The aim of this paper is to assess whether modeling structural change can help improving the accuracy of macroeconomic forecasts. We conduct a simulated real‐time out‐of‐sample exercise using a time‐varying coefficients vector autoregression (VAR) with stochastic volatility to predict the inflation rate, unemployment rate and interest rate in the USA. The model generates accurate predictions for the three variables. In particular, the forecasts of inflation are much more accurate than those obtained with any other competing model, including fixed coefficients VARs, time‐varying autoregressions and the naïve random walk model. The results hold true also after the mid 1980s, a period in which forecasting inflation was particularly hard. Copyright © 2011 John Wiley & Sons, Ltd. 相似文献

I study the interaction between discrimination and investment using a directed search model where firms decide the capital intensity of their production technologies before being matched. Discrimination makes some workers cheap to hire. As a consequence, some firms might save on capital costs adopting labour intensive technologies. This framework allows one to reconcile search models with three well-known facts regarding the labour market outcomes of minority workers: low wages, high unemployment and occupational segregation. Furthermore, the model questions the role of equal pay legislation in reducing inequality since removing this restriction, i.e., allowing firms to post type-contingent wages, eliminates the negative effects of discrimination on investment and wages. 相似文献

Recognizing the inflexibility inherent in standard capital budgeting analysis, recent research has provided new insights using a real options framework. This paper uses the explicit finite difference approach to value real options. However, instead of assuming a constant return and volatility term, we assume that these variables are sensitive to changes in the economic environment. Accordingly, we adapt our approach to incorporate a Markov switching feature. Further, we recognize that some of the modeling assumptions can be violated in a practical application. Therefore, we recommend using range based estimates of the real option value, as opposed to a point estimate. 相似文献

We offer an analysis of the existence of a positive relationship between minimum wages and economic growth in a simple one-sector
overlapping generations economy à la Romer (J Polit Econ 94:1002–1037, 1986), in the case of both homogeneous and heterogeneous labour and without considering any growth-sustaining externalities which
the minimum wage can generate. Assuming also the existence of unemployment benefits financed with balanced-budget consumption
taxes not conditional upon age, we show that the minimum wage can promote economic growth and welfare despite the occurrence
of unemployment. There may also exist a growth- and welfare-maximising minimum wage. 相似文献

This article argues that behaving prosocially reduces regional finance differentials in terms of interest and insolvency rates. This is because prosociality implies more transparent information and cooperation among the parties engaged in a financial contract. The context of study is Italy, well known for its regional economic and financial disparities. The analysis is developed through a cross-regional two period panel model during the years 1998 and 2003. Empirical evidence shows that regions with a higher proportion of prosocial individuals report lower interest and insolvency rates. When legal enforcement is included in the specified model, evidence suggests that more efficient third-party enforcement can transmit a stronger sense of legal abidance and facilitate the internalisation of social norms of cooperation. 相似文献

A monotonic spline parametrization is proposed as a reliable alternative to the traditional Bernstein-based approach for Direct Term Structure Estimation. Numerical experiments with Italian bond data demonstrate the effectiveness of the proposed method. 相似文献

In this paper, we aim at investigating from a game‐theory perspective whether trade liberalization can promote a collusive two‐way trade. We show that, under Cournot competition, economic integration is anti‐competitive if collusive trade is a possible outcome of the repeated game; under price competition, the likelihood of collusive trade is a necessary but not sufficient condition for trade liberalization to be pro‐competitive. Furthermore, we show that economic integration may increase the scope for collusion irrespective of the firms’ strategic variable. 相似文献

This paper compares the degree of openness to trade of three developed countries markets—the European Union, Japan, the United
States—with that of three middle-income countries, namely Brazil, India, and China. A theoretically consistent protection
measure—the Mercantilistic Trade Restrictiveness Index (MTRI)—is employed to average tariffs at different levels of aggregation.
The computation relies on a comparative static applied general equilibrium model (Global Trade Analysis Project—GTAP) featuring
imperfect competition as well as on the bilateral applied tariffs included in the most recent version of the GTAP database.
Results provide a different picture from what could have been expected given the widely publicized diffusion of preferential
schemes supposedly favoring developing countries exports.

We investigate a horizontally differentiated duopoly in which a public authority can either tax or subsidize firms, in order to induce duopolists to choose the socially optimal locations. The policy proposed here is such that welfare maximization is achieved by directly affecting firms' location without explicitly modifying their price behavior. 相似文献

The 1987 market crash was associated with a dramatic and permanent steepening of the implied volatility curve for equity index options, despite minimal changes in aggregate consumption. We explain these events within a general equilibrium framework in which expected endowment growth and economic uncertainty are subject to rare jumps. The arrival of a jump triggers the updating of agents' beliefs about the likelihood of future jumps, which produces a market crash and a permanent shift in option prices. Consumption and dividends remain smooth, and the model is consistent with salient features of individual stock options, equity returns, and interest rates. 相似文献
