SIZE MATTERS: THE ECONOMIC VALUE OF BEACH EROSION AND NOURISHMENT IN SOUTHERN CALIFORNIA

Despite the widespread use of nourishment in California, few studies estimate the welfare benefits of increased beach width. This paper relies on panel data funded by National Oceanic and Atmospheric Administration and other agencies. Beach choices of respondents were combined with beach attribute data to reveal how changes in width affect choice and the economic value of beach visits. We use a random‐utility approach to show that the value of beach width varies for different types of beach uses: water contact, sand‐, and pavement‐based activities. We also find that the marginal value of beach width depends on initial beach width. (JEL Q50)     

International risk sharing and commodity prices

Abstract Cole and Obstfeld (1991) exposited a classic result where equilibrium movements in the terms of trade could make ex ante risk‐sharing arrangements unnecessary: a unity elasticity of substitution across goods and production specialization. This paper extends their model to N countries and M commodities (N > M). Here the terms of trade provides insurance against commodity‐specific shocks, not country‐specific shocks. Using commodity‐level production data at the national level and world commodity prices, we document significant terms of trade variability and positive responses of nation‐specific production to terms of trade improvements. The endogenous terms of trade insurance mechanism highlighted in CO is virtually non‐existent.     

WHY IS CASH (STILL) SO ENTRENCHED? INSIGHTS FROM CANADIAN SHOPPING DIARIES

One similarity among many developed economies is the predominance of cash over electronic payments in terms of payment frequency, especially for the low‐value transactions that are the bulk of retail payments. We use the Bank of Canada's 2009 Methods‐of‐Payment Survey, which collected information on consumers' payment choices through shopping diaries, to estimate a simple model of choice between cash and other payment methods. Results suggest that the main reasons cash is still a popular payment instrument in Canada, especially for low‐value transactions, are its wide acceptance among merchants compared with other alternatives, speed and ease of use, and low marginal cost when on hand.

Economic Implications of Alternative Allocation Schemes for Emission Allowances*

For reasons of political feasibility, emission trading systems may have to rely on free initial allocation of emission allowances in order to ameliorate adverse production and employment effects in dirty industries. Against the background of an emerging European‐wide emission trading system, we examine the trade‐off between such compensation and economic efficiency under output‐based and emissions‐based allocation rules. We show that the emissions‐based allocation rule is more costly than the output‐based rule in terms of maintaining output and employment in energy‐intensive industries. When the international allowance price increases, the inferiority of emissions‐based allocation vis‐à‐vis output‐based allocation becomes more pronounced, as emission subsidies drastically restrict efficiency gains from international trade in emission allowances.     

DO CHINESE UNIONS HAVE “REAL” EFFECTS ON EMPLOYEE COMPENSATION?

In this article, we use enterprise population‐level data to investigate the effectiveness of Chinese unions in improving employee wage and nonwage compensation. We show that the effectiveness of Chinese unions stems from a “collective voice” face rather than from a “monopoly” face. The empirical findings on the effectiveness of unions are remarkable: unions in the workplace significantly improve employee wage and nonwage compensation, along with employee training. Moreover, the presence of unions within the same region and industry generates positive spillovers for employee compensation. The unions in China do have “real” effects.

On the Effect of Skewness and Kurtosis Misspecification on the Hedging Error

Using a result in Angelini and Herzel (2009a) , we measure, in terms of variance, the cost of hedging a contingent claim when the hedging portfolio is re‐balanced at a discrete set of dates. We analyse the dependence of the variance of the hedging error on the skewness and kurtosis as modeled by a Normal Inverse Gaussian model. We consider two types of strategies, the standard Black–Scholes Delta strategy and the locally variance‐optimal strategy, and we perform some robustness tests. In particular, we investigate the effect of different types of model misspecification on the performance of the hedging, like that of hedging without taking skewness into account. Computations are performed using a Fast Fourier Transform approach.     

DO TAX CUTS ENCOURAGE RENT SEEKING BY TOP CORPORATE EXECUTIVES? THEORY AND EVIDENCE

This paper explores the role of tax policy in shaping incentives for executive effort (labor supply) and rent seeking within the firm. We develop a theoretical model that distinguishes between effort and rent‐seeking responses to income taxes, and provides a framework to estimate a lower bound for the rent‐seeking response. Using executive compensation and governance data, we find that rent seeking represents an important component of the response to changes in tax rates, especially among executives in firms with the worst corporate governance.

Monotonic Knowledge Models,Cycles, Linear Versions and Auctions with Differential,Finite Information

In games of incomplete information where each player's information is represented by a partition of the state space, this paper presents a characterisation of monotonic models in terms of connected partitions and another in terms of versions . A model is monotonic if and only if there is a linear version, and this is true if and only if there is a real‐valued function on the state space such that every partition of the model is connected with respect to this function. These results help us understand the strength of the connectedness assumption on common‐value, second‐price auctions with differential, finite information. We offer a simple sufficient condition for non‐monotonicity to check if models are monotonic.     

AN EVALUATION OF FINANCIAL INCENTIVE POLICIES FOR ORGAN DONATIONS IN THE UNITED STATES

This paper examines the association between financial incentives and organ donations. Although the National Organ Transplant Act of 1984 prohibits financial compensation for organs for transplant, we focus on the impact of laws that influence the relative cost of deceased and live organ donations on the supply of organs for transplant. First, we hypothesize that states that have relatively stringent funeral regulations, which have been associated with higher whole‐body donations, will have fewer organ donations. Second, we examine the impact of two common state laws that offer financial compensation to live donors: one that allows a tax deduction for costs incurred and the other which entitles government employees up to 30 days of paid leave. We find no evidence to support that these laws affect organ donations. (JEL I11, I18)     

LACK‐OF‐RECALL AND CENTRALIZED MONETARY TRADE*

We introduce lack‐of‐recall of past transactions as an alternative assumption to anonymity in a model where trade is centralized. In environments where there is an intertemporal lack‐of‐double‐coincidence of wants problem and lack‐of‐commitment, lack‐of‐recall can give rise to monetary equilibria that dominate nonmonetary outcomes in terms of welfare.     

TRADE,STRUCTURAL REFORM,AND INSTITUTIONS IN SUB‐SAHARAN AFRICA

Sub‐Saharan African countries have traditionally lagged the rest of the developing world in terms of overall trade relative to gross domestic product. But, there is growing interest among these countries to initiate trade policies and improve quality of institutions as a way to promote trade and boost foreign direct investment. This article extends the gravity model of trade to include proxies for trade reform policy and institutional quality among the 15 countries of the Economic Community of West African States (ECOWAS) for data spanning 1984–2006. Alternative methods of estimation based on ordinary least squares, Heckman two‐step procedure, and Poisson pseudo‐maximum likelihood produce predictions that are consistent with the standard gravity model. They further highlight the evidence of restrictive trade policies and weak institutions that contribute to the failure of ECOWAS countries to boost bilateral trade. (JEL F13, F15, O19, O55)     

An Analytical Framework for Joint vs Separate Decisions by Couples in Choice Experiments: The Case of Coastal Water Quality in Tobago

This paper offers an analytical framework for analyzing joint and separate decisions by couples in the context of choice experiments for nonmarket valuation. It reports results from an attribute-based stated preference study in which members of couples are asked to conduct a choice-experiment first individually and then jointly. The choice context was the selection of which beach to visit while on vacation in Tobago. Available alternatives differed in attributes related to coastal water and beach quality such as level of coastal development and fish abundance. Tests of preference equality are reported and structured so as to identify the intra-couple decision-making patterns under taste heterogeneity with both finite and continuous mixed logit. Results from the latter suggest that women’s preferences are found to be predominant in the joint choice-experiment. Results suggest caution in using individual choice rather than joint couple choice when valuing quality changes impacting on couple activities, such as water and beach quality in Tobago, and call for further research on the topic.     

Political Pressure or Rent Seeking? The Role of Mutual Funds in China's Split Share Structure Reform

In this paper, we provide further evidence on the role of mutual funds in China using the split share structure reform as an experiment. We find no supportive evidence for the political pressure hypothesis of Firth et al. (2010), but provide a set of unique results that are consistent with rent‐seeking behaviour by mutual funds. In addition, fund‐level governance can weaken the negative relationship between compensation ratio and fund ownership. Finally, we document a specific form of private benefits that can contribute to rent‐seeking behaviour by mutual funds.     

Founders versus non-founders in large companies: financial incentives and the call for regulation

This paper is intended to question some of the premises in the ever increasing calls to regulate executive pay. We focus on founders, and extend Shleifer and Vishny’s (1989, Journal of Political Economy, 94, 461–488) manager-specific investments model by explicitly modeling managerial effort and pay performance sensitivity. Tests of this model on a data set of large companies, controlling for the endogeneity of managerial compensation, indicate that founders tend to be less responsive to performance incentives and generally more entrenched. At the same time, founders’ led firms are more valuable, supporting our predictions. This suggests that for founders, regulation of compensation may not be very effective.      

Vertically Integrated North–South Trade and the Redux Model

The paper uses the framework of Obstfeld and Rogoff's Redux model to study the impact of monetary shocks on exchange rate, terms of trade, and welfare in the context of a North–South trade. The authors show that a relative Northern monetary expansion can depreciate or appreciate its currency depending on whether the consumption elasticity of money demand and the degree of monopolistic distortion are low or high enough. This shock has asymmetric effects on welfare in such a way that “beggar‐thyself” or “beggar‐thy‐neighbor” effects always occur.     

PRICE‐PARITY ADJUSTMENTS SHOULDN'T BE A TRADE SECRET: STATE‐LEVEL PRICE PARITY AND ASSESSMENT OF COVENANTS NOT TO COMPETE ENFORCEABILITY

This paper demonstrates the importance of making regional cost adjustments and questions the validity of papers using nationwide compensation to assess noncompete enforceability and other policies without regional price‐level adjustments. Numerous papers in recent years do not incorporate the cross‐sectional analog to inflation adjustments. Using the Bureau of Economic Analysis Regional Price Parity (RPP) index, the results of a representative policy analysis study are analyzed with, and without, parity adjustment. We show that typical results demonstrating broad negative economic effects from noncompete covenants may be an artifact of using nominal, nonparity‐adjusted data. (JEL C18, R1, J31)     

Compensation Convexity without Utility Restriction

We develop an optimal contract model on the use of stock options for chief executive officer compensation under the Mirrlees–Rogerson moral hazard framework. We find that convexity, as know as, the use of stock options, can arise with a broader range of agent utility functions than allowed by Hemmer et al. ( 2000 ). We characterise the necessary conditions regarding the behaviour of the agent's marginal risk tolerance for both the concavity and convexity cases of the likelihood‐ratio function. We find stock options need to be used more intensively, when the agent displays a higher marginal risk tolerance and when the realised task output is higher.     

Some Taxation Theorems in the Hotelling Model

In this paper, we investigate the relationship between the demand ad valorem, cost ad valorem and unit taxes in terms of price, quantity and tax revenue. In particular, we prove that the Musgravian transformation holds in the Hotelling model. In addition, we show that the Suits‐Musgrave theorem must be revised as output in the Hotelling model remains invariant in the presence of different taxes. That is, for a given price instead of a given output, the tax revenue under demand ad valorem tax exceeds that under the corresponding unit tax as long as profit levels for both stores are positive, a very general assumption. The exception is when the two stores are located close to each other and transportation cost is zero. Only in this case, are tax revenues and price under both tax regimes the same. If both stores are symmetrically located, the superiority of the ad valorem tax holds true except when the two stores are located back to back. Finally the farther away the location of a firm from the end point is, the smaller the difference in tax revenues between demand ad valorem and unit tax will be: the effect of the Suits‐Musgrave theorem weakens in the presence of location clustering.     

COMPARING FEDERAL AND PRIVATE‐SECTOR WAGES WITHOUT LOGS

I use Current Population Survey data from 2005 through 2010 to compare the wages of federal employees and workers in the private sector who have similar observable characteristics. The distribution of wages differed drastically between the federal and private sectors. In particular, I find that federal employees with no more than a high school diploma earned 21% more, on average, than their private‐sector counterparts, whereas those with a professional degree or doctorate earned 23% less. Overall, the average of federal wages was about 2% higher than the average wage of similar private‐sector workers. Other researchers have found larger differences because they used log‐linearized models, which result in comparisons of geometric means. I show that arithmetic means are more relevant in the context of the relationship between a government's compensation policy and its budget. The discrepancy between differences in arithmetic and geometric means occurs because the wages of federal employees were much less dispersed than those of employees with similar characteristics in the private sector.

Exploring welfare implications of resource equivalency analysis in natural resource damage assessments

Resource equivalency analysis (REA) has become the dominant method for calculating natural resource damages for biological injuries from pollution incidents. This methodology compares resources lost as a result of an incident to benefits that can be gained from a habitat or wildlife restoration project. Compensation is evaluated in terms of resource services instead of market currency. Recently, this approach has been questioned regarding its ability to provide adequate compensation based on economic welfare principles. The following paper examines these critiques and develops a model to quantify the welfare implications of using REA when some of its implicit assumptions are violated.We focus on the situation where compensatory restoration projects provide services that are comparable to those lost as a result of an incident. We examine simulation scenarios where the public has heterogeneous preferences for resources and where resource values change over time. Using the Hicks-Kaldor criterion, we find that the traditional REA provides an acceptable approximation of aggregate compensation for a reasonably wide range of economic and biological parameter combinations.
