Does Price Stability Exacerbate Labour Market Rigidities in the EMU?

How will the commitment to price stability affect labour market rigidities in the European Monetary Union? I explore a model where firms choose between fixed wage contracts (where the employer cannot lay off the worker, and the wage can only be changed by mutual consent), or contracts where employment is at will, so that either party may terminate employment (with strong similarities to temporary jobs). A fixed wage contract provides better incentives for investment and training, while employment at will facilitates efficient mobility. Inflation erodes the real value of a fixed contract wage over time, and badly matched workers are more likely to quit for other jobs. Disinflation has opposing effects on labour market rigidity: fixed wage contracts become more rigid in real terms, but fewer firms will choose fixed wage contracts.     

Costly trade,managerial myopia,and long-term investment

The costly trade theory predicts that it is much more difficult to exploit long-term private information than short-term. Thus, there is less long-term information impounded in prices. The managerial myopia theory predicts that a variety of short-term pressures, including inadequate information on long-term projects, cause asymmetrically-informed corporate managers to underinvest in long-term projects. The introduction of long-term options called LEAPS provides a natural experiment to jointly test both theories, which are otherwise difficult to test. We conduct an event study around the introduction of LEAPS for a given stock and test whether corporate investment in long-term R&D/sales increases in the years following the introduction. We find that over a two year period of time LEAPS firms increase their R&D/sales between 23% and 28% ($125–$152 million annually) compared to matching non-LEAPS firms. The difference depends on the matching technique used. Two other proxies for long-term investment find similar increases. We find that the increase is positively related to LEAPS volume. We also find that the increase is larger in firms where R&D plays a larger and more strategic role. We test if a firm becomes less likely to beat analyst's quarterly earnings forecasts after LEAPS are introduced and find support for the hypothesis. These results provide both statistically and economically significant support for the costly trade and managerial myopia theories.     

Sectoral labour supply,choice restrictions and functional form

In this paper we discuss a general framework for analysing labour supply behaviour in the presence of complicated budget and quantity constraints, of which some are unobserved. The individual's labour supply decision is viewed as a choice from a set of discrete alternatives (jobs). These jobs are characterized by attributes such as hours of work, sector‐specific wages and other sector‐specific aspects of the jobs. The labour supply model for married women is estimated on Norwegian data. Wage elasticities and the outcome of a tax reform experiment show that overall labour supply is moderately elastic, but these modest overall responses shadow for much stronger inter‐sectoral changes. Our model is compared with a discrete choice model in which the utility is assumed to be a polynomial. We show that our estimated model has a more economically sensible interpretation and fits the data as well as the alternative approach. Copyright © 2006 John Wiley & Sons, Ltd.     

Insiders and outsiders in labour market models

The monopoly union model and the wage bargaining model are analysed in light of the distinction between insiders and outsiders. It is shown that a possible outcome of the wage bargaining is the wage level where all insiders keep their job, but no outsiders are taken on. In this situation, small variations in the bargaining situation of the union will not affect the wage and employment outcome. Furthermore, it may even be the case that the union does not wish a higher wage, because this would lead to lay-offs among the insiders. Thus, the monopoly union model and the bargaining model may yield the same wage and employment levels.This paper is part of the research project Wage Formation and Unemployment at SAF Center for Applied Research at the Department of Economics, University of Oslo.

Should We Worry about Government Debt? Thoughts on Australia's COVID-19 Response

No. While the COVID-19 crisis has required a dramatic increase in debt-financed government spending, in the current conditions the benefits from this debt are unusually high and the costs unusually low. While conditions can change, the Australian Government can right now hedge against these risks by lengthening the maturity structure of government debt, even at the cost of a modest increase in its current servicing costs.     

“Large” versus “Small” Players: A Closer Look at the Dynamics of Speculative Attacks

What is the role of “large players” (e.g., hedge funds) in speculative attacks? Recent work suggests that large players move early to induce smaller agents to attack. However, many observers argue that large players move late in order to benefit from interest‐rate differentials. We propose a model in which large players can do both. Using data on currency trading by foreign (large) and local (small) players, we find that foreign players moved last in three attacks on the Norwegian krone during the 1990s. During the attack on the Swedish krona after the Russian moratorium in 1998, foreign players moved early. Gains by delaying attack were small, however, because interest rates did not increase.     

Microfinance institutions and public policy

Many governments and nongovernmental organizations have adopted policies to promote the growth of microfinance institutions (MFIs). The appropriate level and form of support for MFIs are discussed in this paper on the basis of a review of key MFI characteristics. Governments are also responsible for the regulation of MFIs; here, some principles concerning the extent and coverage of MFI regulation and supervision are developed.     

Consistency of the spatial allocation of NHS hospital resources: an econometric analysis

This paper attempts to determine econometrically the factors which affect the use of NHS hospital resources by small area level populations. The results are interpreted as revealing the implicit weights used to allocate resources between populations within a given Regional Health Authority (RHA). We test for the constancy of such weights across RHAs and examine whether the implicit weights adopted for the intraregional allocation of hospital resources are consistent with the bureaucratic rule used for inter-regional hospital resource allocation (the RAWP formula). Data were provided by six English RHAs and the explanator variables include the small Area's age/sex composition, standardized mortality rate (SMR), hospital access score and various Census-based measures of social deprivation. The major finding is that for intra-regional allocation, the influence of SMRs is constant across RHAs, but has a weight lower than that implied by the resent RAWP formula: the influence of social factors is not constant across RHAs. This paper extends the work carried out by Coopers and Lybrand for the 1986 RAWP review.     

Cost Benefit Analysis of European Air Quality Targets for Sulphur Dioxide, Nitrogen Dioxide and Fine and Suspended Particulate Matter in Cities

The European Commission has proposed air quality standards for NO₂, SO₂ and PM₁₀ to be in force by 2010. The present paper presents a study that gauged their costs and benefits. An analysis of the expected emissions for 2010 (reference emission scenario), using simplified air quality models, showed that non-compliance with these standards will occur in cities only, not in rural areas. Most compliance problems are expected for PM₁₀, least for SO₂. Central estimates of the costs to meet standards range from 21 MECU (SO₂), to 79 MECU (NO₂) to 87--225 MECU (PM₁₀). The estimated benefits are 83--3783 MECU (SO₂), 408--5900 MECU (NO₂), and 5007--51247 MECU (PM₁₀). Uncertainties are high, due to errors and incertitude in various steps of the methodology, mainly the estimation of the human health effects, in particular effects on mortality, and in the valuation of a statistical life. In the case of PM₁₀, additional uncertainty results from the small size of the air quality database. Notwithstanding the uncertainties, the indications are that the benefits exceed the costs.
