Wealth and sustainable development: the role of David Pearce

Green net national product was thought to be one way of measuring sustainable income. However, David Pearce understood that a better measure of sustainable development was to look at what a generation is leaving in form of capital assets to later generations. In this article, his arguments and insights are highlighted against recent theoretical advances.     

Assessing Preference Change on the US Supreme Court

The foundation upon which accounts of policy-motivated behaviorof Supreme Court justices are built consists of assumptionsabout the policy preferences of the justices. To date, mostscholars have assumed that the policy positions of Supreme Courtjustices remain consistent throughout the course of their careersand most measures of judicial ideology—such as Segal andCover scores—are time invariant. On its face, this assumptionis reasonable; Supreme Court justices serve with life tenureand are typically appointed after serving in other politicalor judicial roles. However, it is also possible that the worldviews,and thus the policy positions, of justices evolve through thecourse of their careers. In this article we use a Bayesian dynamicideal point model to investigate preference change on the USSupreme Court. The model allows for justices' ideal points tochange over time in a smooth fashion. We focus our attentionon the 16 justices who served for 10 or more terms and completedtheir service between the 1937 and 2003 terms. The results arestriking—14 of these 16 justices exhibit significant preferencechange. This has profound implications for the use of time-invariantpreference measures in applied work.     

The impact of European firms＇ economic conditions and financial performance on accounting quality

In this study the authors analyse the possible effect of firms＇ economic conditions and financial performance on accounting quality. Bradshaw, et al. （2004）, Gelos ＆ WEI （2005） stated that financial reporting quality is fundamental for investors and it affects international capital movements. Following Schipper ＆ Vicent （2003）, the authors estimated accounting quality by abnormal accruals and earnings persistence. The authors＇ contribution consists of investigating a huge number of firms from 17 European countries using unbalanced panel data. The authors found evidence that economic conditions affect accounting quality： big firms and those with high current earnings exhibit better financial information. These results are robust because they do not depend on the accounting quality proxy, even when the authors estimated regression with economical and financial factors alone or together. Financial performance does not seem to affect accounting quality. However, this relation is not linear because in high leveraged firms, the capital structure becomes determinant.     

On the Delegation of Powers: With Special Emphasis on Central and Eastern Europe

Elected politicians can choose to decide themselves or to delegate competence. Delegation can occur in the constitutional stage, but is most common in the post-constitutional stage. Furthermore, domestic delegation can be distinguished from international delegation. The authors propose to analyze both delegation decisions within a unified framework and apply it to eight countries of Central and Eastern Europe that have experienced substantial constitutional change recently. The main differences among these countries with regard to delegation are portrayed, their origins are traced and their effects analyzed.     

Outsourcing, Imports and Labour Demand

This paper examines the effects of purchased services and imported intermediate materials on the labour demand for different skills in German manufacturing sectors. We derive and estimate a factor demand system based on the generalised Box–Cox cost function nesting both the normalised quadratic and the translog functional form. We find that the impacts of output and capital growth are more important in explaining the demand for heterogeneous labour than substitution effects between labour and non–labour inputs. Similarly, the increasing use of both imported materials and purchased services is a consequence of output growth rather than input substitution.
