MUTUAL VERSUS PROPRIETARY OWNERSHIP: AN EMPIRICAL STUDY FROM THE UK UNIT TRUST INDUSTRY WITH A COMPANY‐PRODUCT MEASURE

ABSTRACT ** : In the debate of the relative merits of differing ownership forms, most empirical studies examine either corporate performance or the product characteristics of the financial products that are available in the financial services industry. Based on the UK unit trust industry, this paper assesses which ownership form, mutual or proprietary is more efficient in managing unit trust operations and providing high return generating unit trusts. Using a combined corporate performance and product range performance metric, this study reveals no significant differences between the two ownership forms in terms of the corporate‐product performance score. The results indicate that the owner‐customer fused role in the mutual organization must be considered in the mutual versus proprietary ownership debate.     

Market Valuation and the q Theory of Investment

This study re-evaluates the role of the stock market in Japanese corporate investment decisions based on time-series data. Employing the time-series technique, we examine why the performance of Tobin's average q -type investment function is poor. We construct a series of average q and another of marginal q (a more fundamental profitability measure of investment) and investigate the relationship between the two. A cointegrating relationship is not detected between the two measures, both of which have a unit root. The divergence of average q from marginal q is not narrowed even if the imperfect competition of the output market is taken into consideration. We also examine which q measure is more relevant to Japanese corporate investment decisions by estimating separately the investment function with two measures of q as an explanatory variable. The estimation results show that entrepreneurs place more emphasis on marginal q than on average q in investment decisions.

On the Use of the Moving Average Trading Rule to Test for Weak Form Efficiency in Capital Markets

The examination for the possible existence of predictive power in the moving average trading rule has been used extensively to test the hypothesis of weak form market efficiency in capital markets. This work focuses mainly on the study of the variation of the moving average (MA) trading rule performance as a function of the length of the longer MA. Empirical analysis of daily data from NYSE and the Athens Stock Exchange reveal high variability of the performance of the MA trading rule as a function of the MA length and on some occasions the series of successive trading rule total returns is non‐stationary. These findings have direct implications in weak form market efficiency testing. Indeed, given this high variability of the performance of the MA trading rule, by just finding out that trading rules with some specific combinations of MA lengths can or cannot beat the market, as is the case in most of the published work thus far, is not enough evidence for or against the existence of weak form market efficiency. Results also show that on average in about three out of four cases trading rule signals are false, a fact that leaves a lot of space for improved trading rule performance if trading rule signals are combined with other information (e.g. filters, or volume of trade). Finally, some evidence of enhanced trading rule performance for the shorter MA lengths was found. This enhanced performance is partly attributed to the higher probability that a trading rule signal is not a whipsaw, as well as to the larger number of days out‐of‐the‐market which are associated with shorter MA lengths.     

On the optimality of the full-cost pricing

This article is aimed at defining the full-cost pricing as a leader-follower game in two-tier organizations: (i) the upstream unit fixes the production capacity and uses it as a cost driver to compute the average cost; (ii) the downstream unit operates on the market and chooses the output level on the basis of the average cost. In the Cournot oligopoly case, the full-cost pricing is compared with other pricing rules. There exists a wide range of values of the fixed cost, for which the full-cost pricing dominates any other pricing rules, in terms of gross profit.

The internal market and hospital efficiency: a stochastic distance function approach

The UK internal market was one of the first European attempts to introduce a competitive mechanism in the provision of hospital services. The assumption was that competition would have led hospitals to increase efficiency in the use of their resources. The aim of this paper is to analyse the effectiveness of this kind of reform by measuring the changes in technical efficiency of a panel of 52 acute Scottish hospitals observed from 1991/92 to 1996/97. The time period covers the whole duration of the internal market and the sample contains a different mix of both trusts and non-trusts, where the former embed the proper working of the reform. The selected model is a stochastic output distance function that includes an interaction dummy variable to allow for parameters to change over time. The results show a structural break after which hospitals change not only the way in which they provide their services, but also the kind of services they provide, favouring the quicker treatment of patients on a day basis. No significant improvement in technical efficiency is detected instead over time, nor any significant difference in efficiency between trusts and non-trusts.     

Market structure, cost of intermediation and profitability in commercial banking

The effects of market structure on the relative cost of intermediation and on profitability of banks are re-examined using market data in a unit banking environment. Unlike earlier studies, market concentration is shown to affect both measures of bank performance.

How important is employment protection legislation for Foreign Direct Investment flows in Central and Eastern European countries?1

In this article we investigate empirically the importance of labour market conditions and in particular the role of employment protection legislation as determinants of bilateral Foreign Direct Investment (FDI). We find that FDI flows are significantly higher in countries with relatively low unit labour costs. We also find that employment protection legislation does not exert a statistically significant impact on FDI flows. Our results are consistent with the interpretation that transition economies attract FDI via low production costs whereas indirect costs related to the rigidity of the labour market are less relevant.     

Is the efficient market hypothesis day-of-the-week dependent? Evidence from the banking sector

In this article, we propose a new hypothesis: that the efficient market hypothesis is day-of-the-week-dependent. We apply the test to firms belonging to the banking sector and listed on the NYSE. We find significant evidence that the efficient market hypothesis is day-of-the-week-dependent. Overall, for only 62% of firms, the unit root null hypothesis is rejected on all the five trading days. We also discover that when investors do not account for unit root properties in devising trading strategies, they obtain spurious profits.     

Efficient market hypothesis: evidence from a small open-economy

This article studies the efficient market hypothesis for the Istanbul Stock Exchange National 100 (ISEN 100) price index within the Lumsdaine and Papell two structural breaks unit root test framework. The main finding of the article shows that the ISEN 100 index is characterized by a unit root with two structural breaks, which is consistent with the efficient market hypothesis. In addition, the article applies the augmented Dickey–Fuller test, runs test and the variance-ratio test to test the weak-form efficiency of the ISEN 100. The analyses are repeated for three sub-periods delineated in view of the endogenously determined break points.     

Revisiting the Lemons Market

This article extends the standard competitive adverse selection model by allowing for qualitatively different information structures of agents on the informed side of the market. Using the stylized framework of the market for used cars, we examine the welfare properties of equilibria under the assumption that a fraction of the sellers remains uninformed about a parameter that is relevant for their own transaction. Whether market performance increases or decreases in the number of uninformed sellers is shown to depend on (1) the potential gains from trade in the market and (2) the average quality of the sellers' information structure.     

Domestic market integration and the law of one price in Brazil

This article presents the first assessment of domestic market integration in Brazil using the law of one price. The law of one price is tested using two panel unit root methodologies and a unique data set comprising price indices for 51 products across 11 metro-areas. We find that the law holds for most tradable products and, not surprisingly, nontradable products are found to be less likely to satisfy the law of one price. While these findings are consistent with evidence found for other countries, price convergence occurs very slowly in Brazil, suggesting relatively limited domestic market integration.

The wage effects of subsidized career breaks

This article studies how subsidized career breaks affect future labor market performance. The analysis uses a Swedish career break program where applications were accepted until local funds were exhausted. The rejected applicants serve as counterfactuals to derive estimates that are unaffected by selection or omitted variables. The estimated wage effect of a 10-month-long break is negative and in the order of 3 % 1–2 years after the interruption. The average applicant is estimated to have substantially lower returns to experience than the average worker. The results thus show that career breaks are costly, even for groups with low expected returns to experience, and in an environment with very compressed wages. The career breaks also induced an increase in job and task mobility whereas post-leave labor supply remained unaffected except for workers close to retirement.     

Assessing the relationship between the user-based market share and unit sales-based market share for pirated software brands in competitive markets

This article argues that in a competitive software market, in the presence of differential piracy and brand switching among the various brands within a software product category (e.g., spreadsheets), there may be no relationship between market estimates based on unit sales and the user base of a software brand (e.g., Lotus 1-2-3). Hence, marketing strategies developed for the software brand based on unit sales-based market share may be misleading. To support our argument and to quantify the relationship between unit sales-based market share and the user-based market share, we first extend a diffusion modeling approach for pirated software product categories to model the legal and illegal adoption dynamics of a software brand within a software product category. Second, to examine empirically the relationship between the user-based market share and the unit sales-based market share for a brand, we consider the diffusion of the major brands of two types of software product categories, spreadsheets and word processors, in the United Kingdom. Results indicate that in the product category of spreadsheets, for Lotus 1-2-3, the user-based market share was always less than the unit sales-based market share. On the other hand, in the product category of word processing software, the user-based market share for WordPerfect was always greater than the unit sales-based market share. Marketing implications of these results for Lotus spreadsheets, Novell WordPerfect, and the software industry are discussed.     

Ad valorem versus unit taxes: monopolistic competition, heterogeneous firms, and intra-industry reallocations

Real-world industries are composed from heterogeneous firms and substantial intra-industry reallocations take place, i.e. high productivity firms squeeze out low productivity firms. Previous tax-tool comparisons have not included these central forces of industry structure. This paper examines a general equilibrium monopolistic competition model with heterogeneous firms and intra-industry reallocations. We show that the welfare superiority of ad valorem over unit taxes under imperfect competition is not only preserved but amplified. The additional difference between the tools arises because unit taxes distort relative prices, which in turn reduces average industry productivity through reallocations (the survival and increased market share of lower productivity firms). Importantly, numerical solutions of the model reveal that the relative welfare loss from using the unit tax increases dramatically in the degree of firm heterogeneity.     

制造业产出服务化对企业绩效的作用机制 ——基于产品市场竞争的视角

制造业服务化是先进制造业与现代服务业融合的重要内涵之一,按生产关系分为投入服务化和产出服务化,产出服务化反映了制造企业向“微笑曲线”两端服务环节转型。基于产品市场竞争视角,从市场势力和产品差异化两方面探究制造业产出服务化对企业绩效的作用机制,并通过构建产出服务化测算指标,选取2008-2018年中国1987家上市公司的面板数据,运用PSM-DID方法对制造业产出服务化与企业绩效的关系进行实证检验。研究表明:(1)制造业产出服务化显著提升了企业绩效,但存在明显的地域与所有制差异。东部、中部地区以及民营制造企业产出服务化对企业绩效的提升效果较为显著,西部地区以及国有制造企业绩效的提升在考察期内并不明显,外资企业产出服务化降低了企业绩效水平;(2)制造业产出服务化可通过“市场势力”效应和“产品差异化”效应共同促进企业绩效水平的提升。但在地域与所有制上差异显著,东部、中部地区以及民营制造企业存在“市场势力”效应和“产品差异化”效应,西部地区、国有以及外资制造企业产出服务化虽能有效提高企业的市场势力和产品差异化水平,但对企业绩效水平的提升并不明显。因此,应从市场环境、社会分工、人力资本积累等方面为制造业服务化提供保障,帮助制造企业获取竞争优势。     

Equity market neutral hedge funds and the stock market: an application of score-driven copula models

In this article, we study the time-varying market neutrality of equity market neutral hedge funds. We use data from the Hedge Fund Research? Equity Market Neutral Index (HFRX EH), which represents the performance of a portfolio of individual equity market neutral hedge funds. For each day, we measure different levels of association of the Standard and Poor’s 500 (S&;P 500) index and the HFRX EH. We use non-linear dynamic conditional score models of location, scale and copula that, to the best of our knowledge, have not yet been applied in the body of literature on hedge funds. We study whether the neutrality of the HFRX EH that is evidenced in the body of literature for the period of April 1993–April 2003 also holds for the following decade, for the period of May 2003–December 2016. We estimate different average levels of association for the pre-, during- and post-periods of the US financial crisis of 2008. We find that the association of the S&;P 500 and the HFRX EH, on average, is significantly positive for the pre- and post-periods of the financial crisis, and it is significantly negative for the period during the financial crisis.     

Performance of moving average trading strategies over varying stock market conditions: the Finnish evidence

This article examines the profitability of dual moving average crossover (DMAC) trading strategies in the Finnish stock market over the period 1996 to 2012. It contributes to the existing technical analysis literature by comparing for the first time the performance of DMAC trading portfolios of individual stocks to the performance of index trading strategies based on trading on an index that consists of the same stocks. The results show that their relative performance varies over time, whereas previous studies have documented outperformance of index trading strategies over trading strategies of stock portfolios. Moreover, the great majority of 3020 DMAC strategies examined in this article outperform the corresponding buy-and-hold (B and H) strategy for both trading targets (i.e., OMX Helsinki 25 index and individual stocks included in the index) in out-of-sample tests. In addition, the decomposition of the full-sample-period performance into separate bull- and bear-period performance shows clearly that the outperformance of DMAC strategies over B and H strategy is mostly attributable to their better performance during bearish periods.
