Segmented labour markets and the estimation of wage functions

This paper uses a stratified random sample of private sector employees to estimate wage equations for both the male labour market as a whole and six ‘segments’ of the labour market, segement which are defined with respect to the industry and size characteristics of the employing establishmen. Highly conventional results are obtained when wage equations are estimated for the male labour market as a whole, or within two segements, comprising almost half the survey population. However, one can reject conclusively the hypothesis that the same estimating equation is appropriate for modelling wage determination in all segments and if a ‘human capital’ (HK) model is, within segements, tested against more appropriate alternative hypotheses for wage determination using the Davidson and Mackinnon (1981) methodology for the testing of non-nested hypotheses, the conclusion is that one should reject the HK specification and not reject the alternative.

It is therefore argued that the disaggregation of labour market data reveals differences in the wage determination process that are not consistent with the view that labour markets are ‘dualistic’ but are consistent with the view that are segmented.     

The development of models of accounting information systems in Sweden

Traditionally, accounting has evolved as a technique. Practitioners and academics have striven to improve the technical features of accounting. Now, accounting is conceived increasingly as an organizational artefact which interacts with other organizational practices in shaping organizational reality. Taking a broad perspective of management control, this paper aims at contributing to our knowledge of accounting in this second sense and identifying some Swedish contributions to the tool-box of accounting. In reviewing the development of models of accounting information in Sweden mainly since World War II, different factors explaining the evolution of each model are identified. Analyses of these factors reveal that different groups of actors have been engaged in the development of different parts of the accounting information system (AIS). It is also noted that the introduction of models that are widely applied has delayed the emergence of new models better adapted to the current situation in business. Comparisons will be made with the development in some other countries.     

Accounting for Macroeconomic Influences on the Firm

Accounting based measures of exposure to macroeconomic shocks in exchange rates, interest rates and inflation do not capture the economic effects on the corporation of such shocks. We suggest measures that conceptually are coefficients in a multiple regression. The coefficients capture the sensitivity of a firm's real value or cash flows to unanticipated changes in each variable holding other variables constant. Information about such sensitivity coefficients would enable external stakeholders to distinguish between risk caused by firm-specific factors on the one hand and macroeconomic factors on the other. Scenario analysis is discussed as an alternative method for evaluating sensitivity coefficients. Information requirements for scenario and regression analysis are compared. Sensitivity coefficients can be used to identify a firm's functional currency or currency basket in which cash flows are independent of exchange rate changes. An example built on an actual case in Appendix demonstrates how insights can be gained from estimates of the suggested exposure measures.     

Factors affecting the price of Swedish forest land, 1965–1987

A model for the determination of the price of forest land is estimated for Sweden from 1965–1987, when (except for a few years) private non-industrial forest owners could finance their holdings at a negative real after-tax borrowing rate. It is assumed that credit has been limited by the value of mortgage security, assessed independently of the price settlement. The estimated coefficients of the regression equation are used for a calculation of the average real rate of discount of forest owners and the average value of amenities. The model also evaluates the effect of the temporary land price regulation from 1979–1987.     

A Note on Green Taxes and Double Dividends

Two highly influential articlesin the literature on green taxes and double dividends are Bovenbergand de Mooij (1994) and Goulder (1995). Goulder's primary concernis whether or not green tax reforms may increase welfare definedexclusive of environmental quality, while Bovenberg and de Mooijprimarily focus on the employment effects of such reforms. Unfortunately,Goulder misinterprets Bovenberg and de Mooij's results in takingthe sign of the uncompensated wage elasticity of labour supplyas being the decisive factor for whether or not welfare exclusiveof environmental quality rises under a green tax reform. Thiserror is pointed out and corrected in this note.     

MEDIEVAL MATCHING MARKETS

We study the regulation of brokerage in wholesale markets in premodern Central Western Europe. Examining 1,804 sets of rules from 82 cities, we find brokerage was primarily a centralized matchmaking mechanism. Brokerage was more common in towns with larger populations, better access to sea ports and trade routes, and greater political autonomy. Brokers' fee structures varied systematically: price-based fees were more common for highly heterogeneous goods, quantity-based fees for more homogeneous goods. We show theoretically that this was broadly consistent with total surplus maximization, and that brokerage was more valuable in markets with unequal numbers of buyers and sellers.
