Welfare reducing licensing 总被引:2,自引:0,他引:2
In this paper, we characterize situations where licensing a cost reducing innovation to a rival firm using two-part tariff contracts (a fixed fee plus a linear per unit of output royalty) reduces social welfare. We show that it occurs if (i) the firms compete in prices, (ii) the innovation is large enough but not drastic, and (iii) the goods are close enough substitutes. Moreover, we show that, regardless of the type of competition, first, the optimal contract always includes a positive royalty and, second, even drastic innovations are licensed whenever the goods are not homogeneous. 相似文献

We build on our earlier model of money in which bank liabilities circulate as a medium of exchange. We investigate optimal bank behavior and the resulting provision of liquidity under a range of central bank regulations. In our model, banks issue inside money under fractional reserves, facing the possibility of excess redemptions. Banks consider the float resulting from money creation and make reserve‐management decisions that affect aggregate liquidity conditions. Numerical examples demonstrate positive bank failure rates when returns to banking are low. Central bank interventions may improve banks' returns and welfare through a reduction in bank failure. 相似文献

AbstractThis paper contributes to the empirical research around the “wage-led” or “profit-led” demand regimes. It first reviews how Kalecki, and then Steindl, approached the relationship between economic growth and income distribution. Then, empirical analysis carried out under the probabilistic approach to econometric modeling shows statistical evidence, estimated through cointegration analysis, that in the long run, in three very open economies—Mexico, France, and Korea—the wage share is positively associated with demand and output. It finally discusses the macroeconomic dilemma that almost all countries have to face, i.e., a positive effect of a high-wage policy on demand and employment may diverge from a negative effect on output compatible with external equilibrium. 相似文献

This paper develops a contractarian theory of the state and the existence of redistribution. The existence of rules of redistribution is explained without any recourse to the risk-aversion of agents. No veil of ignorance is needed. This avoids obligational problems inherent in most other contractarian theories of justice. Hence, this paper departs from the standard legitimization of redistribution as fundamental insurance and interprets it as stemming from a principle of reciprocity in trade. Since this paper deals with an anarchic society, the implementation of redistributional rules is constrained by the assumption of self-enforcement. We show that this assumption changes the interpretation of the state: the state is characterized by a particular design of equilibrium strategies, not by the existence of enforcement agencies. 相似文献

The present paper considers some new models for the analysis of multidimensional contigency tables. Although the theoretical background used here appeared already in Haberman (1974), prescribed conditional interaction (PCIN) models were introduced by Rudas (1987) and their mathematical properties were worked out by Leimer and Rudas (1988). These models are defined by prescribing the values of certain conditional interactions in the contingency table. Conditional interaction is defined here as the logarithm of an appropriately defined conditional odds ratio. This conditional odds ratio is a conditional version of a generalization of the well known odds ratio of a 2×2 table and that of the three factor interaction term of a 2×2×2 table and applies to any number of dimensions and any number of categories of the variables. The well known log-linear (LL) models are special PCIN models. Estimated frequencies under PCIN models and tests of fit can be computed using existing statistical software (e.g. BMDP). The paper describes the class of PCIN models and compares it to the class of association models of Goodman (1981). As LL models are widely used in the analysis of social mobility tables, application of more general PCIN models is illustrated. 相似文献

Certain manuals and computer programs mistakenly identify the mean with the constant in Box-Jenkins time series models. In this paper, it will be shown that (a) the mean and the constant have different values in autoregressive models, and (b) they have an algebraic and graphical relationship. 相似文献

We examine the incentives for upstream firms to consolidate horizontally and the impact of this process on industry performance, when there are downstream entry barriers and firms negotiate bilaterally. In the short run, consumers are not worse off with upstream mergers, since consolidation only results in a redistribution of industry rents. In the long run, consumers are better off after upstream mergers, since they induce more entry into that segment. When social welfare is evaluated, a limit on upstream consolidation may prevent excessive entry; but upstream entry can be sometimes insufficient, if the retailers' intrinsic bargaining power is excessive. 相似文献

Although credit risk is an important factor that financial institutions must cope with, the determinants of bank problem loans have been little studied. Using panel data, we compare the determinants of problem loans of Spanish commercial and savings banks in the period 1985–1997, taking into account both macroeconomic and individual bank level variables. The GDP growth rate, firms, and family indebtedness, rapid past credit or branch expansion, inefficiency, portfolio composition, size, net interest margin, capital ratio, and market power are variables that explain credit risk. However, there are significant differences between commercial and savings banks, which confirm the relevance of the institutional form in the management of credit risk. Our findings raise important bank supervisory policy issues: the use of bank level variables as early warning indicators, the advantages of bank mergers from different regions, and the role of banking competition and ownership in determining credit risk. 相似文献

The objective of this paper is to evaluate the impact on bank credit exposures to small- and medium-sized Spanish firms of the current proposal for reform of the 1988 Capital Accord using information from the Spanish Credit Register. Capital requirements for exposures to those firms, according to the various revisions of the proposed capital reform (from the January 2001 consultative document to the April 2003 one), are calculated to analyze whether the existing pattern of bank financing of small- and medium-sized firms might be altered. Finally, the incentives for individual banks to adopt the advanced internal ratings-based approach proposed by Basel II are evaluated. 相似文献

Investment costs for fish processing plants are hereby presented along with a detailed analysis of different types of processes in relation to economies of scale.The cost-capacity factor for fish industry is estimated as 0.84, except for fish meal plants where the cost-capacity factor is 0.61.It is also discussed how technology, capacity and location in developed and developing countries can affect investment costs for fish processing plants, while cost-capacity factors remain unchanged.The concept of minimum limit for industrial capacity is included. Investment costs for minimum size plants or plants below minimum size are even greater than what would correspond to the correlation line. This is due to the need to incorporate one or more oversized pieces of equipment. 相似文献
