Opposing theoretical arguments exist regarding the effect of environmental regulation on financial performance. Some studies argue that environmental regulation constrains firms' abilities to exploit revenue‐enhancing or cost‐reducing opportunities. Other studies, representing the Porter hypothesis, argue that environmental regulation motivates firms to innovate, which ultimately improves financial performance. Although much of the debate focuses on long‐run effects, there are also important short‐run effects. This study provides empirical evidence regarding the short‐run and long‐run effects of Clean Water Act regulation on financial performance. To generate this evidence, we examine the effect of permitted wastewater discharge limits, on the return on sales, using panel data on publicly owned firms in the chemical manufacturing industries. We find that Clean Water Act regulation improves financial performance in both the short run and the long run with a stronger effect in the long run. These results suggest that some net benefits may be realized during a short‐run transition to comply with a tighter permitted discharge limit, with additional benefits accruing to the firm in the long run because the firm has more time to innovate.

This paper examines the variability of workers’ earnings in Canada over the period 1982–2006. We decompose the total variance of workers’ earnings into a ‘permanent’ component between workers and a ‘transitory’ earnings instability component over time for given workers. We then investigate the statistical relationships between these components and indicators for the business cycle. The most marked change in earnings variances in Canada since 1982 is the general rise in total earnings variance, which is essentially driven by a quite dramatic rise in long‐run earnings inequality. The patterns across age categories of the two variance components are almost opposite. Long‐run earnings inequality generally rises with age, but earnings instability is seen to generally decline with age, so that earnings instability is markedly highest among entry age workers. Unemployment rate effects are positive on almost all variance measures, while higher unemployment is associated with widened long‐run earnings differentials and greater short‐run earnings instability.  相似文献

This paper investigates the nature of the output–employment relationship by using the Turkish quarterly data for the period 1988–2008. Even if we fail to find a long‐run relationship between aggregate output and total employment, there are long‐run relationships for the aggregate output with non‐agricultural employment and sectoral employment levels for seven of nine sectors that we consider. However, a further investigation for the output and employment relationship within a short‐run perspective does not reveal statistically significant relationships for either total employment or non‐agriculture employment, or eight of the nine sectors that we consider. Although there are various long‐run relationships between output and employment, the short‐run links between demand and employment are weak. The various implications of this for the economy and the labour market are discussed. As a result, maintaining high levels of output in the long‐run creating demand is essential for employment generation.  相似文献

In this study, we assess the long‐run impact of labor market conditions at the time of school‐leaving on marriage and fertility outcomes. We draw data from the National Longitudinal Survey of Youth 1979. Our sample left school between 1976 and 1989, and we use variation in the state unemployment rate at the time of school‐leaving to identify persistent effects. We find that men who left school when the state unemployment rate was high are less likely to be married and have children at age 45, but are more likely to be divorced. Women, however, are more likely to have children. (JEL J1, J2)  相似文献

We assess evidence on the longer‐run effects of minimum wages, the Earned Income Tax Credit, and welfare on key economic indicators of economic self‐sufficiency in disadvantaged neighborhoods. The evidence suggests that the longer‐run effects of the Earned Income Tax Credit are to increase employment and to reduce poverty and public assistance. We also find some evidence consistent with higher welfare benefits having longer‐run adverse effects, and stronger evidence that tighter welfare time limits reduce poverty and public assistance in the longer‐run. The evidence on the longer‐run effects of the minimum wage on poverty and public assistance is not robust. (JEL J22, J23, J38)  相似文献

A model of illicit, addictive drug use is proposed when users have foresight. Impacts of drug use penalties, penalties on drug use‐related crime, support for drug user rehabilitation as well as the effects of health‐related, harm‐minimisation policies are analysed. In the short run, government policies impact only on the drug use intensities of existing addicted and casual users. Longer term policy‐induced user‐cost changes impact on new user and addict numbers through their effect on recruitment into addiction and quit dynamics. Effects of policies on user numbers, usage intensities and impacts on long‐run social costs are analysed over this long‐term horizon. The model provides a setting for analysing the long‐run effects of illicit drug management policies on the social costs of illicit drug use and allows assessment of drug use abstinence and harm minimisation policy tradeoffs.  相似文献

It is often argued that international trade is all about long‐run relationships. In this paper, we argue that this view is flawed when factor markets are characterized by turnover. Toward that end, we provide a simple dynamic model of trade with labor market turnover and show that the relationship between the economy's short‐run and long‐run behavior is more complex than in traditional trade models. For example, in the short run, the economy may produce outside of its long‐run frontier. We show that focusing on long‐run relationships can lead one to draw faulty policy conclusions, while focusing on its short‐run behavior restores sanity. The implication is that in the presence of factor market turnover, international trade issues can only be understood by studying the entire dynamic path of the economy. Long‐run relationships should be ignored.  相似文献

I explore the effect of skill‐biased technological change and unbiased technological progress on long‐run inequality using a theoretical model in which the supply of skilled and unskilled workers is endogenous. The main assumption of the model is that young agents can finance their education and become skilled workers by borrowing against their future income on an imperfect credit market. I show that whenever the rate of unbiased technological progress is sufficiently high there is no steady‐state inequality, independent of the degree of skill bias. If instead the rate of unbiased technological progress is low, then the long‐run skill premium increases with the technological skill bias. Therefore, similarly to the short run, in the long run higher technological skill bias may cause higher inequality. However, contrary to the short run, in the long run unbiased technological progress is more important than technological skill bias in determining inequality. I also discuss how the efficiency of the educational technology and the degree of financial development affect long‐run inequality.  相似文献

We develop a model of dynamic multi‐activity contests. Players simultaneously choose efforts in long‐run activities, observe each other's efforts in these activities, and then simultaneously choose efforts in short‐run activities. A player's long‐run and short‐run efforts complement each other in determining the player's probability of winning. We compare the outcomes of this two‐stage model to those of the corresponding model in which players choose efforts in all activities simultaneously. Interestingly, effort expenditures are always lower in the sequential multi‐activity contest than in the simultaneous multi‐activity contest. The implications of this result for the organization of military, litigation, innovation, academic, and sporting contests are highlighted.  相似文献

Can the owners of a firm shift a corporate profits tax to consumers? Not in the short run if the tax is stated as a proportion of profits and the firm is a profit maximizer. But what if the firm wishes to pursue a strategy other than profit maximization, say revenue maximization subject to a profit constraint? Under such a condition the firm's reaction to a tax or tax increase might be a price rise that captures part of the foregone profits. We show that firms which operate at a point on their demand curve that differs from profit maximization have an incentive to raise price in response to the tax – and that high cost firms have a greater incentive to raise price than do low cost firms. Our empirical analysis of the US beer industry confirms this finding, and sheds light on the Krzyzaniak–Musgrave analysis of the 1960s which suggested that the corporation income tax produced significant short‐run shifting.  相似文献

We construct a search model with endogenous human capital and labor participation to study the growth effects of short‐run frictions and the effectiveness of human capital policies. Employment, learning effort, and output growth increase with more effective learning, better labor‐market matching, lower job separation, or less costly vacancy creation. Although output growth, employment, vacancy creation, and learning and search effort are most responsive to changes in a human capital policy that directly affects learning effort, such a policy need not be more beneficial for welfare. The effects of human capital policies become larger as the severity of labor‐market frictions rises.  相似文献

In our model, firms choose when to set cost‐reducing investment and the government, which only has short‐run commitment power, sets an output subsidy. We show that firms that delay investment without government intervention have an incentive to invest early under policy activism, strategically underinvesting or overinvesting to obtain larger subsidies. The policy scheme thus creates a new, potentially more harmful, distortion. Under oligopoly, a firm has a weaker incentive to manipulate policy than under monopoly, which makes policy intervention less harmful. We investigate when the government may do better by adhering to laissez‐faire than by engaging in active policy intervention.  相似文献

Over the past decade, many papers have studied the effects of exchange‐rate volatility on international trade, particularly at the bilateral level for large numbers of individual industries. This is necessary because the underlying theory is ambiguous and because earlier papers failed to uncover significant results at a higher degree of aggregation. This paper examines the case of Japan and Thailand over the period from 1970 to 2010. We find that slightly more than half of 117 export industries and 54 import industries are affected by volatility in the short run. In the long run, 6 export and 2 import industries are affected positively, and 22 export and 9 import industries are affected negatively. Small Japanese export industries are more likely to be negatively affected, while imports show no differences regarding industry size. In a sectoral analysis, we find some evidence that Japanese exports of manufactures and certain machinery and transport equipment might be relatively more affected by the exchange‐rate risk. Raw material imports are least affected. These findings therefore suggest which industries might benefit most by a policy promoting a stable yen.  相似文献

This paper investigates whether there is an S‐curve in Colombia using bilateral and disaggregated quarterly data for the period 1991 to 2014. More precisely, the short‐run effects of a depreciation on the trade balance (TB ) are analyzed in 27 industries covered by the Pacific Alliance Group free trade agreement. The S‐curve found in sectors representing 30 percent of total industrial production suggests that in these cases competitive devaluations have a positive effect on the TB in the short run. Our findings have important policy implications: since only large competitive devaluations can restore TB equilibrium, industrial restructuring would appear to be a more sensible strategy, though this cannot be achieved in the short run and is instead a medium‐ to long‐term goal.  相似文献

One of the most salient features of developing economies is the existence of a large informal sector. In this paper, we use quantitative theory to study the dynamic implications of informality on wage inequality, human capital accumulation, child labor, and long‐run growth. Our model can generate transitory informality equilibria or informality‐induced poverty traps. Its calibration reveals that the case for the poverty‐trap hypothesis arises: although informality serves to protect low‐skilled workers from extreme poverty in the short run, it prevents income convergence between developed and developing nations in the long run. Then we examine the effectiveness of different development policies to exit the poverty trap. Our numerical experiments show that using means‐tested education subsidies is the most cost‐effective single policy option. However, for longer time horizons, or as the economy gets closer to the poverty trap threshold, combining means‐tested education and wage subsidies is even more effective.  相似文献

International bank portfolios constitute a large component of international country portfolios. Yet, banks' response to international macroeconomic conditions remains largely unexplored. We use a novel dataset on banks' international portfolios to answer three questions. First, what are the long‐run determinants of banks' international portfolios? Second, how do banks' international portfolios adjust to short‐run macroeconomic developments? Third, does the speed of adjustment change with the degree of financial integration? We find that, in the long‐run, market size has a positive impact on foreign assets and liabilities. An increase in the interest differential between the home and the foreign economy lowers foreign assets and increases foreign liabilities. Foreign trade has a positive impact on international bank portfolios, which is independent from the effect of other macroeconomic variables. Short‐run dynamics show heterogeneity across countries, but these dynamics can partly be explained with gravity‐type variables.  相似文献

We analyze the effectiveness of environmental policy in a framework in which households’ utility is determined by both private and social components, representing their extrinsic and intrinsic motivations to undertake green actions, respectively. Environmental policy, in the form of a subsidy aiming to incentivize the adoption of a green technology, on the one hand, directly increases households’ extrinsic motivation, while, on the other hand, indirectly decreases their intrinsic motivation. We show that, provided that the indirect effect dominates, the policy leads to crowding‐out of intrinsic motivation which ultimately undermines the effectiveness of the policy itself. Specifically, despite its positive effect on environmental outcomes in the short run, the policy will lead to a deterioration in long‐run environmental outcomes, giving rise to a reverse green‐paradox‐like outcome. Moreover, even in the case in which the direct effect dominates, provided that the indirect effect is large enough, the policy will generate a deterioration in short‐run environmental outcomes. These results clearly suggest that the optimal design of environmental policy is particularly complicated since it requires to take into account also its effects on intrinsic motivation.  相似文献

We study the effects of long‐run inflation and income taxation in an economy where households face uninsurable idiosyncratic risks. We construct a tractable competitive‐search framework that generates dispersion of prices, income and wealth. We analytically characterize the stationary equilibrium and the policy effects on individual choices. Quantitative analysis finds that monetary and fiscal policies have distinct effects on macro aggregates, such as output, savings and wealth, income and consumption inequalities. There is a hump‐shaped relationship between welfare and the respective policies. Overall, welfare is maximized by a deviation from the Friedman rule, paired with distortionary income taxation.  相似文献

Intergenerational earnings mobility is analyzed in a model where human capital is produced using schooling and parental time. In steady states more mobile societies have less inequality, but in the short run higher mobility may result from an increase in inequality. Starting from the same inequality, mobility is higher under public than under private education. A rise in income shocks, for example due to increased returns to ability, or a switch from public to private schooling both increase inequality. However, increased shocks raise mobility in the short run and do not affect it in the long run, whereas an increased role for private schooling reduces mobility in both the short and long run. That these differences may help to identify the source of changes in inequality, and other real‐world implications, are illustrated in a brief discussion of time trends and cross‐country differences.  相似文献

A key question concerning labour‐market programs is the extent to which they generate jobs for their target group at the expense of others. This effect is measured by displacement percentages. We describe a version of the MONASH model designed to quantify the effects of labour‐market programs. Our simulation results suggest that: (i) labour‐market programs can generate significant long‐run increases in employment; (ii) displacement percentages depend on how a labour‐market program affects the income trade‐off faced by target and non‐target groups between work and non‐work; and (iii) displacement percentages are larger in the short run than in the long run.  相似文献
