Implicit social preferences in the Norwegian system of indirect taxation

The revelation of implicit social preferences is a fresh field of econometrics. In this paper the theoretical setting is a model of optimal indirect taxation. A parametric preference function is specified, which makes it possible to separate and quantify three different effects. First, it provides a condensed quantitative measure of the degree of income inequality aversion. Second, a set of parameters evaluate external social costs induced by the consumption of certain commodities. Finally, the function allows estimation of implicit equivalent income scales. The authors consider the results as a source of information about an important part of Norwegian tax policy.     

Two comments on tax evasion

A simple theoretical model of tax evasion behaviour is used to analyse whether a large fine (with small probability of detection) is a more powerful deterrent to tax evasion than a high probability of detection (with a small penalty). The effect of a higher tax rate on the amount of tax escaping the tax collector is also examined.     

Visitors’ acceptance of negative ecological impacts in national parks: comparing the explanatory power of psychographic scales in a Norwegian mountain setting

Even in protected areas, it is inevitable that any human use will produce some impact on natural resources. This study identifies visitors’ tolerance of potential negative ecological impacts from tourism activities and facilities in a Norwegian national park context, based on park visitors’ expressed degree of acceptance of negative effects on particular species of wildlife (wild reindeer and raptors) and on vegetation. Attitudes were analysed using psychographic scales, reflecting respondents’ nature orientations, their specific facility desires, their preferences in a wilderness setting and their concerns about human interaction with the natural environment. Fourteen research hypotheses were tested. Findings demonstrated that the psychographic scales explained more variation in attitudes than most social background and trip characteristics. Higher levels of education among visitors were strongly associated with increased ecological concern; age and gender were not. There was generally strong ecological awareness and eco-centrism among park visitors in general, with a small proportion of wilderness purists. Better trail conditions, signposting and interpretation were sought. But park visitors were also found to possess a complex mixture of needs and drivers. The study found significant potential for strategic alliances between tourism and conservation interests, and key value issues for park governance systems.     

Public Provision of Private Goods,Self‐Selection,and Income Tax Avoidance

Redistributive taxation should benefit those with low earnings capacity rather than those who choose a lower income to obtain tax savings. Several contributions have highlighted how public provision of work complements can discourage people from lowering labor supply to diminish taxable income. We show how tax avoidance, previously neglected, can alter the conclusions regarding public provision. Tax avoidance breaks the link between labor supply and reported income. An agent reducing his reported income to escape taxes might no longer forego a publicly provided labor complement, because he can now lower his income by avoiding more rather than working less.     

Short-term asymptotics for the implied volatility skew under a stochastic volatility model with Lévy jumps

The implied volatility skew has received relatively little attention in the literature on short-term asymptotics for financial models with jumps, despite its importance in model selection and calibration. We rectify this by providing high order asymptotic expansions for the at-the-money implied volatility skew, under a rich class of stochastic volatility models with independent stable-like jumps of infinite variation. The case of a pure-jump stable-like Lévy model is also considered under the minimal possible conditions for the resulting expansion to be well defined. Unlike recent results for “near-the-money” option prices and implied volatility, the results herein aid in understanding how the implied volatility smile near expiry is affected by important features of the continuous component, such as the leverage and vol-of-vol parameters. As intermediary results, we obtain high order expansions for at-the-money digital call option prices, which furthermore allow us to infer analogous results for the delta of at-the-money options. Simulation results indicate that our asymptotic expansions give good fits for options with maturities up to one month, underpinning their relevance in practical applications, and an analysis of the implied volatility skew in recent S&P 500 options data shows it to be consistent with the infinite variation jump component of our models.     

Tourism stakeholders’ perceptions of national park management in Norway

Local tourism firms represent an important stakeholder interest in national parks. The present study examines these stakeholders’ perceptions of management processes and their assessments of the resulting management plans and operations. This research is based on qualitative interviews with representatives of tourism businesses in two different national park settings in Norway – Rondane National Park and Jotunheimen National Park. The findings illustrate that despite their general support for the national park status, the local tourism stakeholders interviewed had experienced only minor involvement in the management planning process, and had had very little influence in the final management decisions. They believed that opportunities for business operations were lacking due to excessive management restrictions, and that managers lacked competence with regard to business management and tourism development issues. In addition, they thought that management authorities should more explicitly include sustainable tourism development in their visions and goals. Based on the findings, it is assumed that there is potential for local tourism operators to take greater responsibility in planning processes and management operations. It is concluded that measures should be taken to foster durable social links and trustworthy planning partnerships between responsible managers and local tourism stakeholders in the two national parks.     

Optimal commodity taxation with duty-free shopping

International travellers are frequently offered the opportunity to purchase a certain quantity of goods duty-free. Individuals differ in their opportunities to benefit from duty-free shopping, and we focus on the implications of these differences for optimal commodity taxation within a version of the optimal tax model of Mirrlees (Review of Economic Studies, 38, 175–208, 1971). We show how duty-free alters the constraints on the use of commodity taxes to reduce the distortionary costs of income taxation or to reflect externalities. Beyond characterising optimal taxes in the duty-free regime, we discuss conditions under which allowing duty-free would increase or reduce social welfare.      

Sociocultural impacts of tourism in Scandinavia: Studies of three host communities

In one of the first comparative studies of its kind into the socioeconomic impacts of tourism in Scandinavia, three host communities, Hemsedal in Norway, Sälen in Sweden and Blokhus in Denmark, were studied. All the communities, once dominated by farming and small scale industry and now the recipients of mass tourism on varying scales, were questioned on the economic, social and cultural impacts of tourism. Negative attitudes towards tourism were found to be strongest from those engaged in more traditional occupations and to be directly related to the level of tourism development.     

The choice of excise taxes when savings and labour decisions are distorted

The framework is a simple two period life-cycle model with identical individuals who work in period 1 and are retired in period 2. Initially there are optimally chosen uniform income and commodity tax rates, which lead to distortions in both the labour/leisure choice and the consumption/savings choice. The purpose is to demonstrate in an intuitively comprehensible way how differentiating commodity taxation by slightly increasing the tax on one consumption good can mitigate existing distortions. The sufficient conditions for a welfare improvement are similar to that of Corlett and Hague plus some conditions on average and marginal consumption propensities.
