Free Trade versus Autarky under Asymmetric Cournot Oligopoly

The paper compares free trade with autarky in an asymmetric multi‐country world under Cournot competition with constant returns to scale and linear demand. We derive respective conditions under which free trade will hurt a country's consumers, benefit its firms, induce it to export, increase its output and raise its welfare. We show that these conditions are linked in a clear order, with one implying the next. We further demonstrate that free trade can reduce world total output and total consumer surplus as well as world welfare. Along the way, we correct several oversights in the literature.     

Higher Tax for Top Earners

The literature can justify both increasing and decreasing marginal taxes (IMT & DMT) on top incomes under different welfare objectives and income distributions. Even when DMT are theoretically optimal, they are often politically infeasible. Then a flat tax seems to be a constrained optimal solution. We show however that, given any flat tax we can increase the total utility of a poor majority by raising the top income tax rate under a simple condition, which can be checked with empirical data. We further generalize our main results allowing different welfare weights, declining elasticity of labor supply and more tax bands.     

Educational mismatches versus skill mismatches: effects on wages, job satisfaction, and on-the-job search

Education-job mismatches are reported to have serious effectson wages and other labour market outcomes. Such results areoften cited in support of assignment theory, but can also beexplained by institutional and human capital models. To testthe assignment explanation, we examine the relation betweeneducational mismatches and skill mismatches. In line with earlierresearch, educational mismatches affect wages strongly. Contraryto the assumptions of assignment theory, this effect is notexplained by skill mismatches. Conversely, skill mismatchesare much better predictors of job satisfaction and on-the-jobsearch than are educational mismatches.

Planning in the Dark: Why Major Engineering Projects Fail to Achieve Key Goals

The arguments, analysis and observations in this paper are based on 10 years of research with partners in the European and US aerospace and defence industries. During this period, the authors were part of a team of researchers who were seeking to develop a new methodology and tool set for project management, particularly aimed at large aerospace projects. The research was motivated by the seemingly ubiquitous reality of project failure, with large engineering projects apparently always late and over budget. Here the authors focus on aerospace and defence, but the problems are generic across all branches of engineering. In their view, aerospace and defence have more excuses than most, because not only are the projects huge, but also they are globally distributed and highly complex. As work progressed, a fundamental conundrum emerged. Through discussions with project managers and assessment of the teams that were undertaking the projects, it became obvious that they were well educated, intelligent, highly motivated and very capable people. So why were so many projects going wrong? And it was not just aerospace and defence, as projects were failing in many different sectors and in numerous geographic locations. Obviously the problems were not to do with incompetence, as they were clearly so generic. As a result, the authors focused their analysis on factors inherent in the way all major projects are undertaken. The ultimate finding has been that the very technology available for managing projects today is inadequate. As argued within the paper, modern, complex projects cannot be planned and executed using 50-year-old project management tools. The paper tells the story of what is wrong with the current technology and how and why it needs to change. The authors are well aware that there are also cultural problems in project management, but many of these are exacerbated by the use of inadequate tools.     

When it comes to the crunch: What are the drivers of the US banking crisis?

This article considers how permissive regulatory conditions helped change the size and scope of the US mortgage market. Asset backed securitization facilitated an expansion of the US mortgage market and modified the structure of the value chain within which financial assets, risk and liquidity were managed. New sophisticated mortgage products, indulgent lending practices, loose credit assessment and flimsy documentation increased the probability of mortgage default in an economic downturn. US banks were not in a position to absorb mark-to-market losses on mortgage assets and goodwill impairment resulting from a credit crunch because they operate with narrow profit margins and a limited equity cushion in the balance sheet. This article questions the viability and sustainability of this banking business model.     

The Relationship between Output and Unemployment with Efficiency Wages

Abstract. We construct a stylised model of the supply side with goods and labour market imperfections to show that an economy can rationally operate at a low-effort state in which the relationship between output and unemployment is positive. We examine data from the G7 countries over 1960–2001 and find that only German data strongly favour a persistent negative relationship between the level of output and rate of unemployment. The consequence of this is that circumstances exist in which market imperfections could pose serious obstacles to the smooth working of expansionary and/or stabilisation policies and a positive demand shock might have adverse effects on employment.
