A Model of Arbitral Decision Making: Facts,Weights, and Decision Elements

This study provides a structural model of arbitral decision making that depicts arbitrators as deciding cases by ascertaining the facts, attaching weights to the facts, and combining the facts and weights to form decision elements that determine their decisions. The model further posits that arbitrators’ biographical characteristics affect their decisions by influencing their fact finding and weight assignments. It also allows for arbitrators’ characteristics to have a direct impact on their decisions. A test of the model indicates that the decision elements determine the arbitrators’ decisions but the arbitrators’ characteristics have a limited impact.     

Geroski's Stylized Facts and Mobility of Large German Manufacturing Firms

Paul Geroski has established two stylized facts with respect to theprevalence of differential changes (mobility) of indicators ofeconomic and technological performance: technologicalindicators show a larger amount of mobility than do economic indicators.We assess the two stylized facts for a sample of 392 large Germanfirms observed over the period 1981–1993 and assigned to elevenmanufacturing industries. We analyze these data with two novelmethods, Salter curves and mobility indices based on fractileMarkov chains. Our analysis supports Geroski's two stylized factsin the case of large German manufacturing firms taking account ofsectoral differences.     

Agriculture in Africa – Telling myths from facts: A synthesis

Stylized facts drive research agendas and policy debates. Yet robust stylized facts are hard to come by, and when available, often outdated. The 12 papers in this Special Issue revisit conventional wisdom on African agriculture and its farmers’ livelihoods using nationally representative surveys from the Living Standards Measurement Study-Integrated Surveys on Agriculture Initiative in six African countries. At times they simply confirm our common understanding of the topic. But they also throw up a number of surprises, redirecting policy debates while fine-tuning others. Overall, the project calls for more attention to checking and updating our common wisdom. This requires nationally representative data, and sufficient incentives among researchers and policymakers alike. Without well-grounded stylized facts, they can easily be profoundly misguided.     

Economic and Political Factors in Formal Grievance Resolution

The resolution of formal grievances is largely determined by the applicable rights of grievant and the facts surrounding disputes. However, to the extent these rights and/or facts are unclear, the granting or denial of grievances is also partially determined by economic and political factors. A model of the impact of such factors on the favor ability of grievance decisions is developed and tested. The tests yield support for the general thesis and for several specific hypotheses.     

Who Works for Whom and the UK Gender Pay Gap

This study reports novel facts about the UK gender pay gap. We use a representative, longitudinal and linked employer–employee dataset for 2002–2016. Men's average log hourly wage was 22 points higher than women's in this period. We find that 16 per cent of this raw pay gap is accounted for by estimated firm-specific wage effects. This is almost three times the amount explained by gender occupation differences. When we decompose a pre-adjusted measure of the pay gap, we find less than 1 percentage point or a 6 per cent share is accounted for by the gender allocation across high- and low-wage firms. In other words, only a small share of what is traditionally referred to as the ‘unexplained’ part of the pay gap is explained by the differences between men and women in whom they work for.     

The Structure of Licensing Contracts

Industrial organization theory has explored several issues related to licensing, but empirical analyses are extremely rare. We amass a new and detailed dataset on licensing contracts, and use it to present some simple 'facts' concerning licensing behavior. Our analysis reveals robust cross-industries differences in several contractual features, such as exclusivity, cross-licensing, ex-ante versus ex-post technology transfers, and licensing to related versus unrelated parties. We offer an interpretation of these facts based on cross-industry variation in the strength of intellectual property rights.     

Upstream-Downstream Specialization by Integrated Firms in a Partially Integrated Industry

We propose a simple model of a partially integrated industry which explicitly takes into account persistent production cost differences across upstream firms, such as one might observe in natural resource industries. The model allows us to highlight the respective roles of strategic considerations and of cost considerations in the determination of an integrated firm's interaction with the non-integrated sector of the industry and, in the end, on its relative upstream-downstream specialization. Some crude stylized facts from the world oil industry are used to motivate and illustrate the analysis.     

The Performance of US Corporations: 1981–1994

This study decomposes the performance of US public firms between 1981 and 1994 into year, industry, corporate-focus and firm effects. Performance is measured by Tobin’s q, accounting profitability, and a hybrid measure. The results show that firm effects were more important to performance than industry effects, although industry effects had a large permanent component. Corporate focus was not important. The stylized facts suggest that competitive advantages – that is, differences between direct competitors in the same industry – were at least as important as industry influences on performance. Industry influences were more predictable and sustainable than competitive advantages, however.     

House Prices and Rents: Microevidence from a Matched Data Set in Central London

I analyze a real estate agency's proprietary dataset containing tens of thousands of housing sale and rental transactions in Central London during the 2006–2012 period. I isolate 1,922 properties that were both sold and rented out within six months and measure their rent‐price ratios. I find that rent‐price ratios are lower for bigger and more central units. These stylized facts are consistent with the user cost formula and reflect differences in maintenance costs, vacancy rates, growth expectations and risk premia.     

Allocating Control over Firms: Stock Markets versus Membership Markets

The theory of the firm must explain howdecision-making powers are allocated between suppliersof capital and labor. Most large enterprises awardformal control to investors rather than workers. Isuggest here that this asymmetry can be traced in partto differences between stock markets and membershipmarkets as institutional mechanisms for allocatingcontrol over firms. The attractive theoreticalproperties of membership markets are examined, alongwith some factors that may account for their rarity inpractice. These practical difficulties help explainthe rarity of labor-managed firms themselves, alongwith various facts about their design, behavior, anddistribution across industries.     

„Bewertung von physischen Übertragungsrechten — Eine Analyse der Grenzkuppelstellen zwischen Deutschland und den Niederlanden“

The purpose of this paper is to discuss market-coherent valuation of physical transmission rights for cross-border capacities between Germany and the Netherlands. Aiming at a fair valuation of these contracts, the most important stylized facts of electricity prices such as mean reversion, spikes and correlations of regional prices have to be considered. We present two different approaches to the valuation of physical transmission rights and perform a quantitative analysis of the results. On the one hand various challenges of modeling regional price differences are discussed. On the other hand a structural undervaluation of required flexibility is indicated, which implicates missing incentives for the extension of cross border capacities.     

Firms' Cost Functions: A Reconstruction

Three empirical stylized facts characterize afirm's cost functions: AVC is generallyhorizontal; scale economies are often important;and capital usage (as well as labor usage)varies with the rate of output. In contrast ourstandard theory of diminishing marginalproducts, variable proportions, and U-shapedunit cost curves does not adequately reflectthese stylized facts of industrial reality. Explicit distinction between capital stocks andcapital flows allows a remodeling of a firm'scost curves to conform with these empirical facts.     

The Firm Size Distribution and Inter-Industry Diversification

We show that the stylized facts of the Firm Size Distribution (FSD) by age cohorts, as shown in Cabral and Mata (2003), bind within 4-digit manufacturing industries in the UK and Belgium. This paper investigates whether the time to build a portfolio of products from inter-industry diversification is a mechanism that helps explain the stylized facts of the FSD by age cohorts. We find that the degree of inter-industry diversification has a separate impact on firm size when controlling for age, amongst other factors. Using the techniques of Cabral and Mata, we find that inter-industry diversification does shift the FSD to the right, and more so in older age groups.     

Credit rating industry: A helicopter tour of stylized facts and recent theories

The recent subprime crisis and the ongoing Euro zone crisis have generated an enormous interest in the credit rating industry not only among economists but also among average citizens. As a consequence, we have seen an explosion of the economic literature on the industry. The objective of this survey is to introduce readers to the key stylized facts of the credit rating industry and to the recent theoretical economic literature on this industry.

SCREENING AND MERGER ACTIVITY*

In our paper, the target of a proposed merger, by setting a reserve price, is able to screen prospective acquirers according to their (expected) ability to generate merger‐specific synergies. Both empirical evidence and many merger models suggest that the difference between high and low‐synergy mergers becomes smaller during booms. Thus, a target's opportunity cost for sorting out relatively less fitting acquirers increases and, hence, targets screen less tightly during booms, which leads to a hike in merger activity. Our screening mechanism not only predicts that merger activity is intense during booms and subdued during recessions but is also consistent with other stylized facts about takeovers and generates novel testable predictions.

Mortgage Choice†

Mortgage choice refers to a set of problems faced by a homeowner that includes the choice of a loan-to-value ratio, the refinancing and default decisions, and the choice of mortgage instrument. This paper reviews much of the literature that has been written on the topic. It begins with a listing of the major stylized facts the literature seeks to explain. Models used to explain mortgage choice are categorized and discussed. It is argued that the relatively simple certainty model that incorporates liquidity constraints seems capable of explaining some of the stylized facts, but is unable to explain some others. The paper concludes with a discussion of three policy questions that require a better understanding of mortgage choice before they can be answered. The paper is based upon the author's Presidential Address to the American Real Estate and Urban Economics Association, which was delivered in Atlanta, Georgia on December 29, 1989.     

“Which side are you on?” A historical study of union membership composition in seven Western countries

This study uses surveys from the past 60 years to study union membership in Denmark, France, West Germany, Italy, Sweden, the United Kingdom, and the United States. We first revisit aggregate union densities finding that, for France and Italy, they were at times under- and overestimated, respectively. Second, we document the evolution of the composition of union membership in terms of gender, occupation, education, and sector. Different stylized facts emerge for different groups of countries. These facts do not lend support to the composition-based theory that attributes deunionization to deindustrialization, nor to the technological theory that predicts the exit of the high-skilled from unions.     

Theory of constraints and the combinatorial complexity of the product-mix decision

The theory of constraints (TOC) proposes that, when production is bounded by a single bottleneck, the best product mix heuristic is to select products based on their ratio of throughput per constraint use. This, however, is not true for cases when production is limited to integer quantities of final products. Four facts that go against current thought in the TOC literature are demonstrated in this paper. For example, there are cases in which the optimum product mix includes products with the lowest product margin and the lowest ratio of throughput per constraint time, simultaneously violating the margin heuristic and the TOC-derived heuristic. Such failures are due to the non-polynomial completeness (NP-completeness) of the product-mix decision problem, also demonstrated here.
