In this note, we revisit minimum quality standards (MQS) under a vertically differentiated duopoly. We generalize the model in Ronnen (1991) and Valletti (2000) by introducing asymmetry into the fixed cost of quality improvement and by explicitly taking into account the endogeneity of quality ordering. In the generalized model, we show that the results derived by Ronnen (1991) and Valletti (2000) are largely robust. 相似文献

We consider the estimation of the coefficients of a linear structural equation in a simultaneous equation system when there are many instrumental variables. We derive some asymptotic properties of the limited information maximum likelihood (LIML) estimator when the number of instruments is large; some of these results are new as well as old, and we relate them to results in some recent studies. We have found that the variance of the limiting distribution of the LIML estimator and its modifications often attain the asymptotic lower bound when the number of instruments is large and the disturbance terms are not necessarily normally distributed, that is, for the micro-econometric models of some cases recently called many instruments and many weak instruments. 相似文献

The Asymptotic Expansion Approach to the Valuation of Interest Rate Contingent Claims 总被引:2,自引:0,他引:2
We propose a new methodology for the valuation problem of financial contingent claims when the underlying asset prices follow a general class of continuous Itô processes. Our method can be applied to a wide range of valuation problems including complicated contingent claims associated with the term structure of interest rates. We illustrate our method by giving two examples: the valuation problems of swaptions and average (Asian) options for interest rates. Our method gives some explicit formulas for solutions, which are sufficiently numerically accurate for practical purposes in most cases. The continuous stochastic processes for spot interest rates and forward interest rates are not necessarily Markovian nor diffusion processes in the usual sense; nevertheless our approach can be rigorously justified by the Malliavin–Watanabe Calculus in stochastic analysis. 相似文献

We examine how the development of the agro-processing industry contributed to poverty reduction in Thailand. The effects on farmers’ income are emphasized because most of the poor in Thailand are farmers. The development of the agro-processing industry could improve farmers’ income through two channels: (i) the purchase of agricultural products; and (ii) the employment of the poor farmers at factories. We show that the development of the agro-processing industry, which also played a leading role in the high economic growth of the Thai economy, contributed to poverty reduction through both of the two channels. It was hence pro-poor. 相似文献

This paper examines the impact of prime‐age adult mortality on the transition made by adolescents from school to the labour market and on female adult labour force participation decisions in South Africa. We find, first, that deaths of prime‐age adults significantly increase both male and female adolescents’ labour force participation as they stop their schooling. Secondly, the death of prime‐age adults in general also decreases school enrolment ex ante. Thirdly, female adults tend to join the labour force following the death of prime‐age adult males. These findings imply that prime‐age adult mortality increases labour supply and disrupts human capital formation. 相似文献

This study examines how organizing is done reflexively through practice in the context of knowledge sharing. Organizing concerns reduction of equivocality and sensemaking so that actions can be interpreted and coordinated. Reflexivity refers to the fact that this organizing is done through talk, and that talk is an action that requires organizing. To examine how this reflexive organizing is accomplished, detailed analysis of video‐recorded interactions among photocopier service technicians revealed various interactional methods to make actions of requesting and offering assistance understandable and relevant. To explain these methods, Goffman's concept of embedding is applied. By embedding other social situations in the current talk, one can project a certain sense of one's talk. This reflexive organizing clarifies that organizing is part of, not separate from, any practice and that knowledge sharing is accomplished not through a retrospective narrative but through reflexive construction of the situation in which talk is made possible. 相似文献

For estimating the integrated volatility and covariance by using high frequency data, Kunitomo and Sato (Math Comput Simul 81:1272–1289, 2011; N Am J Econ Finance 26:289–309, 2013) have proposed the separating information maximum likelihood (SIML) method when there are micro-market noises. The SIML estimator has reasonable finite sample properties and asymptotic properties when the sample size is large when the hidden efficient price process follows a Brownian semi-martingale. We shall show that the SIML estimation is useful for estimating the integrated covariance and hedging coefficient when we have round-off errors, micro-market price adjustments and noises, and when the high-frequency data are randomly sampled. The SIML estimation is consistent, asymptotically normal in the stable convergence sense under a set of reasonable assumptions and it has reasonable finite sample properties with these effects. 相似文献

This paper examines strategic investment subsidies in an international oligopoly. A general oligopoly model is constructed in which firms compete in two stages and governments commit to investment subsidies prior to firms' actions. The paper considers asymmetry among firms that arises from the nature of goods they produce rather than their cost structures. When firms produce asymmetrically differentiated goods, it is found that a change in the number of foreign competitors may alter the sign of the optimal unilateral investment subsidy. An example of policy reversal is provided in the case of strategic research and development subsidies for a quality‐differentiated industry. 相似文献

This paper shows that some of the main policy implications in Park (2001 ) and Zhou, Spencer, and Vertinsky (2002 ) are sensitive to their assumptions on marginal production costs. The unilaterally optimal policy for investment towards quality improvement is analyzed, assuming constant and non‐negative marginal production costs under vertically differentiated international duopoly. If marginal production costs are different across firms, the optimal policy for each exporting country may be opposite in its sign from that shown by the existing papers under Bertrand competition. The policy reversal may also occur for the low‐quality exporting country under Cournot competition. 相似文献

We examine the optimal rules of origin (ROO) in a free trade area/agreement (FTA) by employing a stylized three-country partial equilibrium model of an international duopoly. We incorporate compliance costs of the ROO into the model. In particular, compliance costs are higher for a firm located in a non-member country of the FTA than for a firm (an internal firm) located in an FTA member country, whereas marginal production costs are lower for the former. The FTA member countries set the optimal level of ROO to maximize their joint welfare. An importing country within the FTA imposes tariffs on imports that do not comply with the ROO. We show that the optimal ROO may have a protectionist bias in the sense that they are set for only the internal firm to comply. ROO may also cause low utilization of FTAs when they are set such that even the internal firm does not comply with them. These cases arise depending on parameter values. 相似文献
