    Public goods and optimal paternalism under present-biased preferences2011In: Economics Letters, ISSN 0165-1765, E-ISSN 1873-7374, Vol. 113, no 1, p. 54-57Article in journal (Refereed)
    Abstract [en]

    This paper concerns the provision of a state-variable public good in a two-type model under present-biased consumer preferences. The preference for immediate gratification facing the high-ability type weakens the incentive to adjust public provision in response to the self-selection constraint.

    Outsourcing and optimal nonlinear taxation: a note2009In: Economics Letters, ISSN 0165-1765, E-ISSN 1873-7374, Vol. 102, no 2, p. 135-137Article in journal (Refereed)
    Abstract [en]

    This paper concerns optimal taxation and outsourcing. If the government has a direct instrument for taxing outsourcing, the policy rules for marginal income taxation remain as in the standard model. Otherwise, outsourcing contributes to a more progressive income tax structure.

    Redistributive income taxation under outsourcing and foreign direct investment2011In: Economics Letters, ISSN 0165-1765, E-ISSN 1873-7374, Vol. 110, p. 86-89Article in journal (Refereed)
    Abstract [en]

    This paper deals with optimal income taxation under international outsourcing and FDI. We show how the joint effect of outsourcing and FDI on the optimal marginal income tax rates depends on whether FDI is horizontal or vertical.

    Welfare equivalent NNP and habit formation2008In: Economics Letters, ISSN 0165-1765, E-ISSN 1873-7374, Vol. 98, no 1, p. 84-88sArticle in journal (Refereed)
    Abstract [en]

    This note concerns the importance of habit formation for social accounting. With internal habit formation, earlier procedures for welfare measurement in the first best apply with minor modifications. This result strengthens the idea behind using the comprehensive net national product as a welfare indicator. If, on the other hand, part of the habit formation is exogenous to each consumer, the exact welfare measure will also reflect the associated external effect.

    Decentralized fiscal federalism revisited: Optimal income taxation and public goods under horizontal leadership2012In: Economics Letters, ISSN 0165-1765, E-ISSN 1873-7374, Vol. 117, no 1, p. 223-226Article in journal (Refereed)
    Abstract [en]

    This paper concerns optimal taxation and public goods in an economic federation with decentralized leadership, where one lower level government is the first mover also in the horizontal dimension. Under plausible assumptions, horizontal leadership reinforces the incentives created by decentralized leadership.

    Abstract [en]

    This paper concerns the policy implications of a potential self-control problem underlying the consumption of unhealthy food. Our results show that subsidies on wealth and healthcapital can be used to implement a socially optimal resource allocation.

    Omitted variables in a weibull regression model1984In: Economics Letters, ISSN 0165-1765, E-ISSN 1873-7374, Vol. 16, no 3-4, p. 279-283Article in journal (Refereed)
    Abstract [en]

    Asymptotic biases of maximum likelihood and least squares estimators in a Weibull model, subject to omitted variables, are given. The results are contrasted to those of a small sample Monte Carlo experiment.

    Small sample properties in a heterogenous Weibull model1986In: Economics Letters, ISSN 0165-1765, E-ISSN 1873-7374, Vol. 21, no 1, p. 17-20Article in journal (Refereed)
    Abstract [en]

    Neglected heterogeneity implies bias for estimators in, e.g., the Weibull duration model. In a Monte Carlo experiment the proper maximum likelihood estimator is better than a new least squares estimator. The likelihood estimator neglecting heterogeneity is inferior.

    Estimating the perceived tax scale within a labor supply model1996In: Economics Letters, ISSN 0165-1765, E-ISSN 1873-7374, Vol. 52, no 1, p. 75-79Article in journal (Refereed)
    Abstract [en]

    The Swedish marginal tax scale is too complex to be known in detail by individuals. This paper indicates that perceived tax scales can be estimated jointly with a labor supply equation. The differences between the true and estimated tax scales are found to be small.

    Proxy variables and nonparametric identification of causal effects2017In: Economics Letters, ISSN 0165-1765, E-ISSN 1873-7374, Vol. 150, p. 152-154Article in journal (Refereed)
    Abstract [en]

    Proxy variables are often used in linear regression models with the aim of removing potential confounding bias. In this paper we formalise proxy variables within the potential outcomes framework, giving conditions under which it can be shown that causal effects are nonparametrically identified. We characterise two types of proxy variables and give concrete examples where the proxy conditions introduced may hold by design.

    Physicians prescribing originals causes welfare losses2018In: Economics Letters, ISSN 0165-1765, E-ISSN 1873-7374, Vol. 170, p. 143-146Article in journal (Refereed)
    Abstract [en]

    We analyze 319,000 choices of medically equivalent drugs at Swedish pharmacies. The results show that patients dislike substitutions for the prescribed product and that this effect is larger when the prescribed product is an original. At the same time, patients have strong preferences to buy the cheapest generic product. This implies that patients in most cases buy the cheapest generic product and experience welfare losses when the physician has prescribed another product.

    Stock exchange mergers and return co-movement: A flexible dynamic component correlations model2013In: Economics Letters, ISSN 0165-1765, E-ISSN 1873-7374, Vol. 121, no 3, p. 511-515Article in journal (Refereed)
    Abstract [en]

    The creation of a common cross-border stock trading platform is found, by use of a Flexible Dynamic Component Correlations (FDCC) model, to have increased long-run trends in conditional correlations between foreign and domestic stock market returns.

    Earned wealth, engaged bidders? Evidence from a second-price auction.2009In: Economics Letters, ISSN 0165-1765, E-ISSN 1873-7374, Vol. 105, no 1, p. 36-38Article in journal (Refereed)
    Abstract [en]

    This paper considers whether earned wealth affects bidding behavior in an induced-value second-price auction. We find people bid more sincerely in the auction with earned wealth given monetary incentives; earned wealth did not induce sincere bidding in hypothetical auctions.

    A flexible specification of adjustment costs in dynamic factor demand models2001In: Economics Letters, ISSN 0165-1765, E-ISSN 1873-7374, Vol. 72, no 2, p. 144-150Article in journal (Refereed)
    Abstract [en]

    This paper proposes a flexible form of adjustment cost function. An empirical illustration shows that the flexible form can detect both convex and non-convex adjustment costs. Furthermore, the flexible form permits testing for the experience effect on adjustment cost.

    Dynamic cost-benefit analysis of large projects: the role of capital cost2010In: Economics Letters, ISSN 0165-1765, E-ISSN 1873-7374, Vol. 109, no 2, p. 128-130Article in journal (Refereed)
    Abstract [en]

    This paper derives a dynamic cost–benefit rule for evaluating large projects. We show that, in addition to the conventional income and consumer surplus measures, the rule also entails an extra term involving capital cost changes.

    Comprehensive NNP-social welfare, and the rate of return2006In: Economics Letters, ISSN 0165-1765, E-ISSN 1873-7374, ISSN 0165-1765, Vol. 90, no 2, p. 254-259Article in journal (Refereed)
    Abstract [en]

    We show that growth in NNP measured in constant prices indicates welfare improvement, provided that an observable rate of return measure is positive. This is an alternative welfare interpretation of growth in comprehensive NNP compared with that of Asheim and Weitzman [Asheim, B.G., Weitzman, M.L., 2001. Does NNP growth indicate welfare improvement? Economic Letters 73, 233–239] which is based on a Divisia consumer price index.
