This paper characterizes the frequency domain properties of feedback control rules in linear systems in order to better understand how different policies affect outcomes frequency by frequency. We are especially concerned in understanding how reductions of variance at some frequencies induce increases in variance at others. Tradeoffs of this type are known in the control literature as design limits. Design limits are important in understanding the full range of effects of macroeconomic stabilization policies. We extend existing results to account for discrete time bivariate systems with rational expectations. Application is made to the evaluation of monetary policy rules.  相似文献

This paper deals with the analysis of seasonally, fractionally integrated, multivariate models. We present a procedure that permits us to test the seasonal fractional differencing parameters from the reduced-form system, which allows us to recover the parameters of the structural model through simple restrictions as in the standard VAR case with the additional incorporation of seasonality and fractional integration. An empirical application based on a bivariate system using GDP and unemployment in the UK, USA and Japan is also carried out at the end of the paper.  相似文献

We present evidence on whether and how a household's behavior is influenced by the presence and characteristics of its extended family. Using data from the PROGRESA program in Mexico, we exploit information on the paternal and maternal surnames of heads and spouses in conjunction with the Spanish naming convention to identify the inter- and intra-generational family links of each household to others in the same village. We then exploit the randomized research design of the PROGRESA evaluation data to identify whether the treatment effects of PROGRESA transfers on secondary school enrolment vary according to the characteristics of extended family. We find PROGRESA only raises secondary enrolment among households that are embedded in a family network. Eligible but isolated households do not respond. The mechanism through which the extended family influences household schooling choices is the redistribution of resources within the family network from eligibles that receive de facto unconditional cash transfers from PROGRESA, towards eligibles on the margin of enrolling children into secondary school.  相似文献

This paper investigates the potential of models of the range of equilibria to yield a pattern of equilibrium rates of unemployment that is consistent with the observed mix of cycle with no trend in the rate of unemployment. To do this the paper considers a model in which wages are determined by a group of unionised insiders bargaining with an employer. In the model the supply of labour is endogenous. Specifications of the utility function are found which are consistent with the mix of cycle and no trend in the rate of unemployment. Of these it is concluded that loss aversion in the evaluation of wage relativities is a crucial ingredient for models of the range of equilibria.  相似文献

We study the determinants of country default risk by applying a Multiple Indicators Multiple Causes (MIMIC) model. This accounts for the fact that country default risk is an unobservable variable. Whereas existing (regression-based) approaches typically use only one of several possible country default risk indicators as the dependent variable, the MIMIC model enables us to consider several indicators at once. The simultaneous consideration of sovereign yield spreads and Standard and Poor (S&P) ratings may help to improve the identification of the latent country default risk. Our results confirm most of the literature's main findings regarding important determinants of country default risk, refute others and provide new evidence to controversial questions.  相似文献

Mainstream economists and liberal politicians are criticizing the Third Way as it is being applied in the Netherlands. They argue that mutual consultation precludes an efficient adaptation to disturbances. The present study analyzes changes in wage and income policy in the Netherlands until 2005. It finds that wage and income policy has proven to be flexible enough to address “new” challenges in the Netherlands. The flexibility is rooted in a culture of tolerance that allows for some breaking of working rules. The latter arises from bounded socialization, that is, the imperfect transmission of information with respect to social working rules that result in similar but not identical copies of institutions.  相似文献

This paper uses primary data to analyze the institutions and informal markets that govern groundwater allocation in a sugarcane-cultivating village in North India. We find that, in contrast to earlier literature, the observed water trades result in efficient water allocation across farms. We interpret this and other stylized facts in terms of a social contract using a simple bargaining model with limited inter-player transfers. Poor functioning of the power sector leads to reduced pumping and a water supply constraint. Simulations show that power supply reform can significantly increase farm yields, and be financed out of increased farm profits.  相似文献

While John R. Commons often referred to third sector organizations, such as associations, cooperatives, and trade unions, it is unclear how these organizations can be fitted into his transactional typology. This paper clarifies this problem by identifying two dimensions of bargaining, managerial, and rationing transactions: 1) the extent of legal equality of transactional participants, and 2) the extent of commonness of these participants' transactional interests. These dimensions enable defining the identity of the third sector in terms of a distinct variety of rationing transactions combining legal equality of transactional participants with significant commonness of their interests. The paper further explores several implications of this argument for new institutional economics, concerning the citizenship aspect of markets and hierarchies and the possibility of viewing third sector organizations as hybrids between markets and hierarchies. The paper concludes with a discussion of the implications for further research.  相似文献

Abstract.  We study a model designed to understand the concept of unbalanced growth. We define leading sectors to be those that raise the profits from industrialization for other sectors the most. We identify the leading sectors and show that subsidizing them in sequence will raise welfare if the future is not discounted too strongly.  相似文献
