Environmental policies in the United States have primarily taken the form of media-specific regulations that emphasize end-of-pipe pollution control. This can lead to the shifting of pollution across environmental media, thereby having the potential to solve one environmental problem by creating a new problem. This study uses data from 228 coal-fired power plants that report to the Toxics Release Inventory to conduct an empirical examination of the extent to which media-specific regulation has caused power plants to shift their toxic air releases to waterways, land, or transfers for offsite recycling facilities. Controlling for plant-level fixed effects, scale of production, and environmental inspections and enforcement under air regulation, this study finds that adopting tougher air pollution regulation that designates counties as being in nonattainment status with the National Ambient Air Quality Standards significantly increased toxic releases to waterways and land. 相似文献

After the recent economic turmoil, besides the severe recession that hit most European Union (EU) countries, and the resulting downward trend in inflation, foreign direct investment (FDI) levels in certain EU countries have bounced back. Hence, we evaluate the effect of deflation on intra-Eurozone FDI. Even though deflation tends to cause a negative effect on investment, low production cost opportunities may arise, thus attracting inward FDI. Using panel data that span from 2003 to 2015, we initially estimate an FDI equation that incorporates deflation as a pre-determined variable and, consequently, a two-equation model that treats both FDI and deflation as endogenous variables. Our results suggest that deflation in periphery Eurozone countries does not deter FDI flows from core to periphery Eurozone countries. 相似文献

Previous research shows that consumers’ response to price and income changes is heterogeneous. In addition, evidence from national data often does not support the classical assumption of one commodity-one price. This paper introduces a data coherent generalization to the quadratic form of the almost ideal demand system (g-QUAIDS) that incorporates the sources of heterogeneity in the demand function and allows for regional price variation. Aggregation over consumers imposes a linearization to the g-QUAIDS that requires a new set of price indices. The results from an empirical study by using microdata from the Household Income and Expenditure Survey of Iran highlight the impact of aggregation bias in relation to the level of aggregation. An investigation of the predictive power of linear versus nonlinear g-QUAIDS in different aggregation levels provides practical recommendations for consumer demand analysis. 相似文献

Ensemble methods can be used to construct a forecast distribution from a collection of point forecasts. They are used extensively in meteorology, but have received little direct attention in economics. In a real-time analysis of the ECB’s Survey of Professional Forecasters, we compare ensemble methods to histogram-based forecast distributions of GDP growth and inflation in the Euro Area. We find that ensembles perform very similarly to histograms, while being simpler to handle in practice. Given the wide availability of surveys that collect point forecasts but not histograms, these results suggest that ensembles deserve further investigation in economics. 相似文献

A structural multivariate long memory model of the US gasoline market is employed to disentangle structural shocks and to estimate the own-price elasticity of gasoline demand. Our main empirical findings are: (1) there is strong evidence of nonstationarity and mean reversion in the real price of gasoline and in gasoline consumption; (2) accounting for the degree of persistence present in the data is essential to assess the responses of these two variables to structural shocks; (3) the contributions of the different supply and demand shocks to fluctuations in the gasoline market vary across frequency ranges; and (4) long memory makes available an interesting range of convergent possibilities for gasoline demand elasticities. Our estimates suggest that after a change in prices, consumers undertake a few measures to reduce consumption in the short- and medium-run but are reluctant to implement major changes in their consumption habits. 相似文献

The current paper extends previous results on Hodrick–Prescott (HP) filtering and shows that it is possible to implement the judgement-augmented, or restricted, HP filter within the state-space framework. The implementation entails augmenting the vector of measurements and altering one of the system matrices of the state-space model for the HP filter. Restrictions can thereby be incorporated in the HP filter, making, e.g., estimation more accessible. An application to US GDP gap estimation illustrates how the restricted filter could be usefully applied in an empirical macroeconomic setting. 相似文献

This paper addresses the evolution of cooperation in a multi-agent system with agents interacting heterogeneously with each other based on the iterated prisoner’s dilemma (IPD) game. The heterogeneity of interaction is defined in two models. First, agents in a network are restricted to interacting with only their neighbors (local interaction). Second, agents are allowed to adopt different IPD strategies against different opponents (discriminative interaction). These two heterogeneous interaction scenarios are different to the classical evolutionary game, in which each agent interacts with every other agent in the population by adopting the same strategy against all opponents. Moreover, agents adapt their risk attitudes while engaging in interactions. Agents with payoffs above (or below) their aspirations will become more risk averse (or risk seeking) in subsequent interactions, wherein risk is defined as the standard deviation of one-move payoffs in the IPD game. In simulation experiments with agents using only own historical payoffs as aspirations (historical comparison), we find that the whole population can achieve a high level of cooperation via the risk attitude adaptation mechanism, in the cases of either local or discriminative interaction models. Meanwhile, when agents use the population’s average payoff as aspirations (social comparison) for adapting risk attitudes, the high level of cooperation can only be sustained in a portion of the population (i.e., partial cooperation). This finding also holds true in both of the heterogeneous scenarios. Considering that payoffs cannot be precisely estimated in a realistic IPD game, simulation experiments are also conducted with a Gaussian disturbance added to the game payoffs. The results reveal that partial cooperation in the population under social comparison is more robust to the variation in payoffs than the global cooperation under historical comparison. 相似文献

Inspired by Dornbusch’s model of exchange rate overshooting we develop a theory of stock market behaviour and its impact on
the real economy. The idea is that stock market prices overshoot and undershoot their long-run equilibrium values which are
determined by the development in the real economy. The overshooting is triggered primarily by a loose monetary policy. With
our model we explain the genesis of the global financial crisis (GFC) 2008/2009 primarily as the result of a loose monetary
policy in the USA. Following the overshooting and crash in the stock market the real economy dropped into a recession. After
modelling the interaction of three markets with different speed of adjustment—money, stocks and goods—for a closed economy
we expand it to an open economy and lastly study the spillovers of a financial market crisis between countries (from a large
to a small country) by introducing the transmission channels of external trade or cross-border financial transactions. A long-lasting
monetary easing as exhibiting by the Fed and the ECB since 2007 and 2008, respectively could—according to our model—generate
another boom-bust cycle. 相似文献
