The relationship between private investors and small firms: an agency theory approach

Many small firms in Sweden are characterized by a lack of equity capital. For several years measures to increase the equity capital have been discussed. In this discussion the private investors' market has received virtually no attention. This study presents some preliminary results of the private investors in Sweden.

The research in small firms financing is characterized by a lack of theoretical framework. One basic assumption in the study is that agency theory can provide an essential framework to explain the interaction between the private investor and entrepreneur. Twenty-five hypotheses generated from agency theory are formulated and tested on 62 small unlisted firms in Sweden. Multiple regression analysis is used for the causal analyses.

The empirical results in the study show inter alia that the geographic distance and the private investor's knowledge about the portfolio firm's transformation process seem to be the most influential factors for determining the private investor's involvement in the portfolio firms. It is also interesting to notice that none of the variables, frequency of contacts and the private investor's operational work in the portfolio firm affect the performance of the firm. Contrary to conventional wisdom, private investors do not add value to their portfolio firms through their interaction with the entrepreneurs.

The theoretical conclusion is that agency theory does not provide any satisfactory framework to explain the private investor - entrepreneur relationship. Some of the basic assumptions in agency theory seem to be invalid. A model for the relationship between private investors and entrepreneurs is developed in which four interaction strategies are identified. The model gives implications on two levels: the portfolio level and the individual case level.     

Dividends,research and development expenditures,and the value relevance of book value for UK loss-making firms

We extend prior research on the value relevance of accounting information for loss-making firms by allowing the coefficient of book value to vary across three distinct set of loss-making firm observations in our valuation model. Our key findings are, first, that book value is a less important determinant of equity value for either high R&D-intensive firms or dividend-paying firms, relative to firms with low R&D-intensity and zero dividends. Prior literature suggests that book value is a strong indicator of firm value for loss-making firms. This reasoning stems from book value's role as: (i) a proxy for the value of the possibility of abandoning or adapting the firms' net assets; and/or (ii) a proxy for expected future normal earnings. Our work suggests that this prior literature does not fully capture the valuation role of book value for loss-making firms. Second, we also find that dividends are value relevant, but generally only when the valuation role of book value is contextualised by allowing its coefficient to vary across high R&D-intensive firms, and dividend-paying, loss-making firms.     

Market Orientation,Competitive Strategy and Firm Performance

Abstract

In this paper, we investigate the mediating effects of a firm's competitive strategy in the market orientation-performance relationship. Based on a sample of 371 manufacturing firms in China, evidence was found that the three dimensions of market orientation exert different effects on competitive strategy and performance. Among them, customer orientation has the strongest association with competitive strategy and market performance. This lends credence to a componentwise approach on the study of the relationship between market orientation and performance. The results of structural equation analyses indicate that the mediating effect of competitive strategy is mainly revealed in innovation strategy, the most vital factor in creating superior value for the company in the emerging market. Limitations of this study and implications for future studies are discussed.

Internationalising Professional Skill Development

ABSTRACT

Internationalisation of education, and more specifically tertiary education, all over the world has contributed to a significant overhaul in student composition. Parallel to this runs the need for graduates to leave university with a range of professional skills. In response to this, universities actively encourage the development of such skills in their programs by integrating the teaching and assessing of professional skills into academic programs. This paper reports on the efficacy of a professional skills program and its support structures as used in the Bachelor of Commerce degree program of a university. The paper outlines how the skills were taught and assessed in the International Management 375 unit and presents data on the changes in students' perceptions of their skill levels. The interpretation of the data is further differentiated on the base of gender, language and country of origin.     

Infinitesimal Firms and Increasing Cost Industries

This article presents a rigorous version of the basic model of an increasing-cost competitive industry found in many textbooks. In the model, firms are infinitesimal, which justifies price-taking behavior and a continuous industry supply curve. The industry supply curve slopes upward because of dispersion in the efficiency of firms. In this framework, the authors emphasize the role of the marginal firm. This role is not clearly emphasized in many textbook presentations of the increasing cost industry.     

Professional forecasters and real-time forecasting with a DSGE model

This paper analyses the real-time forecasting performance of the New Keynesian DSGE model of Galí, Smets and Wouters (2012), estimated on euro area data. It investigates the extent to which the inclusion of forecasts of inflation, GDP growth and unemployment by professional forecasters improve the forecasting performance. We consider two approaches for conditioning on such information. Under the “noise” approach, the mean professional forecasts are assumed to be noisy indicators of the rational expectations forecasts implied by the DSGE model. Under the “news” approach, it is assumed that the forecasts reveal the presence of expected future structural shocks in line with those estimated in the past. The forecasts of the DSGE model are compared with those from a Bayesian VAR model, an AR(1) model, a sample mean and a random walk.     

Audit Market Response to PCAOB Censures of US Big 4 Firms

Abstract

Subsequent to the first-ever Public Company Accounting Oversight Board (PCAOB) censure of a US Big 4 firm (Deloitte) in December 2007, there were two other PCAOB US Big 4 firm censures as of 2016 year-end. We examine whether these two post-2007 PCAOB censures of US Big 4 firms conveyed new information to the audit market. For both censures, we find little or no evidence of any change in the factual audit quality of the censured firm over a three-year window surrounding the censure. Our findings suggest that the quality control deficiencies (identified during inspection of specific audit engagements) that triggered the PCAOB censure were isolated occurrences rather than systemic to the firm at large, i.e., the censures do not imply an impairment in the US Big 4 firm's overall factual audit quality. We also find that the negative response of investors and audit committees documented in prior research for the 2007 Deloitte censure disappeared for the later US Big 4 firm censures. Given that the PCAOB inspects (and can censure) non-US auditors who audit US-listed foreign companies, our findings are of potential interest to regulators, investors and audit committees outside the US.
