Adjustment costs and time-to-build in factor demand in the U.S. manufacturing industry

In order to explain cyclical behavior of factor demand, the static neoclassical model of the firm has been extended to include either adjustment costs (e.g. Lucas (1967)) or time-to-build considerations as in Kydland and Prescott (1982). This paper presents an intertemporal factor demand model which accounts for adjustment costs and gestation lags. The closed form solution of the model is a highly restricted vector ARMA-process that is estimated using quarterly data for the manufacturing industry in the U.S., 1960–1988. The main conclusion is that both sources of dynamics of factor demand are identifiable and found to be empirically of importance.     

Capital Mobility, Agglomeration and Corporate Tax Rates: Is the Race to the Bottom for Real?

Based on a data set for 19 OECD countries for the period 1981–2001,we estimate the impact of FDI on corporate tax rates, wherechanges in FDI are a measure for changes in capital mobility.So far the literature has been concerned with the related butrather different question as to the sensitivity of FDI to taxrates. Our article takes an opposite perspective and asks whatthe impact of capital mobility is on corporate tax rates. Indoing so, we explicitly take the role of agglomeration intoaccount. In theory, core countries can afford a higher tax ratecompared to peripheral countries. In our estimation strategy,we instrument capital mobility to deal with reverse causality.The main conclusion is that increased international capitalmobility, measured by FDI flows, implies a lower corporate taxrate. But we also find that agglomeration matters: core countrieshave a higher corporate tax rate than peripheral countries.If there is a race to the bottom, it seems that it is more realfor some countries than others.

Intertemporal market division:: A case of alternating monopoly

In this paper, we report on an equilibrium with market dominance that exists in a simple two-firm model that features neither entry barriers nor sophisticated punishment strategies. This equilibrium induces an intertemporal market division in which the two firms alternate as monopolists - despite the fact that the model also sustains a Cournot duopoly. Even when initially both firms are active in the market, the alternating monopoly reveals itself rather quickly. Moreover, it Pareto dominates the Cournot equilibrium - as it is close to the cartel outcome. Several examples of what well may be such alternating monopolies are presented.     

Can tourism be part of the decarbonized global economy? The costs and risks of alternate carbon reduction policy pathways

Global leaders agree on the need to substantially decarbonize the global economy by 2050. This paper compares potential costs associated with different policy pathways to achieve tourism sector emission reduction ambitions (?50% by 2035) and transform the sector to be part of the mid-century decarbonized economy (?70% by 2050). Investment in emissions abatement within the tourism sector, combined with strategic external carbon offsets, was found to be approximately 5% more cost effective over the period 2015–2050 than exclusive reliance on offsetting. The cost to achieve the ?50% target through abatement and strategic offsetting, while significant, represents less than 0.1% of the estimated global tourism economy in 2020 and 3.6% in 2050. Distributed equally among all tourists (international and domestic), the cost of a low-carbon tourism sector is estimated at US$11 per trip, equivalent to many current travel fees or taxes. Exclusive reliance on offsetting would expose the sector to extensive and continued carbon liability costs beyond mid-century and could be perceived as climate inaction, increasing reputational risks and the potential for less efficient regulatory interventions that could hinder sustainable tourism development. Effective tourism sector leadership is needed to develop a strategic tourism policy framework and emission measurement and reporting system.     

A dismal science; An essay on new classical economics

Summary Does new classical economics constitute a scientific achievement? Are its basic concepts demonstrably appropriate representations of fundamental characteristics of economic reality? An inspection of the relevant models shows that this is not the case. There exists hardly any empirical evidence which can be interpreted as foundational for the concepts employed in new classical microeconomics. It is more accurate to view the latter as mathematically convenient constructions which yield desired results - which often means: results that seem to be relevant for policy making. Finally, the new classical approach to macroeconomics appears to originate in substantial confusions about the nature of this subject.I am grateful to Pieter Stobbe for long and frequent discussions about economic theory which have helped to shape the views I put forward in this article. I should also like to thank Jan Marc Berk who provided research assistance. I alone am responsible for what follows.     

Is the EU ETS a Just Climate Policy?

The European Union Emissions Trading System (EU ETS) is in dire straits. Prone to design problems and suffering from the effects of the economic crises the scheme is criticised for its poor achievements. In this paper we will analyse some of the features of this situation from an ethical perspective. The major part is dedicated to the complications within each phase of the EU ETS and to the recent developments it has undergone. We will briefly discuss the remedies suggested by prominent commentators. Furthermore, any policy tool to tackle climate change should be evaluated in view of the profound equity issues that are inherent to the climate problem. We will evaluate the EU ETS according to two justice-based criteria, related to effectiveness and the distribution of the duties involved in climate change, respectively. We will conclude that the EU ETS, in its current form, clearly lacks fairness on both criteria. However, the biggest problem is the unwillingness of EU leaders to mend, what could be, a commendable climate policy tool. To that extent, we argue, those leaders are acting unjustly.     

Trade expansion with the less developed countries and employment: A case study of belgium

Zusammenfassung Handelsausweitung mit Entwicklungsl?ndern und Besch?ftigung. Eine Fallstudie für Belgien. — Die Hauptergebnisse dieser Studie k?nnen wie folgt zusammengefa\t werden: Eine ausgeglichene Ausweitung des belgischen Handels mit Entwicklungsl?ndern hat für die Gesamtnachfrage nach Arbeit in der belgischen Volkswirtschaft einen schwachen negativen Effekt. Dieser schwache Gesamteffekt verbirgt indessen bedeutende Verschiebungen in der sektoralen Nachfrage nach Arbeitskr?ften. Das bedeutet, da\ eine ausgeglichene Ausweitung des Handels mit Entwicklungsl?ndern ein hinreichendes Ma\ an sektoraler Faktormobilit?t verlangt, wenn l?ngerfristige Arbeitslosigkeit vermieden werden soll. Au\erdem ist angesichts der bedeutenden Unterschiede zwischen dem Faktorgehalt von Importen aus Entwicklungsl?ndern und von belgischen Exporten in die Entwicklungsl?nder bei einer Handelsausweitung mit Entwicklungsl?ndern eine erhebliche ?nderung der relativen Faktorpreise erforderlich, wenn Vollbesch?ftigung erhalten bleiben soll. Es ist wichtig, auf die Grenzen der vorliegenden Studie hinzuweisen. Erstens dürfte eine Ausweitung des Handels mit Entwicklungsl?ndern Auswirkungen auf die Technologie haben. Diese Wirkungen konnten, da wir fixe technische Koeffizienten benutzten, nicht erfa\t werden. Zweitens wurde angenommen, da\ die Ausweitung des Handels mit Entwicklungsl?ndern in Form eines ausgeglichenen sektoralen Anstiegs der Exporte und Importe (auf der Basis der gegenw?rtigen Anteile des belgischen Handels mit Entwicklungsl?ndern) erfolgen würde. Es ist aber wahrscheinlich, da\ die Ausweitung des Handels auf wenige Sektoren konzentriert sein wird. Das k?nnte die sektoralen Besch?ftigungsprobleme versch?rfen. Drittens wurden die relativen Preiseffekte eines verst?rkten Handels mit Entwicklungsl?ndern vernachl?ssigt. Insbesondere wurden die Wirkungen dieser relativen Preise auf die Konsumstruktur nicht berücksichtigt.

Résumé L’expansion de commerce extérieur avec les pays moins developpés et l’emploi. Une étude exemplaire de la Belgique. — Les résultats essentielles de cette étude peuvent être résumés de la manière suivante. Une expansion balancée du commerce extérieur belge avec les pays en voie de développement (PVD) à une petite influence négative sur la demande totale sur la main d’oeuvre dans l’économie belge. Cet effet petit aggrégé, cependant, cache des importants mouvements opposés concernant les demandes sectorielles sur la main d’oeuvre. Comme résultat, une expansion balancée du commerce extérieur avec les PVD rend nécessaire un degré suffisant de la mobilité de facteur sectorielle si un ch?mage prolongé devrait être évité. Additionellement, si on considère les différences importantes des contenus de facteur entre les importations des PVD et les exportations belges vers les PVD, une commerce augmenté avec les PVD rend nécessaire des changes significants des prix de facteur relatifs dans la Belgique si le plein emploi devrait être maintenu. Il est important de souligner les limitations de l’étude présente. Premièrement, une expansion de commerce avec les PVD a probablement des effets sur la technologie. Ces effects ne pouvaient pas être considérés à cause des coéfficients techniques fixes. Deuxièmement, nous avons supposé que l’expansion de commerce avec les PVD se passe par une augmentation sectorielle balancée des exportations et des importations en utilisant le rapport présent du commerce des PVD avec la Belgique. Il est cependant probable que l’expansion du commerce extérieur avec les PVD se concentra dans quelques secteurs. Cela pourrait puis aggraver les problèmes d’emploi sectoriel. Troisièmement, nous n’avons pas regardé les effets des prix relatifs du commerce augmenté avec les PVD. Particulièrement, nous n’avons pas considéré les effets de ces prix relatifs sur les structures de consommation.

Resumen Expansión del comercio con palses en desarrollo y el empleo. Un estudio del caso de Bélgica. — Los principales resultados de este estudio pueden resumirse como sigue. Una expansión equilibrada del comercio belga con los países en desarrollo tiene un impacto negativo reducido sobre la demanda por trabajo en la economía belga. Este peque?o efecto agregativo, sin embargo, esconde importantes traslados opuestos en las demandas sectoriales por trabajo. Como resultado, una expansión balanceada del comercio con los países en desarrollo requière de un grado suficiente de movilidad sectorial de factores, si se quiere evitar un desempleo prolongado. Adicionalmente, dadas las importantes diferencias en el contenido de factores entre importaciones de paises en desarrollo y exportaciones belgas hacia ellos, un aumento del comercio con los paises en desarrollo requiere de cambios significativos en los precios relativos en Bélgica, si se quiere mantener el pleno empleo. Es importante subrayar las limitaciones del presente estudio. Primero, una expansión del comercio con los países en desarrollo probablemente tendrá efectos sobre la tecnología. Estos efectos no pudieron captarse, ya que se usaron coeficientes técnicos fijos. Segundo, se asumió que la expansión del comercio con los países en desarrollo iba a tener la forma de un crecimiento sectorial balanceado de exportaciones e importaciones usando la participación presente de los países en desarrollo en el comercio con Bélgica. Es probable, sin embargo, que la expansión del comercio con los paises en desarrollo se concentre sobre unos pocos sectores. Esto puede agravar entonces los problemas sectoriales de empleo. Tercero, los electos de precios relativos como consecuencia de la expansión del comercio con los países en desarrollo fueron desatendidos. En particular, no se tomaron en cuenta los efectos de estos precios relativos sobre los patrones de consumo.

     

Heterogeneous Impact of Soil Contamination on Farmland Prices in the Belgian Campine Region: Evidence from Unconditional Quantile Regressions

We estimate a hedonic-pricing model using geo-coded farmland-transaction data from the Campine region, situated in the north-east of Belgium. Unlike previous hedonic studies, we use the method of unconditional quantile regression (Firpo et al., in Econometrica 77(3):953–973, 2009). An important advantage of this new method over the traditional conditional quantile regression (Koenker and Bassett, in Econometrica 46(1):33–50, 1978) is that it allows for the estimation of potentially heterogeneous effects of cadmium pollution along the entire (unconditional) distribution of farmland prices. Using a threshold specification of the hedonic-pricing model, we find evidence of a U-shaped valuation pattern, where cadmium pollution of the soil has a negative and significant impact on prices only in the middle range of the distribution, insofar as cadmium concentrations are above the regulatory standard of 2 parts per million for agricultural land. Results obtained from a probit model to classify land plots into different price segments further suggest that the heterogeneous impact of soil pollution on price can be directly related to the variety of amenities that farmland provides.     

Homotopy methods to compute equilibria in game theory

This paper presents a survey of the use of homotopy methods in game theory. Homotopies allow for a robust computation of game-theoretic equilibria and their refinements. Homotopies are also suitable to compute equilibria that are selected by various selection theories. We present the relevant techniques underlying homotopy algorithms. We give detailed expositions of the Lemke–Howson algorithm and the van den Elzen–Talman algorithm to compute Nash equilibria in 2-person games, and the Herings–van den Elzen, Herings–Peeters, and McKelvey–Palfrey algorithms to compute Nash equilibria in general n-person games. We explain how the main ideas can be extended to compute equilibria in extensive form and dynamic games, and how homotopies can be used to compute all Nash equilibria.
