The coevolution of firms and their knowledge environment: Insights from the pharmaceutical industry

What are the most effective learning strategies for firms given the characteristics of their knowledge environment? This paper addresses this question by documenting the major changes in the knowledge environment of the pharmaceutical industry, with a particular emphasis on the period since the emergence of biotechnology, and discussing the related changes in the learning strategies of established pharmaceutical firms. Both the historical analysis and a review of the empirical research on organizational learning and knowledge transfer reveal a strong emphasis of firms on external learning through interfirm collaborations and sourcing of external knowledge. This learning strategy seems to be driven by the speed, uncertainty, and dispersion of knowledge developments in the industry. Studying the connections between the knowledge environment and the effectiveness of organizational learning processes is important to understand organizational change and adaptation, and is an area of research that deserves further attention.     

Taxation and household portfolio composition: US evidence from the 1980s and 1990s

This paper explores the relationship between household marginal income tax rates, the set of financial assets that households own, and the portfolio shares accounted for by each of these assets. It analyzes data from the 1983, 1989, 1992, 1995, and 1998 Surveys of Consumer Finances and develops a new algorithm for imputing federal marginal tax rates to households in these surveys. The empirical findings suggest that marginal tax rates have important effects on asset allocation decisions. The probability that a household owns tax-advantaged assets, such as tax-exempt bonds or assets held in tax-deferred accounts, is positively related to its tax rate on ordinary income. In addition, the portfolio share invested in corporate stock, which is taxed less heavily than interest bearing assets, is increasing in the household’s ordinary income tax rate. Holdings of heavily taxed assets, such as interest-bearing accounts, decline as a share of wealth as a household’s marginal tax rate increases.     

Public external debt,informality and production efficiency in developing countries

This paper proposes an alternative approach to investigate the non-linear effect of external debt on growth. In the theoretical part, we develop an endogenous growth model with formal and informal sectors to analyse the effect of the public external debt on the production efficiency. We show that an increase of the public external debt share increases the production efficiency through a positive externality effect. However, it generates an opposite effect via the reduction of the formal sector’s size in favour of a less efficient informal sector. The resultant effect becomes negative beyond an optimal level. Besides, we show that a large stock of public external debt reduces the production efficiency when it leads to a tight fiscal policy which reduces the formal sector size. Empirically, using a stochastic frontier technique with unobserved heterogeneity, for a panel of 27 developing countries for the period of 1970–2005, we confirm that the turning point associated to the effect of the share external public debt is apparent at 84%.     

A tale of industrial stagnation from Africa

Many African economies have experienced rather dismal industrial development since the 1980s. The consensus is that African firms lack competitiveness in a world with increasing trade openness. What determines competitiveness? A well‐known explanation is that resource endowments in Africa favour land not labour, which results in high wages, especially in comparison with ‘labour abundant’ Asian economies. This paper examines the validity of this view on the basis of the case of Sudan. We demonstrate that the lack of competitiveness of manufacturing industries is not caused by high wages. Assuming a direct relationship between labour productivity and international competitiveness, we argue that acute capacity underutilisation, caused by supply‐side constraints, lowers manufacturing productivity, which in turn negatively influences competitiveness.     

THE PRICE OF SILENCE: MARKETS FOR NOISE LICENSES AND AIRPORTS*

This article presents a market design for the management of noise pollution created by aircraft traffic around airports. A local market for noise licenses allows noise generators to compensate noise victims and to meet social acceptability. We show that the market allows the market designer to implement the social planner's optimal allocation of flights as long as the latter does not put too high a weight in his/her objective function on firms' profits compared to the disutility of noise pollution. The fact that local representatives of noise victims may be strategic players does not fundamentally alter this finding. Because of the market auctioneer's information constraints, noise licenses are likely to distribute windfall gains to residents, which alters the urban structure in the long run.     

INVESTING IN INSTITUTIONS

Robust institutional change is difficult to achieve. However, it is more difficult for some countries than others. We use data on 69 countries between 1870 and 2000 to show that political instability does not always affect growth outcomes. We then develop a simple model to explain this fact in which the likelihood that “good” institutions are abandoned during periods of political uncertainty depends on the opportunity cost of doing so. We operationalize our model by using contract intensive money as a proxy for this initial investment in growth‐enhancing institutions. Cross‐sectional and panel growth regressions support the model's predictions.     

On the performance of endogenous access pricing

Endogenous access pricing (ENAP) is an alternative to the traditional procedure of setting a fixed access price that reflects the regulator’s estimate of the supplier’s average cost of providing access. Under ENAP, the access price reflects the supplier’s actual average cost of providing access, which varies with realized industry output. We show that in addition to eliminating the need to estimate industry output accurately and avoiding a divergence between upstream revenues and costs, ENAP can enhance the incentive of a vertically integrated producer to minimize its upstream operating cost. However, ENAP can sometimes discourage surplus-enhancing investment.     

Information acquisition in conflicts

This paper considers incentives for information acquisition ahead of conflicts. First, we characterize the (unique) equilibrium of the all-pay auction between two players with one-sided asymmetric information where one player has private information about his valuation. Then, we use our results to study information acquisition prior to an all-pay auction. If the decision to acquire information is observable, but not the information received, one-sided asymmetric information can occur endogenously in equilibrium. Moreover, the cut-off values of the cost of information that determine equilibrium information acquisition are higher than those in the first best. Thus, information acquisition is excessive. In contrast, with open or covert information acquisition, the equilibrium cut-off values are as in the first best.     

Technical change,technical efficiency,and input usage in Taiwanese agricultural growth

We analyse the increase in sales of Pick 3 and Pick 4 daily numbers lottery games and other Ohio Lottery games after Ohio introduced midday drawings for the Pick 3 and Pick 4 games in August 1999. The midday drawings increased Pick 3 sales by 5%, Pick 4 sales by 12%, and total lottery sales by 2% based on our analysis of a 36-month panel dataset of Ohio lottery sales by zip code. Midday drawings raise more revenue from the strongly regressive daily numbers games. However, the introduction of midday drawings does not change the negative income elasticities of demand for numbers games in an economically meaningful manner.     

Modelling country default risk as a latent variable: a multiple indicators multiple causes approach

We study the determinants of country default risk by applying a Multiple Indicators Multiple Causes (MIMIC) model. This accounts for the fact that country default risk is an unobservable variable. Whereas existing (regression-based) approaches typically use only one of several possible country default risk indicators as the dependent variable, the MIMIC model enables us to consider several indicators at once. The simultaneous consideration of sovereign yield spreads and Standard and Poor (S&P) ratings may help to improve the identification of the latent country default risk. Our results confirm most of the literature's main findings regarding important determinants of country default risk, refute others and provide new evidence to controversial questions.
