The Effects of Weather Shocks on Economic Activity: What are the Channels of Impact?

Global temperatures have increased at a historically unprecedented pace. This paper finds that the negative effect of temperature on output in countries with hot climates runs through reduced investment, depressed labor productivity, poorer human health, and lower agricultural and industrial output. We find that hot low-income countries suffer the largest costs. In a median low-income country, aggregate output is about 2 percent lower and investment is about 10 percent lower seven years after a 1 degree increase in average annual temperature. We also find that economic development, in general, helps to shield countries from temperature shocks, with hot regions in high-income countries on average sustaining less economic damage from rising temperatures than hot regions in low-income countries.     

The Effects of Earnings Guidance on Investors’ Perceptions of Firm Credibility in a Two-Firm Setting

This study investigates how a peer firm's earnings guidance affects investors' credibility assessments of a target firm. Results suggest that when both a target firm and a peer firm provide earnings guidance, contrast effects occur such that the more accurate the earnings guidance of the target firm relative to the peer, the greater are investors' credibility assessments for the target. However, such contrast effect diminishes as the target firm's earnings guidance becomes more accurate. On the contrary, when a peer provides earnings guidance but the target firm does not, assimilation effects as opposed to contrast effects dominate investors' credibility judgments.     

Market Inertia and the Introduction of Green Products: Can Strategic Effects Justify the Porter Hypothesis?

If, according to Porter’s hypothesis, a “greener” strategy is more profitable, why may its implementation need regulatory intervention? We present a repeated Cournot duopoly where the market may exhibit inertia towards the adoption of even cost-efficient environmental goods. With consumers recognizing that a product is green only with a time lag, if a firm unilaterally adopts the green product initially loses profit due to (a) increased costs (direct effect) and (b) reduced market share (strategic effect). By imposing simultaneous adoption, regulation eliminates (b), thus enhancing long-run profitability. Through a similar mechanism a government can increase its domestic firms’ international market share and profits by forcing them to simultaneously adopt the green product.     

Harald B. Malmgren's Analysis of the Firm: lessons for modern theorists?

This paper analyses Harald B. Malmgren's neglected 1961 paper ‘Information, expectations, and the theory of the firm’, which provided the first extensive elaboration of Coase's 1937 analysis in ‘The nature of the firm’. Malmgren's primary sources of inspiration were Coase, Hayek, Richardson and Penrose. Combining these sources in a creative way allowed Malmgren to anticipate themes that have only recently been addressed in the theory of economic organization. However, there is still much to be learned from Malmgren's discussion, particularly the way in which he combined contractual and knowledge-based approaches to the firm. Moreover, Malmgren suggested that it is possible to construct an opportunism-independent approach to economic organization.     

Sad or Happy? The Effects of Emotions on Stated Preferences for Environmental Goods

A substantial literature in behavioural science and psychology shows that emotions affect human choices and values. This paper investigates whether such emotional impacts are also present in stated choice experiments for environmental goods. If this were so, it would introduce an additional element of context dependence to the welfare measures derived from such methods, and would be at odds with the rational choice model underlying welfare economics. A laboratory experiment using three different emotion treatments was combined with a stated preference choice experiment concerned with changes in coastal water quality and fish populations in New Zealand. No statistically significant effects of changes in emotional state on estimated preference parameters, willingness to pay or the randomness of choices were found. The paper concludes by questioning, why such a contrast exists with empirical findings in behavioural science.     

Paying for Pollution? How General Equilibrium Effects Undermine the “Spare the Air” Program

Policy-makers have relied on non-coercive mechanisms to achieve socially preferred outcomes in a variety of contexts when prices fail to ration scarce resources. Amid heightened concern about environmental damage and climate change, public appeals for cooperation and pecuniary incentives are frequently used to achieve resource conservation and other prosocial behavior. Yet the relative effectiveness of these two instruments is poorly understood when pecuniary incentives are small. This paper examines the extent to which free transit fares and appeals for car trip avoidance reduce car pollution on smoggy days. Using data on freeway traffic volumes and transit ridership, public appeals for cooperation are shown to have no significant effect on car trip demand. Free transit fares, however, do have a significant effect on car trip demand. But the effect is perverse in that it generates an increase in car trips and related pollution. Free fares also increase transit ridership. These results suggest that free transit rides do not induce motorists to substitute to transit, but instead subsidize regular transit rides and additional trips. Appeals for cooperation have no affect on carpooling behavior.     

Is the Income Elasticity of the Willingness to Pay for Pollution Control Constant?

How willingness to pay for environmental quality changes as incomes rise is a central question in several areas of environmental economics. This paper explores both theoretically and empirically whether or not the willingness to pay (WTP) for pollution control varies with income. Our model indicates that the income elasticity of the marginal WTP for pollution reduction is only constant under very restrictive conditions. Our empirical analysis tests the null hypothesis that the elasticity of the WTP for pollution control with respect to income is constant, employing a multi-country contingent valuation study of eutrophication reduction in the Baltic Sea. Our findings reject this hypothesis, and estimate an income elasticity of the WTP for eutrophication control of 0.1–0.2 for low-income respondents and 0.6–0.7 for high-income respondents. Thus, our empirical results suggest that the elasticity is not constant but is always less than one. This has implications for how benefits transfer exercises, and for theoretical explanations of the environmental Kuznets curve.     

Environmental Regulations,Outward FDI and Heterogeneous Firms: Are Countries Used as Pollution Havens?

We consider whether environmental regulations influence FDI outflows from a country with stringent environmental policy. We consider this issue by incorporating the predictions from the recent heterogeneous firm models of international trade into an empirical model of outward FDI by UK firms. We find that environmental regulations are not a robustly significant determinant of the internationalisation decision. In addition, we do not find robust evidence to suggest that dirtier MNEs are more likely to locate in host countries with lax environmental policy than cleaner MNEs. However, we do uncover systematic differences in the FDI behaviour of high and low environmental cost firms in other respects.     

Does the Gender of Top Managers and Owners Matter for Firm Exports?

How are export propensity and intensity affected by gender? Data from the World Bank's Enterprise Surveys (waves 2006–07, 2009–10) are used in a cross-country analysis to investigate whether export propensity and intensity differ according to the gender of top managers and entrepreneurs. Exporting is riskier than selling domestically and women, on average, tend to be more risk averse than men. Exporting entails costs, and women may have reduced access to finance compared to men. Most firms managed or solely owned by women are young and small and may have more difficulty obtaining credit. Women may self-select into routine sectors with lower mean productivity. Unlike most previous research, here the gender effect only takes into account firms where women have decision-making power. Accounting for the endogeneity of firm productivity, firm self-selection into exporting, and several factors influencing export propensity and intensity, the gender effect operates indirectly via some of those factors.     

The effects of the GSTP on trade flow: mission accomplished?

This paper investigates whether the Global System of Trade Preferences among developing countries (GSTP) achieves its intent to increase the trade of capital goods between member countries. For this purpose, trade data disaggregated by the degree of commodity differentiation and various GSTP regional dummies are employed in a gravity equation. Estimation results say that the value of trade between GSTP member countries has increased significantly since the formation of the GSTP in 1989, and the trade of differentiated commodities has increased remarkably compared with other commodities. Therefore, it can be asserted that the mission of the GSTP has been accomplished successfully.     

What is the Best Distribution for Pollution Abatement Efforts? Information for Optimizing the WFD Programs of Measures

The Water Framework Directive (WFD) has mobilized economic theory in order to encourage E.U. Member States to reach desirable environmental water pollution levels by conciliating economic and ecological interests. For this purpose, a stringent standard (“good status”) has been set. Nevertheless, it will be possible to relax this standard if it appears that total abatement costs required for reaching this “good status” exceed expected environmental benefits. This ambitious policy updates the issue of the abatement costs and environmental benefits assessment. Concerning the costs, a full discrimination of the abatement effort minimizes the total cost when the impact of polluters changes spatially, while a uniform effort can reach a pollution target in flexible ways. In this case, the increase of the degree of discrimination of the abatement effort is required only if it generates significant positive economies. Our theoretical and empirical results have shown that the discrimination advantage becomes insignificant for either very demanding or very little demanding ecological standards and varies according to the polluters’ profile. In the case of “intermediate” standards, efficiency gains become negligible with a restricted number of effort “levels”.     

Effects of Transport Regulation on the Oil Market: Does Market Power Matter?

Instruments used to regulate the consumption of oil in the transport sector include fuel taxes, biofuel requirements, and fuel‐efficiency standards. However, the effects that these have on oil consumption and price vary. If market power is present in the oil market, the directions of change in consumption and price might contrast with those in a competitive market. As a result, the market structure affects not only the effectiveness of the policy instruments used to reduce oil consumption, but also the terms of trade and carbon leakage. In particular, reduced oil consumption, as a result of increased fuel‐efficiency standards, will unambiguously increase the price of oil under a monopoly.     

Are The Costs of Proposed Environmental Regulations Overestimated? Evidence from the CFC Phaseout

Benefit-cost and cost-effectiveness analysis are often advocated fordecision making about environmental, health, and safety regulations, butthere has been little research evaluating the accuracy of prospectiveestimates of regulatory costs and benefits. Prospective estimates of themarginal cost of limiting chlorofluorocarbon (CFC) consumption in theUnited States, published shortly before and after the September 1987adoption of the Montreal Protocol, are compared with retrospectiveestimates based on realized market prices. Estimates published beforeinternational regulations were adopted (in May 1986) substantiallyoverestimate the marginal costs of limiting CFC-11 and CFC-12consumption but modestly underestimate the costs of limiting CFC-113consumption. In contrast, estimates published shortly after adoption of theProtocol (in August 1988) appear to underestimate the marginal cost oflimiting CFC consumption.     

Does the Porter Hypothesis Explain Expected Future Financial Performance? The Effect of Clean Water Regulation on Chemical Manufacturing Firms

Previous research provides opposing theoretical arguments regarding the effect of environmental regulation on financial performance. As one important argument, the Porter hypothesis claims that tighter regulation improves financial performance. This study provides empirical evidence on this debated effect. In particular, we employ panel data analysis to examine the effect of Clean Water Act regulation, as measured by permitted wastewater discharge limits, on expected future financial performance, as measured by Tobin’s q, for publicly owned firms in the chemical manufacturing industries. We find that tighter permitted discharge limits lower Tobin’s q; i.e., more stringent Clean Water Act regulation undermines expected future financial performance. By decomposing Tobin’s q into its constituent components—market value and replacement costs—and estimating each component separately, we find that tighter permitted discharge limits lower both components with a larger impact on market value, which implies that investors revise their expectations of the discounted present value of future profits in response to changes in Clean Water Act regulation.     

The Effects of Competition on Banks’ Risk Taking

We consider the joint effect of competition and deposit insurance on risk taking by banks when bank risk is unobservable to depositors. It turns out that the magnitude of risk taking depends on the structure and side of the market in which competition takes place. If the bank is a monopoly or banks are competing only in the loan market, deposit insurance has no effect on risk taking. Banks in this situation tend to take risk, although extreme risk taking is avoided. In contrast, introducing deposit insurance increases risk taking if banks are competing for deposits. Then, deposit rates become excessively high, thereby forcing banks to take extreme risks.     

Is Altruism Important for Understanding the Long-Run Effects of Social Security?

This paper quantifies the effects of social security on capital accumulation and wealth distribution in a life-cycle framework with altruistic individuals. The main findings of this paper are that the current U.S. social security system has a significant impact on capital accumulation and wealth distribution. I find that social security crowds out 8% of the capital stock of an economy without social security. This effect is driven by the distortions of labor supply due to the taxation of labor income rather than by the intergenerational redistribution of income imposed by the social security system. In contrast to previous analysis, I found that social security does not affect the savings rate of the economy. Another interesting finding is that even though the current U.S. social security system is progressive in its benefits, it may lead to a more dispersed distribution of wealth.

Consequences of the IPPC’s BAT Requirements for Emissions and Abatement Costs: A DEA Analysis on Norwegian Data

The Integrated Pollution and Prevention Control (IPPC) directive from the European Union implies that regulatory emission caps shall be set in accordance with each industry’s Best Available Techniques (BAT). The directive, which represents a harmonization of environmental regulations towards a BAT principle, is currently being implemented in all the EU member states and the states associated with the European Economic Area. The aim of this paper is to examine the effect of this implementation on emission reductions and costs, using data from Norwegian manufacturing industries. Data Envelopment Analysis (DEA) is used to construct a frontier of all efficient installations. The frontier is based on all installations within an industry that use the Best Practice Technique (BPT). We estimate the changes in emissions due to the implementation of IPPC as the difference between an installation’s actual emissions and the emissions that would occur if it operated on the frontier. The method reveals a strong potential for emission reductions. Further, estimates of short-run abatement costs indicate that considerable emission reductions can be achieved with low or no costs, but that the implementation of a strict BAT principle for all installations involves substantial costs. To the extent that the abatement costs of an installation would be excessive, IPPC includes some limited modifications of the strict BAT principle. It seems important that these modifications are fully utilized by authorities to achieve the most cost efficient implementation of the directive.      

The Hidden Costs of Wind Generation in a Thermal Power System: What Cost?

New renewable energy generation in Australia is unambiguously more expensive than thermal plant, at least when comparing direct costs. The federal government claims the 20 per cent renewable energy target will increase electricity tariffs by 4 per cent. Apart from the direct costs, critics of renewables cite additional ‘hidden costs’ arising from the intermittency of wind and the subsequent causation of ‘back‐up plant’ for system security. South Australia, where wind's market share now exceeds 17 per cent, provides a valuable case study to analyse ‘hidden costs’. The evidence is that hidden costs are trivial and the government's claim appears accurate.     

Is soccer good for you? The motivational impact of big sporting events on the unemployed

We examine the effect of salient international soccer tournaments on the motivation of unemployed individuals to search for employment using the German Socio Economic Panel 1984–2010. Exploiting the random scheduling of survey interviews, we find significant effects on motivational variables such as the intention to work or the reservation wage. Furthermore, the sporting events increase perceived health as well as worries about the general economic situation.
