Linear cumulative prospect theory with applications to portfolio selection and insurance demand

Abstract The present paper combines loss attitudes and linear utility by providing an axiomatic analysis of corresponding preferences in a cumulative prospect theory (CPT) framework. In a sense we derive a two-sided variant of Yaari’s dual theory, i.e., nonlinear probability weights in the presence of linear utility. The first important difference is that utility may have a kink at the status quo, which allows for the exhibition of loss aversion. Also, we may have different probability weighting functions for gains than for losses. We apply the model to both portfolio selection and insurance demand. Our results show that CPT with linear utility has more realistic implications than the dual theory since it implies only a weakened variant of plunging.

Income Redistribution with Well-Informed Local Governments

This paper examines the problem of redistributing incomeacross jurisdictions and to mobile workers within jurisdictionswhen local governments have better information than the centralgovernment about local production conditions. Under the centralgovernments optimal policy, the subsidies or taxes that localgovernments provide to mobile workers normally depend on whetherthese governments are net recipients or net donors of interjurisdictionalincome transfers. Moreover, the public-input decisions of somelocal governments are distorted. The analysis demonstrates thatit may not be desirable to harmonize social policies across jurisdictions,even when the beneficiaries are quite mobile.

EXCHANGE RATE FUNDAMENTALS,FORECASTING, AND SPECULATION: BAYESIAN MODELS IN BLACK MARKETS

Although speculative activity is central to black markets for currency, the out‐of‐sample performance of structural models in those settings is unknown. We substantially update the literature on empirical determinants of black market rates and evaluate the out‐of‐sample performance of linear models and non‐parametric Bayesian treed Gaussian process (BTGP) models against the random walk benchmark. Fundamentals‐based models outperform the benchmark in out‐of‐sample prediction accuracy and trading rule profitability measures given future values of fundamentals. In simulated real‐time trading exercises, however, the BTGP achieves superior realized profitability, accuracy and market timing, while linear models do no better than a random walk.

Exploring the landscape of wind farm developments; local area characteristics and planning process outcomes in rural England

Despite broad public support for wind energy in principle, windfarm developments are often met with local opposition. There is theoretical, case-based and anecdotal evidence to suggest that ‘the local’ is relevant for planning process outcomes, but the nature and extent of this relevance is not so clear. We embark on an initial exploration of local factors that, on aggregate, may be of relevance to planning outcomes of proposed windfarms in rural England. Applying a broad scanning approach we use an existing small area GIS dataset of 117 variables related to education, health, demography, employment and housing. We identify a number of strong associations, and discuss to what extent these make sense in the light of existing literature on environmental equity and social capital, or throw up questions for further study. Notwithstanding the methodological caveats of this explorative study, and the scope for more in-depth analysis, our findings suggests that beyond the myriad of individual planning cases, the emerging landscape of wind energy development in England is markedly uneven, and sometimes inequitable. Evidence of the latter emerges notably through the strong significance of local democratic deficit (i.e. low voter turn-out) as a predictor of a ‘positive’ planning outcome for windfarms and the further strengthening of predictive associations at the appeal stage.     

Adäquate Wundauflagen

Wundumgebung und Wundauflagen - Die wundumgebende Haut, sofern sie intakt ist, hat eigentlich keinen direkten Einfluss auf die Wundheilung, da aber die Wundauflagen oder der Sekund?rverband auf der wundumgebenden Haut fixiert wird, ist die Beurteilung und Schutz dieser Hautareale für die Wundheilung von Bedeutung.     

On nonparametric estimation of the Schumpeterian link between innovation and firm size: Evidence from Belgium,France, and Germany

This paper analyses the Schumpeterian link between innovative activity and firm size by means of the nonparametric Nadaraya-Watson estimator and of the partially linear approach by Speckman. Four data sets referring to the manufacturing industries of three European countries are available for the analysis. We demonstrate how nonparametric methods can produce more reliable conclusions than conventional methods. For this purpose, the roles of bandwidth choice, wild bootstrap, density estimation and trimming are studied. For the German data set of 1984 and for the French data set we find that small firms and large firms are more innovative than firms of intermediate size while the relation is rather hump-shaped for Germany 1989 and decreasing for Belgium. Including an additional parametric component into the estimations based on the French data contributes considerably to the explanation of innovative activity without affecting the U-shaped link between innovation and firm size.     

Agrarpolitik in der EG

Zusammenfassung In der Wirkungsanalyse der EG-Agrarpolitik wird zwar auf eine Reihe von M?ngeln und Fehlentwicklungen hingewiesen, im ganzen aber die gemeinsame Agrarpolitik verh?ltnism?\ig günstig beurteilt. M?ngel der gemeinsamen Agrarpolitik werden weniger der Natur des Systems als dessen Handhabung zugeschrieben. Das Urteil über die EG-Agrarpolitik w?re vermutlich negativer ausgefallen, h?tte der Analyse ein st?rker am Freihandelsideal orientiertes Referenzsystem zugrunde gelegen. Als Ergebnis der Diskussion alternativer agrarpolitischer Systeme wird ein Mischsystem aus preispolitischen Ma\nahmen und sogenannten produktionsneutralen Beihilfen, die ihrem Wesen nach aber Faktorsubventionen darstellen, vorgeschlagen. Ein System personengebundener Transfers, das tats?chlich produktionsneutral w?re, wird hingegen abgelehnt. Auch hier w?re man vermutlich zu etwas anderen Ergebnissen gekommen, h?tte man der Analyse den Freihandelszustand als das relevante Referenzsystem zugrunde gelegt. Der Beitrag über Agrarpolitik und W?hrungsentwicklung enth?lt im wesentlichen überlegungen, die im Kern darauf hinauslaufen, reale Auswirkungen einer Wechselkurs?nderung von der Landwirtschaft fernzuhalten. Gesamtwirtschaftliche Argumente für die Berechtigung eines dauerhaften Grenzausgleichs enth?lt dieser Beitrag nicht.
