significant impact on the decision to withdraw and the pricing of offerings that succeed. Our sample of returning IPOs also provides a unique setting to investigate underwriter switching after a withdrawal but before a successful IPO. We find that switching occurs in response to poor bank performance and when switching firms “graduate” to banks that have high industry market shares.  相似文献

South Korean Labor Market Discrimination Against Women: Estimating Its Cost   总被引:1,自引:0,他引:1  
A bstract . South Korean chaebols (large family owned firms) have extensive government ties which provide them with favorable treatment. In turn, the government obtains support from the chaebols. The chaebols have gained economic or excess profits through exploiting monopolistic power in the domestic South Korean product market and through exploiting monopsonistic power in the domestic factor market.
How a monopsonistic firm obtains excess profits is illustrated and related to the behavior of the chaebols as a whole. Major focus is on the labor market. The chaebols have discretionary power over how to exploit their monopsonistic position. The status of women in the South Korean work force in light of this discretionary power is considered. An estimate of the income loss involved is made.  相似文献

This paper proposes a technique for computing optimal taxes in a full general equilibrium model. It is based upon a fixed point algorithm of the type that is widely used to solve Walrasian general equilibrium models. Computing an optimal tax equilibrium is more difficult than solving a general equilibrium model only to the extent that the derivatives of the social welfare function and of the consumer demand functions must be calculated in the former case. Solutions to several sample problems are provided to demonstrate the technique. They suggest that optimal tax rates are exceedingly sensitive to the specification of the model used to derive them.  相似文献

Using unique data from Hungary, the gap in reading and mathematics test scores between Roma and non‐Roma 8th grade students is assessed and a substantial gap between them revealed. Standardized test scores as well as the fraction of students with competences considered inadequate are examined. Regardless of measurement and subject area, the bulk of the gap is explained by social differences in income, wealth and parental education. Using reduced‐form regressions, two major mediating mechanisms are identified: first, on average the home environment of Roma children is less favourable for cognitive development; second, the educational environment of the average Roma student is different from the average non‐Roma student. Comparing students with similar home environments from the same school and class, the ethnic gap in test scores is found to be insignificant. Ethnic differences in the home environment are explained by social disparity, and ethnicity seems to play no additional role in that regard. The unequal distribution of Roma students in schools and classes is found to be explained predominantly by social difference, too, with a significant residual portion, indicating the effect of ethnic segregation.  相似文献
