Meta-Functional Benefit Transfer for Wetland Valuation: Making the Most of Small Samples

This study applies functional Benefit Transfer via Meta-Regression Modeling to derive valuation estimates for wetlands in an actual policy setting of proposed groundwater transfers in Eastern Nevada. We illustrate how Bayesian estimation techniques can be used to overcome small sample problems notoriously present in Meta-functional Benefit Transfer. The highlights of our methodology are: (i) The hierarchical modeling of heteroskedasticity; (ii) The ability to incorporate additional information via refined priors; and (ii) The derivation of measures of model performance with the corresponding option of model-averaged Benefit Transfer predictions. Our results indicate that economic losses associated with the disappearance of these wetlands can be substantial and that primary valuation studies are warranted.      

The inflation rates may accelerate after all: panel evidence from 19 OECD economies

The stationarity of inflation has many important economic implications. Most panel-based empirical studies do not handle cross-sectional dependence, which will result in power distortion. This paper applies a nonlinear IV estimator to calculate the test statistic of panel unit root (Chang in J Econom 110:261–292, 2002), which accounts for general cross-sectional correlation. Using monthly inflation rates, two statistics proposed by Im et al. (J Econom 115:53–74, 2003) reject the unit root; however, the nonlinear IV statistic accepts the unit root. That is, the ignored cross-sectional correlation may lead to over-rejection of the unit root null. In a nutshell, unlike current literature, the inflation rates may accelerate after all.     

A comprehensive German business cycle chronology

Business cycle chronologies offer reference points for empirical studies used as benchmarks for business cycle and recession theory. A quasi-official chronology exists for the US economy, but not for most European countries, including Germany. While most papers dealing with business cycle dates rely on one specific method, I present and discuss a number of different dating approaches based on the classical business cycle. These are applied to German GDP data comprising 1970–2006. Finally, based on the results of the different methods, a consensus business cycle chronology for the German economy is suggested.     

Task assignment and organizational form

This paper shows that a firm prefers a process-based task assignment compared to a function-based one if the tasks are from functional areas which are neither too complementary nor too substitutable. We consider several projects (processes) with contributions from several functional areas. The organization can be structured along processes like product lines (M-form) or along functional areas like marketing or production (U-form). The U-form enables cost savings due to specialization or scale economies. The more effective incentives under the M-form might outweigh these savings if the functions are neither too complementary nor too substitutable.      

The critical discount factor as a measure for cartel stability?

This paper considers the stability of tacit collusion in price setting duopolies with repeated interaction. The minimum discount factor above which tacit collusion can be sustained in a subgame perfect equilibrium is called the critical discount factor δ*. In addition, δ* is often used as an intuitive measure for the stability of a tacit cartel, assuming that a collusive equilibrium is more difficult to sustain when δ* increases. However, according to standard theory the distance δ − δ* between the actual and the critical discount factor does not matter for stability as long as δ > δ*. This paper contributes experimental evidence that supports the intuitive idea that a larger critical discount factor makes collusion a less likely outcome.      

Monetary policy and multiple equilibria with constrained investment and externalities

This paper focuses on two mechanisms under which interest-rate feed-back rules induce local indeterminacy in a closed economy with capital accumulation: arbitrage activity and the pricing channel. It shows that constrained investment, in the sense that it requires liquidity or that adjustment to the stock of capital is costly, is enough to induce indeterminacy if monetary policy follows a strictly passive interest rate rule. Determinacy of equilibrium is ensured under an active monetary policy stance. These results change when production externalities are introduced into the model so as to mimic the pricing channel in New Keynesian models. In this case, a policy stance that ensures determinacy is either active or strictly passive. In view of the contradicting results for the passive stance and the similar results for the active stance it is recommended that central banks act according to the active stance.     

Competitive sprawl

Sprawl and low urban density are often considered challenges to the vitality and efficiency of metropolitan areas. Utilizing a difference equation approach to endogenize density choices, this paper examines how competition between new cities causes development to occur too quickly compared to welfare maximizing development. Early development causes land to be sold in larger lots to a smaller number of buyers, causing lower population density. Competition in a timing game among developers causes early development, lower population density and lower capital density. I would like to thank James Peck, Don Haurin, Bruce Weinberg, David Hineline and an anonymous referee for comments on earlier drafts.     

Escalating penalties for repeat offenders: a note on the role of information

The severity of the sanction for a given offense is often determined by the offense history of the offender. We establish that this policy can be welfare-maximizing if individuals are imperfectly informed about the magnitude of the sanction. Imperfect information distorts individuals’ perception of the expected sanction of the first offense. Once detected, individuals learn about the sanction applicable to their act, making this argument less relevant for consecutive offenses.
