Vertical Integration and Efficiency: Ownership in the Swedish Sawmill Industry

This study investigates different types of vertically integrated ownership types inrelation to technical efficiency, in the Swedish sawmill industry. The theoreticalfindings connecting vertical integration and efficiency points in two directions:both in favour for non-integrated firms and in favour for fully integrated firms.In the study, significant differences between ownership types are not found. Onepossible interpretation of this result is that the integration advantages outweigh thepossible negative effects an integrated firms will have from maximising an integratedobjective function.     

A COMPARISON BETWEEN ACTUAL DISTRIBUTIONS OF ANNUAL AND LIFETIME INCOME: SWEDEN 1951–89

This paper uses register data on tax assessed income from 1951 to 1989 for a representative sample of Swedish men in order to compare the distributions of annual income and "lifetime" income. It is found that the dispersion of lifetime income is around 35 to 40 percent lower than typical cross-sections of annual income. It is income up to around 30 years of age that mainly explains this discrepancy in the magnitude of dispersions. From the age of 30 until 65 years the correlations between annual and lifetime income are quite high and the dispersion of annual income is not very much higher than the dispersion of lifetime income. An analysis of the evolution of income mobility shows that there is a slight tendency to rising mobility over time. This finding implies that the common approach to study the development of income distribution by using only annual income can be misleading.     

The pernicious effects of contaminated data in risk management

Banks hold capital to guard against unexpected surges in losses and long freezes in financial markets. The minimum level of capital is set by banking regulators as a function of the banks’ own estimates of their risk exposures. As a result, a great challenge for both banks and regulators is to validate internal risk models. We show that a large fraction of US and international banks uses contaminated data when testing their models. In particular, most banks validate their market risk model using profit-and-loss (P/L) data that include fees and commissions and intraday trading revenues. This practice is inconsistent with the definition of the employed market risk measure. Using both bank data and simulations, we find that data contamination has dramatic implications for model validation and can lead to the acceptance of misspecified risk models. Moreover, our estimates suggest that the use of contaminated data can significantly reduce (market-risk induced) regulatory capital.     

Personnel Decisions,Wage Profiles and Investment in Firms

An investment model where firms mitigate adverse hold‐up effects using hiring and personnel policies is theoretically investigated and empirically scrutinized. While no evidence for the prediction of differing worker characteristics, other than gender, across firms is found, demand (firm) side factors are evident in the hiring process. Evidence on other personnel policies is consistent with theory, which predicts firms with high‐investment expenditures resist unions, utilize more temporary and shift‐time workers and conduct more multitask training. Wages in high‐investment firms are higher, more sensitive to unemployment and experience variables that exhibit greater effects than in low‐investment firms.

Free or central banking? Liquidity and financial deepening in Sweden, 1834-1913

During Sweden’s nineteenth-century modernization, Enskilda banks contributed to economic expansion and integration by providing generally accepted means of payment beyond what would have been possible for the central bank, the Riksbank. The Riksbank was constrained by specie-convertibility requirements for Sweden’s currency. Contrary to previous arguments, however, the Enskilda banks did not operate according to free banking theory. The Enskilda banks held Riksbank notes instead of specie as base-money reserves. This arrangement led to a higher supply of formal liquidity than what would have been the case with either a free banking system or a pure deposit-based commercial banking system. The consequence for Sweden was a rapid rate of monetization and financial deepening.     

Constitutionalism and credibility in reforming economies1

There has been relatively little investigation of the effect of constitutional transformations on the economic transition in post‐communist countries. We develop a simple signalling model in which constitutionalism – a commitment to limit political power and provide judicial defence of basic rights – reinforces the credibility of pro‐market candidates’ electoral promises and boosts public support for economic reforms. These findings are tested using opinion poll data on public support for reform in Central and Eastern Europe, and in the former Soviet Union, in the 1990s. In a two‐stage procedure we show that public support for market reforms is higher in countries where incumbents have taken deliberate steps to increase political accountability and judicial independence. Public support also spurs actual economic reform.     

Flexible Integration? Mandatory and Minimum Participation Rules

For a club such as the European Union, an important question is whether a subset of the members should be allowed to form “inner clubs” and enhance cooperation. Flexible cooperation allows members to participate if and only if they benefit, but it leads to free‐riding when externalities are positive. I show that flexible cooperation is better if the heterogeneity is large and the externality small, but that rigid cooperation is the political equilibrium too often. Both regimes, however, are extreme variants of a more general system combining mandatory and minimum participation rules. For each rule, I characterize the optimum and the equilibrium.     

The Cultural Dimension of Technology Management: Lessons from the History of the Automobile

This article criticizes traditional innovation strategies for focusing too one-sidedly on technological matters. By applying the concept of 'cultural ambience', the authors attempt to show that new technologies stand a larger chance of being introduced on a large scale if, on the one hand, they can be made to fit into existing organizational networks and legal structures and, on the other hand, they are compatible with firmly established routines and perceptions. Regardless of the degree of novelty aimed at, engineers and managers have to pay attention to non-technical factors. Technology management is always cultural management. The thesis of the article is supported by brief narrative analyses of four so-called alternative automobile projects: the NSU rotary-engine car, GM's EV1, a Norwegian electric vehicle and the recently launched Smart car.
