This paper investigates the sensitivity of the RESET tests, proposed by Ramsey (1969) and modified by Thursby and Schmidt (1977), to disturbance autocorrelation in regression analysis. Porter and Kashyap (1984) show that RESET is not robust to autocorrelated disturbance when there is a highly autocorrelated regressor in the model. We show that RESET is sensitive to disturbance autocorrelation even when the regressors are not autocorrelated. We explain the findings of Thursby (1979) and Porter and Kashyap (1984) as well as our result by showing that a spurious correlation between the regressor and the disturbance is responsible for the serious size distortion of the RESET tests.

This paper examines the relationship between group size and the likelihood that a best-shot public good is voluntarily provided. Holding fixed each member's individual probability of supplying the public good, the likelihood of supply increases as the group grows. This is the size effect. However, as group size increases, the probability that each individual member supplies decreases. This is the strategic effect. The net effect of group size on the likelihood is thus ambiguous. As group size increases without bounds, the two effects are offset—the likelihood approaches a finite limit.  相似文献

In this article, we emphasised that ageing population does not systematically depress savings by drawing attention to the factors that may distort that prediction of the life‐cycle hypothesis (LCH). To demonstrate it, we used two indicators for ageing: the total and aged dependency ratios and we looked at the economic context influence on national saving evolution through considering the labour market imbalance interference. By applying the autoregressive distributed lag approach, with Tunisian data during 1970–2018, a dynamic long‐run relationship between ageing and national saving is found, although it seemed to be sensitive to the used ageing indicator and the economic context. Indeed, the LCH is proved only by the total dependence ratio whereas the aged dependence ratio puts a significant long‐run upward pressure on saving. Further, in a context of unemployment without any benefit scheme, the LCH prediction cannot be endorsed by the two indicators. Hence, the social and economic conditions limit the LCH scope, bearing out that elderly not depress systematically savings. Therefore, to sustain saving major economic and financial reforms are needed, as to postpone the retirement age, to move from pay‐as‐you‐go system towards funded pension system, to promote life insurance and to diversify the long‐run savings products.  相似文献

This paper examines the asymmetric effect of exchange rate volatility on India's cross‐border trade with its major trading partners: Japan, Germany, the United States, and China. We extend previous studies in two ways. First, we examine whether global financial crisis changes the asymmetric effect of exchange rate volatility on India's cross‐border trade. Next, we divide exchange rate volatility into quintiles and examine the effect of each quintile on cross‐border trade by using the multiple threshold nonlinear autoregressive distributed lag (MTNARDL) model. Our findings from standard nonlinear ARDL (NARDL) indicate that the asymmetric relationship between exchange rate volatility and cross‐border trade changes as a result of global financial crisis. In addition, findings from MTNARDL indicate that in short‐run, exchange rate volatility symmetrically affects India's cross‐border trade with all sample countries whereas in long‐run it asymmetrically affects cross‐border trade. Overall, these findings are very important for policy implications and open a new dimension to exchange rate volatility and trade flows.  相似文献

According to the latest IPCC reports, the frequency of hot and dry periods will increase in many regions of the world in the future. For power plant operators, the increasing possibility of water shortages is an important challenge that they have to face. Shortages of electricity due to water shortages could have an influence on industries as well as on private households. Climate change impact analyses must analyse the climate effects on power plants and possible adaptation strategies for the power generation sector. Power plants have lifetimes of several decades. Their water demand changes with climate parameters in the short- and medium-term. In the long-term, the water demand will change as old units are phased out and new generating units appear in their place.In this paper, we describe the integration of functions for the calculation of the water demand of power plants into a water resources management model. Also included are both short-term reactive and long-term planned adaptation. This integration allows us to simulate the interconnection between the water demand of power plants and water resources management, i.e. water availability. Economic evaluation functions for water shortages are also integrated into the water resources management model. This coupled model enables us to analyse scenarios of socio-economic and climate change, as well as the effects of water management actions.  相似文献

Summary. In the model presented, a buyer uses competitive bidding to facilitate her purchase of a good (the primary good of the exchange). Not included in the original purchase is the possible procurement of a good related to the original purchase: the supplementary good. The primary and supplementary goods are closely related; knowing a bidder's cost of producing the primary good implies that the buyer can infer the bidder's cost of producing the supplementary good. I show that a bidding mechanism for the primary good will fail to ensure an efficient allocation if the buyer learns the bid of the winner and the price of the supplementary good is determined through sequential bargaining.

Following the Kaleckian tradition, this paper presents a demand-ledgrowth model in which the distribution of income is fully endogenised.This is done by introducing claims on income by workers andfirms. The bargaining power of these two groups affects, throughdistribution, the patterns of accumulation and inflation. Inturn, the bargaining power of workers is affected by the rateof change of employment. The paper discusses the model's static and dynamic implications,including the effects of exogenous and induced technical progress.The model confirms all the typical Kaleckian results, includingthe fact that increases in real wages may lead to acceleratingaccumulation as well as inflation. It also produces a new result:it is possible that an increase in the rate of change of labourproductivity may not lead to an increase in the rate of changeof employment.  相似文献

The aim of this paper is to assess the possible contribution of an input-output model towards two of the basic principles of the sustainability strategy of integrated coastal zone management (ICZM) and Post-Normal Science. According to these principles, decision-support tools should offer a holistic perspective and handle high uncertainty. The difficulties in reaching sustainability are due partly to the prevailing use of “narrow-system-boundary” tools that are non-holistic. Consequently, they fail to capture important ecosystem services and ignore interdependencies between them. To comply with the basic principles, our method allows environmental assets to be evaluated in multiple units and integrates results from recent researches in natural sciences. Both enable coverage of interdependencies between ecosystem services. Thereby, we enlarge input-output modelling from the two conventional ecosystem services of sink and provisioning to the most vital ones: the supporting services. An application to the Seine estuary addresses the impacts of maritime transportation infrastructures on nursery habitats for commercial fish. The ecosystem services covered are life support and resource provisioning. Our results show that the restoration of a total of 73.7 km2 of nursery areas over the period 2004-2015 would result in a stock of sole in 2015 that exceeds the “business as usual” scenario by 44.2% (uncertainty range: 35.9%-69.9%). In spite of high restoration costs, the negative macro-economic impact is very low. However, on the sector level, a trade-off results between nurseries and three economic sectors. The quantification of such trade-offs in our model is particularly useful to public participation in decision-making.  相似文献

The main purpose of this paper is to empirically investigate whether, between 1970 and 2008, the Brazilian economy was profit-led or wage-led. To this end, we approach a canonical post-Keynesian growth model (PKGM) to estimate certain vector autoregressive (VAR) models and perform Granger non-causality tests. Three main results are extracted from the generalized impulse-response functions provided by the VAR models. First, a positive profit-share innovation affects economic growth and capacity utilization rate, both in the same direction, suggesting a profit-led pattern. Second, a profit share shock positively affects both the ratio actual/potential output, and capital accumulation, reinforcing the previous result. Third, a capacity utilization shock is shown to positively affect both output growth and capital accumulation via the accelerator effect. On the one hand, the pairwise Granger non-causality test does not provide any evidence of causality running from profit share to economic growth or capacity utilization. On the other hand, there is some evidence of Granger causality running from profit share to capital accumulation.  相似文献

This paper develops an estimable general equilibrium model of land leasing to test the extent to which information is commonly held in a village and whether village markets are efficient. Information regarding the relative farming skill of households is found to be widespread, but the assumption of perfectly efficient markets within the village is rejected. These results have ramifications for the estimation of agricultural household models and for our understanding of rural institutions. The model is derived from the primitives of the production technology, the extent of information and the distributions of assets and several household unobservables. Simultaneity and selection issues are dealt with explicitly in a two-stage maximum likelihood estimation procedure using panel data from India.  相似文献

This paper analyses the labour supply behaviour of households in Denmark and Britain. It employs models in which the preferences of individuals within the household are explicitly represented. The households are then assumed to decide on their labour supply in a Pareto Optimal fashion. Describing the structure of the household decision in this way allows preliminary results to be obtained on the internal weighting of utilities within the household.  相似文献

This paper examines the implications of a rise in the bargaining power of workers on the real wage, income distribution, and the levels of employment and output using a macroeconomic model with monopolistic competition and worker-owner Nash bargaining at the firm level. It thereby provides optimizing microfoundations to Kalecki's macroeconomic analysis of the positive effect on output of a rise in trade-union power, and contrasts it with the neoclassical view based on the diminishing marginal productivity of labor.  相似文献

We use a two-sector dynamic deterministic general equilibrium model that specifically accounts for trends among time-series variables to estimate the size of the shadow economy for the 50 U.S. states from 1999 to 2019, following Solis-Garcia and Xie (2018, 2022). This paper improves on existing measures of the state-level shadow economy (such as the multiple indicators, multiple causes (MIMIC) methodology by Wiseman (2013a)). In particular, this new measure is based on theoretical foundations, extends the previous measure to include the Great Recession, includes dollar value estimates of the shadow economy, and produces considerably more variation over time and across states. Furthermore, we explore determinants of this new shadow economy measure using a panel vector autoregressive model and find that, on average, states with higher levels of economic freedom, lower regulatory barriers, and larger real GDP have smaller shadow economies. States with bigger governments, on average, have larger shadow economies, and the effect of corruption on shadow economic activity is non-linear, with a positive initial and subsequent negative impact.  相似文献

This paper considers the role of fiscal equalization in maintaining fiscal balance. It employs a large panel of German municipalities in order to investigate the dynamic fiscal policy adjustment using a vector-error–correction model that explicitly takes account of the intertemporal budget constraint. The results confirm that a substantial part of fiscal adjustment to revenue shocks takes place by offsetting changes in intergovernmental transfers: in present-value terms about 34 cents of a permanent 1 € decrease in own revenues are compensated by subsequent changes in fiscal-equalization transfers. Hence, the contribution of intergovernmental transfers in maintaining fiscal balance is found to be two to three times larger than in the case of US municipalities investigated by Buettner and Wildasin [Buettner, T., Wildasin, D.E., 2006. The dynamics of municipal fiscal adjustment. Journal of Public Economics 90, 1115–1132]. Despite fiscal equalization, however, expenditures are not found to display smaller fluctuations in the German case.  相似文献

Technology foresight as a policy intelligence tool can offer vital inputs for policy-making in various domains. The relationship between foresight and policy-making has been presented in the literature by the policy-related functions of foresight, but the literature reflects a theoretical gap with the systematic evaluation model for the impact of foresight on policy-making. This research seeks to bridge the existing gap and uses the mixed method for this purpose. The mixed method approach used in this paper is the sequential exploratory design. First, the conceptual model is developed in the qualitative part of this research by using meta-synthesis and constant comparative method (CCM) of analysis. Second, in the quantitative part, quantitative tests are used to evaluate the dimensions and components of the developed theoretical model. The data collection tool is a questionnaire. The results confirm the proposed dimensions of the evaluation model.  相似文献

This paper constructs an RMB/USD exchange rate index and a basket currency exchange rate index. The correlation maximization of the RMB/USD and the basket currency index may determine the weight and quantity of the basket currency. The currency basket indicates that the weight of the USD is highest, whereas that of the GB Pound is the lowest. Our currency basket has a high linear dependence on that of the central bank. We found that the RMB/USD and currency basket indices have a long-term co-integration relationship according to the optimal currency weights. The results of the error-correcting model manifest as the RMB/USD exchange rate deviates from the long-term equilibrium level, wherein 76.3% will be corrected. This paper checks the prediction capacity, which indicates the good fit of the model. By using the Granger causality test the findings show that the People's Bank of China adjusts the RMB/USD exchange rate with reference to the currency basket.  相似文献

Many electric utilities, as a response to the deregulation of the electric power industry, adopted a strategy of acquiring other electric or gas utilities. We examine whether these merger and acquisition strategies create value for the utility shareholders and whether the strategies result in superior post-merger operating and stock-price performance relative to utilities that did not grow through acquisitions. We find little evidence that the mergers and acquisitions created long-term value for a fully diversified investor. Furthermore, the stock price and operating performance of the acquirers under performed the stock price and operating performance of a control portfolio of utilities that did not engage in merger activity.   相似文献

文章从分权式改革的视角分析了中国改革开放30年来的经济发展道路,总结了中国经济高速增长的主要成功经验在于政治集权下的经济分权。但是经济分权并不能有效缩小城乡、地区与贫富差距,其原因在于中国人口不能自由迁徙,对落后地区的地方政府不能实现"用脚投票"效应,从而影响了对地方政府的监督与激励作用。文章指出只有在人口自由迁徙的条件下,政治集权下的经济分权才能有效激励地方政府,特别是落后地区地方政府发展地方经济的积极性。在认清分权式改革与人口迁徙关系的基础上,正确设计下一步的改革方略,有利于中国真正走出一条大国发展之路。  相似文献
