We describe a simple iterative method for solving large dynamic CGE models under rational expectations. Details are given for Australia's MONASH model but the approach applies to a wide range of CGE models. The method is automated in the RunMONASH Windows software, putting CGE modelling under rational expectations within the reach of non-specialist modellers. We provide an illustrative application in which MONASH results under rational expectations are compared with results under static expectations. The application and supporting software can be downloaded. Results from the application are interpreted in terms of elementary economic mechanisms. 相似文献

Dysfunctional nurse-physician communication has been linked to medication errors, patient injuries, and patient deaths. The organization is accountable for providing a context that supports effective nurse-physician communication. Organizational strategies to create such a context are synthesized from the structural, human resource, political, and cultural frameworks of organizational behavior. 相似文献

We consider a model of evolution in games in which agents occasionally receive opportunities to switch strategies, choosing between them using a probabilistic rule. Both the rate at which revision opportunities arrive and the probabilities with which each strategy is chosen are functions of current normalized payoffs. We call the aggregate dynamics induced by this model excess payoff dynamics. We show that every excess payoff dynamic is well-behaved: regardless of the underlying game, each excess payoff dynamic admits unique solution trajectories that vary continuously with the initial state, identifies rest points with Nash equilibria, and respects a basic payoff monotonicity property. We show how excess payoff dynamics can be used to construct well-behaved modifications of imitative dynamics, and relate them to two other well-behaved dynamics based on projections. 相似文献

Abstract. This paper analyses the steel safeguards applied during 2001–3. Results reveal that for shareholders of U.S. steel companies safeguards generated positive 'abnormal' returns of approximately 6%. The cancellation of the safeguards resulted in wealth gains of about 5%. Steel shareholders experienced negative abnormal returns of −5% in response to the WTO ruling that the U.S. had violated WTO law. Our results are consistent with the neoclassical view that producers gain at the expense of consumers. Also, findings indicate that downstream-consuming firms that diversify production in NAFTA countries avert some trade policy risk associated with higher steel costs caused by safeguard protection. 相似文献

Do international labor flows influence the prospects for democratization both in the countries that export their excess workers and in the countries that import them? This paper argues that emigration should have a positive effect on political liberalization in net source countries because it decreases the amount of redistribution that would occur in a more democratic regime. Conversely, immigration should have a negative effect on political liberalization in net destination countries through the same causal channel: by increasing the amount of redistribution that would occur in a more democratic regime. South Korea and Singapore are considered as illustrative examples, and the paper provides statistical evidence to support the hypothesis that emigration (immigration) has been positively (negatively) related to future political liberalization. 相似文献

This paper analyzes whether foreign direct investment (FDI) has contributed to the wide income gaps in Latin America. Panel cointegration techniques as well as regression analysis are performed to assess the impact of inward FDI stocks on income inequality among households in Latin American host countries. The panel cointegration analysis typically reveals a significant and positive effect on income inequality. There is no evidence for reverse causality. The findings are fairly robust to the choice of different estimation methods, sample selection and the period of observation. 相似文献

The combination of poor institutions and erratic macroeconomic policy, as measured by the volatility of fiscal policy, is associated with slower growth. We show that macroeconomic policy is more erratic in countries that are rich in natural resources, especially minerals and fuels, and in those that receive large aid inflows. Poor institutions also play a role. Although Africa is a major receiver of aid and exporter of natural resources, this is not purely an African phenomenon. Output volatility is not associated with slower growth after controlling for institutions and the volatility of fiscal policy. 相似文献

The excessive volatility of prices in financial markets is one of the most pressing puzzles in social science. It has led many to question economic theory, which attributes beneficial effects to markets in the allocation of risks and the aggregation of information. In exploring its causes, we investigated to what extent excessive volatility can be observed at the individual level. Economists claim that securities prices are forecasts of future outcomes. Here, we report on a simple experiment in which participants were rewarded to make the most accurate possible forecast of a canonical financial time series. We discovered excessive volatility in individual-level forecasts, paralleling the finding at the market level. Assuming that participants updated their beliefs based on reinforcement learning, we show that excess volatility emerged because of a combination of three factors. First, we found that submitted forecasts were noisy perturbations of participants’ revealed beliefs. Second, beliefs were updated using a prediction error based on submitted forecast rather than revealed past beliefs. Third, in updating beliefs, participants maladaptively decreased learning speed with prediction risk. Our results reveal formerly undocumented features in individual-level forecasting that may be critical to understand the inherent instability of financial markets and inform regulatory policy. 相似文献

We analyze the effect of the receipt of remittances on the education and health of children in Kyrgyzstan during a volatile period of their recent history, 2005–2009. The country experienced revolution in 2005 and the global financial crisis beginning in 2008. Both events impact human capital investment, and the changes vary by region of the country. We use fixed effects estimation and fixed effects, instrumental variables estimation to isolate the effects of remittances and other events on human capital. We find that boys aged 14–18 in remittances’ receiving households are less likely to be enrolled in school than other children. We also find that girls in remittances’ receiving households are more likely to be malnourished (thin). Both effects are relatively small. Remittances do not improve the human capital of children left behind. However, we do find an overall positive improvement in school enrollment among young children between 2005 and 2009 but a negative trend in enrollment among older boys and girls. Nutrition improves over time. Regional differences are apparent in these trends in nutrition and education. 相似文献
