A large body of evidence indicates that macroeconomic and financial variables are dynamically interrelated. In an international setup, we analyze the transmission mechanisms of macroeconomic shocks on the stock market of a small open economy in an increasingly integrated world. We use a time-varying vector error correction model (VECM) that allows analysis of asymmetric impacts that depend on the state of the business cycle. A special focus is directed on monetary policy surprises, where we find that foreign shocks exert a strong influence on an integrated stock market, and that the stage of the business cycle heavily affects the signals of the shocks.  相似文献

Multilateral Reforms of Trade and Environmental Policy   总被引:1,自引:0,他引:1  
The paper analyzes environmental tax policy reform using a competitive model of world trade that includes production‐generated environmental damage (pollution) and trade tariffs. The authors examine the feasibility of Pareto‐improving multilateral reforms of environmental taxes, and show that any environmental tax reform that is mutually welfare‐improving when compensating lump‐sum transfers are assumed is also welfare‐improving when a suitable tariff reform (but no transfers) is combined with the tax changes. Several specific reform proposals are developed. These results expand the feasible set of mutually improving policy proposals for international policy initiatives.  相似文献

Means-Testing the Child Benefit   总被引:1,自引:0,他引:1  
Improving the distributional impact of transfers may be costly if it reduces labor supply. In this paper we show how effects of changes in the design of the child benefit program can be examined by employing information from behavioral and non-behavioral simulations on micro data. The direct distributional effects are assessed by tax-benefit model calculations, while female labor supply responses to alternative child benefit schemes are simulated under the assumption that choices are discrete. Distributional effects after labor supply responses are also shown. The study confirms that greater targeting of the child benefit is traded against reductions in female labor supply.  相似文献

The analysis uses March Current Population Survey data to estimate state-level cross-section/time-series models of the effects of the unemployment rate on alternative poverty rates. The measures include the official headcount rate, and alternatives based higher thresholds, revised equivalence scales and income defined as inclusive and exclusive of taxes and cash and in-kind transfers. The estimated effects turn critically on the measurement approaches, both for the total sample population and for four population sub-groups. For several alternative poverty rate measures, the unemployment rate has no significant impact on poverty. By contrast, real per-capita median earnings have strong and consistently negative effects on the poverty rates of all groups studied. The findings thus provide important lessons for researchers exploring the links between economic conditions and poverty, and for policy makers developing poverty reduction strategies.  相似文献

Wage and price controls in the equilibrium sequential search model   总被引:1,自引:0,他引:1  
In this paper, we study the effects of wage and price controls on employment, output, and welfare in a simplified version of the Bénabou (J. Econom. Theory 60 (1993) 140) equilibrium sequential search model with bilateral heterogeneity. We show that a price ceiling increases output but the change in welfare depends on three effects: the reduction in aggregate search costs, the increase in surplus due to increased output, and the transfer of production to the least efficient firm. The model is formally identical to a standard equilibrium search model of the labor market so analogous results hold for the minimum wage.  相似文献

Commercial aquaculture in India has come under attack for having caused negative agricultural and environmental impacts. This paper formulates an interactive model of non-renewable and renewable resources to characterize land allocations between aquaculture and agriculture in ecologically and economically sustainable fashion. Through an empirical application, various economic and policy circumstances that affect the optimal land allocation mix are evaluated. The aquaculture industry must address two economic effects: off-site negative effects on renewable food and other coastal resources, and on-site self-pollution of shrimp ponds. Current regulatory and land-use policies are inadequate to address these effects.  相似文献

Trade negotiations between Canada and the United States are to begin in the near future. For there to be an ongoing free movement of commodities the question of nontariff barriers must be addressed in the negotiations. Livestock commodities are particularly prone to nontariff barriers due to the public health aspects of domestic regulations and the perishability of the products. Potential nontariff barriers in livestock and meat products are identified and the problems of normal negotiation procedures outlined. A proposal for an arbitration mechanism for the settlement of disputes is developed. It's essential elements are pre-approval of changes to regulations, extremely short arbitration periods and decentralized adjudication.
Les négociations de commerce entre le Canada et les États-Unis commenceront bientôt. Pour avoir un mouvement continuel des denrées, la question des barrières nontarifaires doit être adressée dans les négotiations. Les denrées bestiaux sont particulièrement portées aux barrières nontarifaires à cause des aspects de la santé publique dans les régulations domestiques et la nature périssable des produits. On identifie les barrières nontarifaires potentielles en des produits bestiaux et de viande. On indique aussi les problèmes avec les processus de négotiation normale. Une proposition pour un mécanisme d'arbitrage pour la résolution des disputes est developpée. Les elements essentiels de cette proposition sont l'approbation en avance des changements aux régulations, les périodes d'arbitration très courtes et les prononcements de jugements décentralisés.  相似文献

Forecast improvement is often approached by attempting to find the “best” model for a given situation. Less attention has been paid to the possibility of examining past prediction errors for patterns that may suggest forecast adjustments for the future. This empirical study involves one firm’s management judgment forecasts for product sales and the attempts made to improve their accuracy by removing certain types of bias. In three of the five series examined, error reduction averaging close to thirty percent occurs as a result of the adjustment procedure. The other two series proved to be relatively free from bias and were therefore not in need of the correction method described.  相似文献
