We study the cyclical effects of the timing of durable goods purchases in a general equilibrium model in which both durable and non-durable goods are consumed and the durable good is lumpy. At the microeconomic level, the timing of durable goods purchases supplies some insulation for non-durable consumption over the cycle. At the macroeconomic level, the timing decisions tend to amplify and propagate wealth and income shocks. Our model also allows for endogenous price determination. When the price of the durable changes due to inflexibility of workers between sectors, the effect of adverse shocks is even stronger and longer. 相似文献
Governments and central banks need to have an accurate and timely assessment of indicators for the current month, as this is essential for providing a reliable and early analysis of the current economic situation. The index of industrial production (IIP) is probably the most important and widely analyzed monthly indicator, given the relevance of the manufacturing activity as a driver of the whole business cycle. This paper presents a series of models conceived to forecast the current French monthly IIP, based on regression models and dynamic factor models. The combination of these two approaches allows selecting economically relevant explanatory variables among a large data set. In addition, a rolling forecast study is carried out to assess the forecasting performance of the estimated models, using predictive ability and model confidence set tests. This latter allows getting several models displaying equivalent forecasting performance and therefore gives robustness to the forecasting exercise rather than to base the forecasting analysis only on one model. 相似文献
We consider environments in which agents other than innovator receive the signals about the quality of innovation. We study whether mechanisms can be found which exploit market information to provide appropriate incentives for innovation. If such mechanisms are used, the innovator has incentives to manipulate market signals. We show that if an innovator cannot manipulate market signals, then the efficient levels of innovation can be uniquely implemented without deadweight losses – for example, by using prizes. Patents are necessary if the innovator can manipulate market signals. For an intermediate case of costly signal manipulation, both patents and prizes may be optimal. 相似文献
Peru is the second-largest producer and exporter of copper in the world. This paper proposes a novel approach to assess short-run and long-run effects of copper on Peru’s recent economic growth. Annual data over the 2014–2018 period were used to calculate a Mining Contribution Index (MCI). An institutional quality indicator of the World Competitiveness Index of the World Economic Forum measured the dependence of Peruvian economic growth on mining and the quality of its institutions, respectively. Then, monthly data during the period 2005–2018 were used to run vector autoregressive (VAR) and vector error correction (VEC) models to measure copper’s effects on the country’s economy over time. VAR-VEC models included copper production, exports, international price, investment, taxes paid by producing companies, and Peru’s gross domestic product (GDP). Stationarity and causality of variables were verified with the Augmented Dickey-Fuller and Granger tests, respectively. Due to the presence of non-stationary variables, a VEC model was implemented to forecast short- and long-run effects. The main results show that real GDP responds to copper output and other related explanatory variables differently, depending upon the instrument applied. Peruvian GDP has increased dependence on copper mining. The quality of its institutions could explain the presence of Dutch Disease or resource curse theory. Short- and long-run effects of copper output on GDP were generally statistically non-significant. GDP was statistically significant in relation to other mining variables, such as copper exports and the international price of copper.
The challenges posed by the economic downturn on baccalaureate nursing schools in the southeast as it relates to their perceptions of changes in the number of applicants, acceptance rates, employer recruitment efforts, and student clinical and job placement were explored. Responses from deans and program directors indicated nursing schools are experiencing negative effects of the economic downturn in the form of graduates having difficulty finding employment, decreased recruitment efforts from prospective employers, difficulty locating clinical placements for students, and no change in faculty applicants despite an increase in undergraduate student applicants as well as graduate student applicants. These multiple factors combined could signal the death knell for programs that are ill-prepared to deal with such a crisis. Programs need to be aggressive in their efforts to draw health care recruiters as well as qualified faculty applicants to their campuses. Nursing schools must be able to clearly show why their graduates are superior to other programs' graduates when competing for both highly qualified faculty applicants and prospective student employers. 相似文献
Governments around the world are beginning to embrace a new form of environmental regulation – mandatory disclosure of information.
While information disclosure programs appear to have an impact on subsequent firm behavior – often resulting in lower levels
of pollution – little is known about the costs and benefits of these programs and whether or not they enhance social welfare.
This paper presents a simple bargaining model where mandatory information disclosure is used to overcome a lack of information
on the part of the public. We characterize the conditions under which information disclosure will lead to a reduction in emissions,
and ultimately, the conditions under which it will enhance social welfare. Several extensions of the model are briefly explored,
including the effect of two sources of pollution – only one of which is subject to information disclosure.

Extensive research has been devoted to the quality of analysts' earnings forecasts. The common finding is that analysts' forecasts are not very accurate. Prior studies have tended to focus on the mean of forecasts and measure accuracy using various summaries of forecast errors. The present study sheds new light on the accuracy of analysts' forecasts, by measuring how well calibrated these forecasts are. The authors follow the tradition of calibration studies in psychological literature and measure the degree of calibration by the hit rate. They analyze a year's worth of data from the Institutional Brokers Estimate System database, which includes over 200,000 annual earnings forecasts made by over 6,000 analysts for over 5,000 companies. By using different ways to convert analysts' point estimates of earnings into a range of values, the authors establish the bounds that are necessary to determine the hit rates, and examine to what extent the actual earnings announced by the companies are bracketed by these intervals. These hit rates provide a more complete picture of the accuracy of the forecasts. 相似文献
The cost and time required to produce original benefit estimates makes benefit transfers a highly valuable component of the process of assessing the benefits and costs of environmental improvements. Because of the great variety of benefit estimates, conducted at different times with different data sources and different techniques, there is concerted effort to understand the validity of transfers. The research in this paper approaches the validity issue of benefit transfers by asking whether there is indirect evidence of the benefits. The premise of the paper is that policies that give significant benefits should induce expected and unexpected behavioral changes. We look for evidence of potential indirect evidence by by estimating the effect of differences air pollutants on activities such as outdoor recreation and work, as found in the American Time Use Survey. 相似文献
We analyze normal form games where a player has to pay a price to a supplier in order to play a specific action. Our focus is on supplier competition, arising from the fact that distinct suppliers supply different players, and possibly different actions of the same player. With private contracts, where a player only observes the prices quoted by his own suppliers, the set of equilibrium distributions over player actions coincides with the set of equilibrium distributions when all actions are supplied competitively, at cost. With public contracts, the two distributions differ dramatically even in simple games. 相似文献
