Test–Retest Reliability of Choice Experiments in Environmental Valuation

The paper presents the results of the first test–retest study on choice experiments in environmental valuation. In a survey concerning landscape externalities of onshore wind power in central Germany, respondents answered the same five choice sets at two different points in time. Each choice set comprised three alternatives described by five attributes, and the time interval between the test and the retest was eleven months. The analysis takes place at three different levels, investigating choice consistency at the choice task level and repeatability of the latent construct utility at the level of parametric models as well as at the level of willingness-to-pay estimates. At the choice task level we observed 59?% identical choices. The parametric analysis shows that the test and retest estimates are not equal, even when we control for scale, that is, differences in the error variance. However, comparing the marginal willingness-to-pay estimates among test and retest reveals only a statistically significant difference for one of the attributes. Overall, this indicates a moderate test–retest reliability taking into account that consistency at the choice task level overlooks the stochastic nature of the process underlying discrete choice experiments.     

Asset Ownership and the Threat to Sell

In this paper the effects of selling assets are examined in a property rights model à la Grossmann, Hart and Moore. The possibility of selling an asset gives its owner a bargaining tool which can strengthen his bargaining power under certain circumstances. This offers a form of protection against opportunistic behavior in the hold-up problem, which has not yet been considered in the literature on property rights. With this model it is possible to give a rationale for unconditional joint ownership. Moreover, an explanation for privatization, outsourcing and the existence of passive outside owners can be derived within the model.     

Preferences of Scotch malt whisky consumers for changes in pesticide use and origin of barley

In a case study related to Scotch malt whisky production, this study analyses consumers’ perceptions and preferences regarding two aspects that have emerged in the debate on sustainable production and consumption, and on environmentally responsible food choice, namely (i) the use of pesticides in agriculture, and (ii) the provenance of food ingredients. We carried out a choice experiment to investigate preferences and estimate Willingness to Pay of Scotch malt whisky consumers for pesticide use restrictions and the potential impact on the production of one of its essential ingredients, barley. Using latent class models, we find that about half of the respondents are non-demanders with respect to both attributes, and only a third of the sample population are willing to pay for further pesticide restrictions. Demand for more environmentally responsible production of Scotch malt whisky is therefore limited, indicating that in the case of Scotch malt whisky, consumers are not likely to be key to driving sustainable production. With respect to barley provenance, being able to claim a 100% Scottish product could be a plausible commercial option for some producers to pursue in a competitive market. Methodologically, the scale-adjusted latent class model proved to be successful in uncovering preference heterogeneity and its sources, in including non-demanders in the analysis and in accounting for differences in scale amongst respondents.     

Option Contracts in Supply Chains

This paper considers optimal contracts in supply chains that consist of   n ≥ 2  firms and face a potential investment hold-up problem. We show that option contracts may solve the incentive problems. First, we provide case-study evidence for the use of option contracts in the semiconductor industry. As our second contribution, we generalize the earlier option contract approach by introducing continuous quantities. Third, we extend the setting to n parties. For long supply chains, the first-best allocation can be achieved if there is a particular order of renegotiations .     

Robust monetary policy in a small open economy

We study how a central bank in a small open economy should conduct monetary policy if it fears that its model is misspecified. Using a new-Keynesian model of a small open economy, we solve analytically for the optimal robust policy rule and the equilibrium dynamics, and we separately analyze the consequences of central bank robustness against misspecification concerning the determination of inflation, output, and the exchange rate. We show that an increase in the preference for robustness makes the central bank respond more aggressively or more cautiously to shocks, depending on the type of shock and the source of misspecification.     

Regressor and random-effects dependencies in multilevel models

The objectives of this paper are (1) to review methods that can be used to test for different types of random effects and regressor dependencies, (2) to present results from Monte Carlo studies designed to investigate the performance of these methods, and (3) to discuss estimation methods that can be used when some but not all of the random effects and regressor independence assumptions, are violated. Because current methods are limited in various ways, we will also present a list of open problems and suggest solutions for some of them. As we will show, the issue of regressor random-effects independence has received some attention in the econometrics literature, but this important work has had little impact on current research practices in the social and behavioral sciences.     

Co‐owned Local Government Organisations: Conditions for Strategy Development

Local governments tend to join resources and create co‐owned organisations to solve the supply of public services. From a strategic perspective on local government cooperation, this paper analyses the conditions for strategy development in a co‐owned municipal organisation. The empirical data stem from a longitudinal case study of a Swedish provider of water and sewerage services. We show that difficulties in formulating and agreeing upon strategies are not dependent on the structural form. Instead, there is an intrinsic dilemma when municipalities are to create a joint strategy at the same time as each municipality is sovereign to decide on all local matters.
