Depression dynamics: a new estimate of the Anglo‐American manufacturing productivity gap in the interwar period1

During the interwar period the manufacturing productivity gap between the US and the UK became much larger than existing estimates suggest. In this article a new comparison of US/UK productivity levels for 1935 is presented, utilizing a more rigorous methodology to revise the widely used, but methodologically outdated, benchmark comparison by Rostas that was published in 1948. Secondly, the comparison is extended to take account of variations in input prices, and it is shown that double deflation has a substantial effect on the new benchmark, particularly at the industry level. Thirdly, labour input is adjusted for actual hours worked. US manufacturing displayed a much higher level of comparative productivity for the key industries of the second industrial revolution, such as chemicals and engineering. These results support revisionist accounts of the depression's strengthening of US productivity leadership.     

Canonical Correlation Analysis and Wiener-Granger Causality Tests: Useful Tools for the Specification of VAR Models

Dynamic multivariate models have become popular in analyzing the behavior of competitive marketing systems because they are capable of incorporating all the relationships in a competitive marketing environment. In this paper we consider VAR models, the most frequently used dynamic multivariate models. The drawback of VAR models is that a large number of parameters have to be estimated. The problem has been addressed in several articles and the usual solution is to treat only the variables of interest as endogenous while the other variables are usually included exogenously without dynamic effects. This treatment imposes restrictions on the marketing system, which requires preliminary analysis. We propose to use canonical correlation for this purpose. Canonical correlation analysis and its associated Wiener-Granger causality testing based on the canonical correlation coefficients are useful tools to test the existence of structural relationships between (lagged) consumer response and (lagged) marketing instruments. The tools are applied on data of market shares and marketing instruments in a market of a frequently purchased consumer goods.     

QUANTIFYING THE SCOPE FOR EFFICIENCY DEFENSE IN MERGER CONTROL: THE WERDEN‐FROEB‐INDEX*

This paper introduces the Werden‐Froeb Index (WFI) to assist in evaluating merger‐specific efficiencies in horizontal mergers. The index measures the weighted average reduction in marginal costs required to restore pre‐merger equilibrium prices and quantities after the (full or partial) merger is consummated. The WFI is well defined, objective and robust, and it has relatively low information requirements. We propose to use the index as a natural complement to concentration measures such as the Hirschmann‐Herfindahl Index in the assessment of horizontal mergers.     

Multiple Lenders and Corporate Distress: Evidence on Debt Restructuring

Multiple banking is a common characteristic of the corporate lending, particularly of medium-sized and large firms. However, if the firms are facing distress, multiple lenders may have serious coordination problems, as has been argued in the theoretical literature. In this paper we analyse the problems of multiple banking in borrower distress empirically. We rely on a unique panel data set that includes detailed credit-file information on distressed lending relationships in Germany. In particular, it includes information on "bank pools", a legal institution aimed at coordinating lender interests in distress. We find that the existence of small pools increases the probability of workout success and that this effect reverses when pools become large. We identify major determinants of pool formation, in particular the number of banks, the distribution of lending among banks, and the severity of the distress.     

Equilibrium Directed Search with Multiple Applications

We analyse a model of equilibrium directed search in a large labour market. Each worker, observing the wages posted at all vacancies, makes a fixed, finite number of applications, a . We allow for the possibility of ex post competition should more than one vacancy want to hire the same worker. For each a , there is a unique symmetric equilibrium in which all vacancies post the same wage. When a = 1, the common posted wage lies between the competitive and monopsony levels, and equilibrium is efficient. When a > 1, all vacancies post the monopsony wage. Some workers fail to find a job, some find a job at the monopsony wage, and some—those for whom there is competition—get the competitive wage. Equilibrium is inefficient when a > 1; in particular, there is excessive vacancy creation.
