State Minimum Wage Differences: Economic Factors or Political Inclinations?

This paper examines the importance of factors that influence a state's decision to adopt an above-federal minimum wage level. Our results indicate that state political leanings are the primary factor explaining differences in state minimum wage laws since 1991. Further, state cost of living differences do not appear to influence a state's decision to increase its minimum wage above the federal level. This result is interesting since proponents of raising the minimum wage cite the rising cost of living as a principal justification for an increase. Our findings should be of special interest to economists responsible for analyzing and forecasting labor cost trends within and among states where their employers operate or plan to relocate.     

Do Imports Spur Incremental Innovation in the South?

We estimate that a one-standard-deviation increase in a firm's import penetration ratio raises its likelihood of having engaged in an incremental innovation by 4.48% using a random-sampled firm survey in China. The estimate is close to those in Gorodnichenko, Svejnar and Terrell (2010). A number of empirical strategies rule out alternative explanations as sufficient drivers of our result. Competitive pressure from imports is shown to be an underlying mechanism through which imports spur incremental innovation. We discuss how the link between imports and innovation in the South differ from that in the North.     

I Heart Logistics—Just Don’t Ask Me to Pay For It: Online Shopper Behavior in Response to a Delivery Carrier Upgrade and Subsequent Shipping Charge Increase

The provision of outstanding delivery service is increasingly critical for retailers engaged in e-commerce. As a result, many are interested in switching from their existing carrier to one that is more highly capable in order to better serve their customers. In making this switch, the retailer faces a dilemma: Better carriers cost more, so they will either have to accept a reduction in profit or increase the shipping charge to their customers. While research shows that shoppers recognize certain carriers as superior—and both theory and empirical evidence suggest that people are willing to accept certain cost-justified increases to what they are charged in a transaction—studies also show that online shoppers loathe shipping charges. Thus, what is an e-retailer to do? Through a series of vignette experiments, we examine the question of how online shoppers respond to a shipping charge increase when the retailer switches to a more highly perceived delivery carrier. Our findings show that shoppers are not particularly accepting of the switch, and while they are not likely to complain, resulting purchase intentions are notably low. Alternative strategies for implementing the carrier switch are also explored.     

On the hedging of options on exploding exchange rates

We study a novel pricing operator for complete, local martingale models. The new pricing operator guarantees put-call parity to hold for model prices and the value of a forward contract to match the buy-and-hold strategy, even if the underlying follows strict local martingale dynamics. More precisely, we discuss a change of numéraire (change of currency) technique when the underlying is only a local martingale, modelling for example an exchange rate. The new pricing operator assigns prices to contingent claims according to the minimal cost for superreplication strategies that succeed with probability one for both currencies as numéraire. Within this context, we interpret the lack of the martingale property of an exchange rate as a reflection of the possibility that the numéraire currency may devalue completely against the asset currency (hyperinflation).     

Leadership and information in a single‐shot collective action game: An experimental study

We consider a leader–follower mechanism in a collective action game, which exhibits both free riding and coordination problems. Leaders can persuade group cooperation by making a costly commitment to a project. Followers can choose to follow their leaders. The project's return can be transparent to all or only to the leaders. We show experimentally that when free riding is the dominant strategy of an informed subject, concentrating information in the hands of the leaders improves cooperation more effectively than a regime of information dispersal. The coordination problem, however, may be reduced more effectively in a regime of information dispersal. Copyright © 2010 John Wiley & Sons, Ltd.     

Destructing the hold-up

In an example of hold-up, giving the investing party the ability to destroy his relationship-specific investment can accommodate equilibria without under-investment. It suggests that destruction can be a possible incentive device in enhancing efficiency in bilateral relationships with hold-up.     

The Nasdaq-Amex Merger, Nasdaq Reforms, and the Liquidity of Small Firms

After the Nasdaq and American Stock Exchange (AMEX) merged in 1998, officials of the new entity argued that some “smaller, harder to trade” companies on Nasdaq should switch to AMEX to improve liquidity. This recommendation is based on the traditional view among academics and practitioners alike that a substantial trading cost reduction should be realized when a company switches from the multidealer Nasdaq system to the AMEX specialist system. However, in light of the 1997 Nasdaq reforms, we reexamine the validity of these arguments using data from 1996–98 on firms that switch from the Nasdaq to the AMEX or the New York Stock Exchange. Evidence from transaction costs, volatility, and stock returns shows declining benefits to switching during the sample period. Our findings indicate that the liquidity improvement from exchange listing is limited in the wake of the Nasdaq reforms of 1997.     

Economic Diplomacy and International Trade: ASEAN’s Quest to Value‐Claim

Utilising economic diplomacy theory, this study specifies a statistical model to reveal ASEAN members’ capacity to negotiate better international trade outcomes. Examining imports into ASEAN members from 134 nations between 1980 and 2001, we find that ASEAN’s diplomats were able to pursue more ‘value‐claiming’ in economic diplomacy than expected. While our results support the commonly accepted view in economic diplomacy that smaller nations are pressured to accept trade outcomes desired by larger nations, we also find support for a new perspective: smaller nations obtain more favourable trade outcomes, as members of a regional trade bloc, which cannot be achieved as individual nations. We find that ASEAN’s conversion to a fully fledged regional trade agreement in 1992 significantly enhanced this capacity. This study adds a different perspective to the substantial literature examining cases in trade and economic diplomacy.     

Is Risk Aversion Really Correlated with Wealth? How Estimated Probabilities Introduce Spurious Correlation

Economists frequently focus on correlations between wealth and risk preferences but rarely observe the probabilities needed to test this relationship empirically. These unobserved probabilities are typically estimated via profit or production functions conditioned on wealth correlates, which may leave statistical fingerprints on subsequently-estimated risk aversion coefficients and confound correlations between wealth and risk preferences. Using data from an experiment with observable probabilities, we compare risk aversion coefficients based on true probabilities with those based on probabilities estimated using standard approaches and show how estimated probabilities can change risk aversion coefficients substantially and introduce spurious correlation between risk aversion and wealth.
