Is the Optimal Labor Income Tax Progressive in a Unionized Economy?*

This paper concerns optimal nonlinear labor income taxation in an economy with union wage setting and endogenous hours of work. The purpose is to study the determinants of tax progression. We show that the optimal degree of progression of the labor income tax depends on the extent to which the government can influence the wage rate via tax policy as well as on its ability to redistribute income across individuals. In addition, the argument for progressive labor income taxation depends on whether hours of work are chosen by the employed themselves or the union.     

The Manipulability of Matching Rules via Segmentation

Our matching problems feature agents with endowments facing certain division rules. At any matching, the endowments of agents are reallocated between the matched pairs according to some given division rule, and this opens doors to an iterated matching problem and rematching, and to manipulation of some matching rules via segmentation. In this form of manipulation a coalition breaks off from the rest, matches within itself and rejoins the complementary coalition for a rematching at the new endowment profile. Under certain division rules this may benefit the coalition who breaks off without hurting the complementary coalition. Furthermore, both may benefit by first matching internally and then rejoining for a new match.     

Only the lonely? The influence of the spouse on the transition to self-employment

Previous research showed that married individuals are overrepresented among the self-employed. Few studies proposed skill-spillover between the spouses within the marriage as an explanation. This paper deviates from the previous research by exploring different relationship contexts (e.g., cohabitation, being married or divorced, a widow(er) or single) and the role of partner influences under these contexts. It argues that the interaction between gender and relationship status implies variation in not only resources but also constraints, and hence sorts individuals into two different types of self-employment: entrepreneurial self-employment (i.e., incorporated business) and unincorporated self-employment. Using “Panel Study of Income Dynamics (PSID) 1965–2005” data, results of the competing risk models show that marital status contributes to both types of self-employment transitions, especially for men, but also for women. Cohabitation is a less supportive context for entrepreneurship and a partner’s self-employment experience increases only women’s likelihood of entering into entrepreneurship. These results suggest that skill-spillover between partners might be context dependent and only in one direction (from men to women).     

Instrument rules in monetary policy under heterogeneity in currency trade

We embed different instrument rules into Galí and Monacelli’s new Keynesian model for a small open economy that is augmented with technical trading in currency trade to examine the prerequisites for monetary policy. Specifically, conditions for a determinate and least squares learnable REE are in focus. When a contemporaneous data specification of the rule is used in policy-making, the degree of trend following in currency trade does not affect these conditions, except in case of an extensive use of trend following, whereas a forward expectations specification makes it less likely to have a determinate and learnable REE when the degree of trend following is increasing. We allow for interest rate inertia in the analysis.     

Developing Pharmacy Services: a Customer-driven Interaction and Counselling Approach

In recent years, many traditional businesses have been facing demands to extend their core product and incorporate a substantial service element. The transition from traditional business to service enterprise cannot be accomplished without considerable attention being given to ways of fulfilling cus- tomer needs. This study looks at the pharmacy business and asks what kind of pharmacy services different customer groups want, how these groups can be distinguished and what the implications are for pharmacy service development. It identifies four customer groups - the contented, phormacist- dependent customer, the independent customer, the infor- mation seeker and the discontented customer -and concludes that the future success of the pharmacies depends on how much they take the desires of these groups into consideration in developing their services.     

Speculative attacks and currency crises: The Mexican experience

By using data from the Mexican economy, this paper estimates a speculative attack model of currency crises in order to identify the role of macroeconomic fundamentals and early warning signals of a potential currency crisis. A deterioration in fundamentals appears to generate high one-step-ahead probabilities for the observed regime changes during the sample period 1982–1994. Particularly, foreign reserve losses, expansionary output, monetary and fiscal policies, an increase in inflation differentials and the share of short-term foreign currency-indexed debt, and an appreciation of the real exchange rate appear to have contributed to the speculative pressures and the associated regime changes.     

Firms,public good provision and institutional uncertainty: Evidence from Russia

Enterprises in post-socialist and transition economies often participate in providing infrastructure and social services to the surrounding community which in the Russian legal setting should be local authorities’ responsibility. We propose that this bundling of social and infrastructure goods provision with firm's core operations is a fully rational choice in an uncertain institutional environment. A unique survey data suggest that this manifests itself through more reliable infrastructure, stronger employee attachment to the firm and, most interestingly, through better relations with the authorities. Relationship with authorities is a two-way game where the firm gains from the arrangement but on the other faces sanctions if it decided to depart from it. Firm's participation in the arrangement is clearly enhanced by inherited fixed capital assets from the Soviet era.     

Effects of commitment on intentional loyalty at the person-to-person and person-to-firm levels

This study explores how customers’ affective commitment and calculative commitment to the personal adviser and bank, respectively, affect their intentional loyalty to the personal adviser and bank. Data were collected using a web survey of mass affluent customers of a major Swedish bank. Responses were measured and analysed using factor, correlation, and regression analyses. The results reveal that the person-to-person and person-to-firm loyalty categories are influenced by affective and calculative commitment to the personal advisor and by affective commitment to the bank, but not by calculative commitment to the bank. Moreover, there is a strong relationship between customer loyalty to the personal adviser and to the bank. It can be concluded that affective commitment has a stronger overall impact on customer loyalty than does calculative commitment, indicating the importance of creating affective ties with customers, and that personal advisers are central to bank – customer relationships. The importance of financial issues to mass affluent customers implies that both affective commitment and calculative commitment to the personal adviser are important in building customer loyalty to a bank or brand.
