A Socio‐Psychological Perspective on Team Ambidexterity: The Contingency Role of Supportive Leadership Behaviours

In addressing the notion of team ambidexterity, we propose that socio‐psychological factors (i.e., team cohesion and team efficacy) may help team members to resolve paradoxical challenges and to combine exploratory and exploitative learning efforts. In addition, we theorize that senior executives may play an important role in facilitating the emergence of ambidexterity at lower hierarchical levels. In doing so, we develop a multilevel contingency framework and propose that the effectiveness of teams to achieve ambidexterity is contingent upon supportive leadership behaviours at the organizational‐level. Using multilevel, multisource, and temporally separated data on 87 teams within 37 high‐tech and pharmaceutical firms, we not only reveal how team cohesion and efficacy may matter for the emergence of team ambidexterity but also show that the effectiveness of supportive leadership behaviours from senior executives varies across cohesive and efficacious teams.     

Best fit,best practice,or stuck in the middle? The impact of unit ownership on unit HR performance in franchise systems

Franchising is an important form of entrepreneurial wealth creation in many retailing and service industries. Since Human Resource Management (HRM) is a critical factor in such industries, it is important to understand how franchisees—as semi-autonomous entrepreneurs—deal with HRM in their units and how this ultimately affects performance at the unit level. However, the very few studies linking franchisee HRM behaviors to performance have not included multi-unit franchising (MUF) as a type of unit ownership. Given the ever-increasing popularity of MUF and the unique characteristics of MUFs, this represents an important knowledge gap. We aim to fill this gap by building a theoretical framework on how the type of unit ownership affects unit HR performance within franchise systems. Building on agency, resource and entrepreneurship perspectives, we propose that units owned by single-unit franchisees (SUFs) and small MUFs (i.e., franchisees with a very small number of units) adopt a ‘best fit’ system regarding HRM, whereas company-owned units (COs) and units owned by larger MUFs (i.e., franchisees with a large number of units) typically adopt a ‘best practice’ system. Each system has its own advantages and disadvantages, which results in two contrasting propositions regarding their effects on unit performance. Moreover, we expect the units owned by medium-size MUFs to have the lowest performance since they are ‘stuck in the middle’ regarding their HRM system.     

Does Board Independence Affect Audit Fees? Evidence from Recent Regulatory Reforms

To enhance board oversight, since 2002, US legislation has required listed companies to have a majority independent board. This paper uses this legislative change to examine the relation between board independence and audit fees. To provide a clean estimate of this relation, we adopt a difference-in-difference approach using a sample matched on client firm characteristics. We find that greater board independence is insignificantly associated with a change in audit fees when client firms operate in a weak information environment. When the information environment is strong, greater board independence is associated with an increase in audit fees. Our results are consistent with the nascent theory emphasizing information asymmetry and provide insight into the effectiveness of the mandated board independence in relation to audit quality.     

Expenditure function estimates of the efficiency and distributive impact of indirect taxes in the United Kingdom

This paper uses the expenditure function to consider the efficiency and distributional impact of indirect taxes in the United Kingdom. Estimates of the parameters of the Linear Expenditure System of demand equations are employed to measure the compensating variation and equivalent variation costs of taxes on households in different income groups. In addition, distributional weights are used to consider the overall impact of different taxes and tax changes on social welfare. Finally we consider other types of demand system estimates which might be used in this kind of exercise.     

Directors'' remuneration in the theory of the firm: Specification and testing of the null hypothesis

One basis for the managerial theories has been the strong correlation between firm size and executive remuneration. This may, however, simply reflect variations in managerial quality across firms. We also show that the absence of a correlation between profitability and remuneration is not evidence in favour of the managerial theories. In this paper we follow the rewards to individual U.K. managers over time, thereby controlling for quality variation. We conclude that growth is highly rewarded and involvement in mergers and takeovers attracts an extra premium. This may explain the continued popularity of mergers despite knowledge of their general unprofitability.     

Do Australian Trade Policies Discriminate Against Less Developed Countries?*

The view that Australian protection discriminates against the less developed countries (LDCs) is examined in this paper. It distinguishes between direct discrimination through tariff preferences and indirect discrimination through inter-commodity differences in rates of protection. The second mechanism proves to be more important. While Australian protection did not discriminate against the LDCs in 1968–49, by 1977–78 it did. This reflects changes in the commodity composition of Australia's imports from the LDC_S.     

PROBLEMS IN THE COMPILATION OF INPUT-OUTPUT TABLES IN THE NETHERLANDS

This article deals with some aspects of the compilation of input-output tables (I.O. tables). A global view is given of the way in which I.O. tables are compiled in The Netherlands. It is indicated that in The Netherlands a number of developments are in progress that have led to an extension of the uses that are made of I.O. tables. The changing demands on I.O. tables that result from these developments can be met in future to an important degree. This has been made possible by extending and improving basic statistics and by increasing the uses made of automation facilities. Some problems remain, however, and one of these problems takes a central place in this article. This is the problem of accuracy and continuity: how can yearly I.O. tables be compiled that combine accuracy with consistency over time. Accuracy means here that the tables should be as complete as possible and in optimal accordance with all available information. Consistency over time means that estimates of details of I.O. tables compared with the same estimates for previous years reflect real economic developments. It is obvious that those two demands may conflict, particularly for years in which new information becomes available. It then must be decided whether accuracy or consistency in time deserves priority. What problems result from this decision and what are the consequences for the yearly I.O. tables? The problems arising from the conflicting demands of accuracy and continuity apply to the Netherlands in the last few years. This led to a revision of I.O. tables and national accounts for 1977. This revision resulted in an increase of estimated national income of more than 6 percent. For some components the adjustments have been much larger; this is particularly true for the services sector. More information on the 1977 revision is given in an annex.     

A MICROCONSISTENT EQUILIBRIUM DATA SET FOR CANADA FOR USE IN TAX POLICY ANALYSIS

In this paper we describe a micro consistent data set for Canada for 1972, assembled with general equilibrium tax policy analysis in mind. We stress the methodology used and in a number of tables report its main features.
In the data set the separate detail contained in input-output transactions tables, national accounts, household income and expenditure data, taxation statistics, foreign trade statistics, flow of funds and other sources is adjusted for mutual consistency. The final result is a micro consistent data set in which demands equal supplies for all products, zero profit conditions hold for industries and all agents' demands satisfy their budget constraints.
The motivation for data assembly is the currently widely used practice of calibrating "empirical" general equilibrium models so as to exactly reproduce a base year data observation as an equilibrium model solution. This procedure enables empirically based models to evaluate counterfactual equilibria in a way which corresponds to comparative static analysis in theoretical literature.
More detail on the data set is available on request in appendices deleted from the published version of this paper due to space constraints.     

Existence of voting-market equilibria

We show the existence of an equilibrium in a model where private goods are allocated by markets and the public good (bad) is allocated by majority rule voting.     

Von Neumann-Morgenstern solution social choice functions: An impossibility theorem

Recent literature has made significant progress in characterizing those social choice functions that can arise, or be “implemented,” as the equilibria of an underlying noncooperative game. This paper studies the implementability of social choice functions via cooperative games. Specifically, we show that if a social choice function arises, in each environment, as a Von Neumann-Morgenstern solution of an underlying cooperative game, whose dominance structure is monotonic and neutral, then the social choice function is essentially oligarchic, in exactly the same sense that “core” selecting choice functions are oligarchic.
