Costs and goals of the multiproduct firm

A profit-maximizing multiproduct firm's optimum production and pricing decision rules are different if the firm's fixed resources are fully employed than if they are underutilized. If they are fully employed, the opportunity cost of using a fixed input affects the firm's pricing decisions. The way for a multiproduct firm to maximize profit is to lose money on a product if large volume and low price of that product increases sales or reduces cost for other products sufficiently. Decision rules are different for a revenue-maximizing firm than for a profit-maximizing one.     

Innovation efficiency and firm performance in a benchmarking context

This paper examines the effect of innovation efficiency on firm performance using the Greek version of the Community Innovation Survey (CIS) 2012–2014 and employs a dataset of 1,274 innovative manufacturing firms. Introducing a data envelopment analysis (DEA)-type benchmarking strategy with non-continuous knowledge inputs, the main findings suggest that innovation efficiency, although does not exert a direct impact on firm performance, moderates the relationship between the internally generated knowledge and firm performance. On the other hand, such a moderation relationship is not confirmed for the relationship between external knowledge and innovation spillovers on firm's performance. Although the impact of the embodied to innovation inputs spillovers, on firm performance, is always positive and significant, empirical results indicate that absorptive capacity exhibits diminishing returns with respect to performance.

Estimation of cost inefficiency in panel data models with firm specific and sub-company specific effects

This paper proposes a dual-level inefficiency model for analysing datasets with a sub-company structure, which permits firm inefficiency to be decomposed into two parts: a component that varies across different sub-companies within a firm (internal inefficiency); and a persistent component that applies across all sub-companies in the same firm (external inefficiency). We adapt the models developed by Kumbhakar and Hjalmarsson (J Appl Econom 10:33–47, 1995) and Kumbhakar and Heshmati (Am J Agric Econ 77:660–674, 1995), making the same distinction between persistent and residual inefficiency, but in our case across sub-companies comprising a firm, rather than over time. The proposed model is important in a regulatory context, where datasets with a sub-company structure are commonplace, and regulators are interested in identifying and eliminating both persistent and sub-company varying inefficiency. Further, as regulators often have to work with small cross-sections, the utilisation of sub-company data can be seen as an additional means of expanding cross-sectional datasets for efficiency estimation. Using an international dataset of rail infrastructure managers we demonstrate the possibility of separating firm inefficiency into its persistent and sub-company varying components. The empirical illustration highlights the danger that failure to allow for the dual-level nature of inefficiency may cause overall firm inefficiency to be underestimated.     

Is the Competitor of my Competitor also my Competitor?

This paper presents several results on multimarket competition. First, whenever a firm faces multimarket competitors that sell goods in markets to which the firm itself has no access, the firm gains a strong incentive to expand production in its own market(s). In the capacity choice model, such a firm builds larger than Cournot capacity and pushes its competitors towards other markets. Consumers always benefit from multimarket competition. In asymmetric market structures, some firms may also benefit from multimarket arrangements, but in symmetric ones, all firms are necessarily harmed by it. Second, the intensification of indirect competition is not necessarily bad for the firm. It may be the case that, the more competitors its competitors have, the higher the firm’s profit. Finally, this model also has a multiproduct interpretation which suggests that a merger of single‐product firms may be beneficial or harmful from a social welfare perspective, depending on whether the new entity will compete with several single‐product firms or another multiproduct one.     

Welfare impacts of a non-profit firm in mixed commercial markets

Utilizing a model that allows for the welfare of the commercial NPO’s stakeholders directly in terms of their consumer surplus, and indirectly in terms of NPO profits, we explore the impact of changes in the NPO’s “social concern” for consumers on market efficiency. Three separate Cournot mixed market scenarios are analyzed: competition between the NPO and a private for-profit firm, competition between the NPO and a public firm, and a market scenario that includes all three firms. We find that the technical efficiency of the NPO vis-à-vis the profit maximizer is crucial in determining whether social welfare rises or falls as the NPO places more weight on their stakeholders’ surplus. In particular, if the NPO is less technically efficient than the profit maximizer or public firm, somewhat paradoxically social welfare may fall as the NPO shows a greater social concern for consumers. In other words, a movement away from pure profit maximizing behavior by a NPO may well be detrimental in these mixed commercial markets. We also show the additional sources of revenue available to a NPO may decrease the overall welfare in these mixed market situations.     

Duration of share repurchase programs and firm performance

It is widely known that under asymmetric information, share repurchasss can be used by firms to signal firm quality. In this paper, it is shown that the duration of share repurchase programs can signal the degree of firm quality. The model predicts that the highest quality firms repurchase a fraction of their shares outstanding over a short duration, medium quality firms repurchase the same fraction over a longer duration, and low quality firms do not repurchase shares at all. An empirical investigation of firms that engage in repurchase activity supports the model.     

Some unresolved issues in the location theory of the firm

This paper presents a generalized location theory of the firm in linear space. Location outcomes are examined by utilizing a general as well as a particular transport rate structure for output and inputs and using a general concave production as well as a homogeneous production function, of the firm. The effect of a change in demand on the location is also investigated.     

Monitoring costs as a basis for the dispersion of firm ownership

This paper proposes a model of endogenous shareholder dispersion. We find ownership structure causes variance in firm value, not vice versa, and contra to Demsetz and Lehn (1985). Conditions are also identified where increases in ownership dispersion maximize firm value, contra to Shleifer and Vishny (1986). The model suggests that ownership dispersion is a dynamic phenomenon that may change with interest rates or the set of alternative uses of firm resources. The conclusion is that there is not likely to be one ‘best’ structure of firm ownership, either for an individual firm over time or for all firms at a single point in time.     

Short and long-run cost efficiency in Indian public bus companies using Data Envelopment Analysis

State Transport Undertakings (STUs) are key players in providing mass road transport in India. Given that they operate under high levels of government imposed regulatory constraints, it is imperative to study their efficiency levels. Given that capital is a relatively scarce resource in developing countries like India, it is important to obtain efficiency in the short-run where some inputs are fixed as well as over the long run, where all inputs are variable. The technique used for capturing efficiency is Data Envelopment Analysis (DEA). A key possible limitation of DEA models based on physical inputs and outputs is that for an inefficient firm, reduction in some or all inputs may be recommended. It may often be desirable for an inefficient firm to increase some less expensive inputs while reducing the use of relatively expensive ones. Hence, when market price data is available, it is advisable to use the cost variant of DEA. Also, it is possible to determine variable cost efficiency in the short run when some inputs cannot be varied. Such inputs are referred to as “quasi-fixed” inputs. In this paper, we examine short and long term efficiencies of select bus companies in India known as State Transport Undertakings (STUs) over a period of 10 years. Fleet strength has been used as the quasi-fixed input. It is possible to ascertain, through a comparison of shadow price of the quasi-fixed input, vis-à-vis its market price, as to whether the quantity of this input is sub-optimally small or large. It is found that by adopting efficiency enhancing practices, STUs can cumulatively reduce their operating costs to the extent of 9123.35 million dollars. Also the tendency to minimize costs is found to be declining over time. In the short run some STUs are found to operate with a sub optimally low fleet size.     

Technical efficiency and firm heterogeneity in stochastic frontier models: application to smallholder maize farms in Ethiopia

This study estimates the technical efficiency measures of maize producing farm households in Ethiopia using stochastic frontier (SF) panel models that take different approaches to model firm heterogeneity. The efficiency measures are found to vary depending on how the estimation model treats both unobserved and observed firm heterogeneity. Estimates from the ‘true’ random effects (TRE) models that treat firm effects as heterogeneity are found to be identical to those from pooled SF models. Those results differ from the ones generated from the basic random effects (RE) models that treat firm effects as part of overall technical inefficiency. The more flexible generalised ‘true’ random effects (GTRE) model that splits the error term into firm effects, persistent inefficiency, transient inefficiency, and a random noise component indicates the presence of higher levels of persistent inefficiency than transient inefficiency. The basic truncated-normal RE model and heteroscedastic RE model yields similar efficiency estimates. The GTRE model predict persistent efficiency measures similar to those from the basic RE and flexible RE model with environmental variables incorporated in the variance function as well as in the deterministic production frontier. These results imply that the RE and GTRE panel models provide reliable efficiency estimates for our data compared to the TRE models. All the estimated SF models generate comparable production function parameters in terms of magnitude and sign. Overall, the results underscore the importance of scrutinising stochastic frontier models for their reliability of analytical results before drawing policy inferences.

     

Productivity measurement for a distribution firm

The paper derives a consistent accounting framework for the treatment of inventories when measuring the productivity of a distribution firm. The average purchase price of an inventory item during an accounting period must be distinguished from its average selling price and these two average prices should be distinguished from the corresponding balance sheet prices. The accounting framework is implemented for a distribution firm which sold 76,000 separate items. The firm achieved a 9.6 percent per quarter total factor productivity growth rate over 6 quarters.The first author is a Professor of Economics at the University of British Columbia and a research associate of the NBER.

Drivers of firm formalization in Vietnam: an attention theory explanation

Informal enterprises are widely viewed as a mechanism to engage unemployed people in the economy and thereby alleviate poverty in developing economies. However, over-representation in an economy may lead to both economic growth and broader employment opportunities being sacrificed. This paper presents a process model to investigate three potential drivers for firms to formalize: the first from a desire to grow and develop the firm through innovation, the second from the wish to access government financial support and the third stimulated by the payment of unofficial payments or bribes. We use data from surveys of Vietnamese firms in 2005, 2007, 2009 and 2011 to investigate these drivers of formalization. Although we find support for all three of these drivers, the results differ in significance across years and firm types. We explain these differences using attention theory to show how different situations and events can make the formalization decision more likely over time.     

Employee ownership and firm performance: a meta‐analysis

Employee ownership has been an area of significant practitioner and academic interest for the past four decades. Yet, empirical results on the relationship between employee ownership and firm performance remain mixed. To aggregate findings and provide potential direction for future theoretical development, we conducted a meta‐analysis of 102 samples representing 56,984 firms. Employee ownership has a small, but positive and statistically significant relation to firm performance ( = 0.04). The effect is generally positive for studies with different sampling designs (samples assessing change in performance pre‐employee–post‐employee ownership adoption or samples on firms with employee ownership), different performance operationalisation (efficiency or growth) and firm type (publicly held or privately held). Suggesting benefits of employee ownership in a variety of contexts, we found no differences in effects on performance in publicly held versus privately held firms, stock or stock option‐based ownership plans or differences in effects across different firm sizes (i.e. number of employees). We do find that the effect of employee ownership on performance has increased in studies over time and that studies with samples from outside the USA report stronger effects than those within. We also find little to no evidence of publication bias.     

Environmental dynamism,human resource flexibility,and firm performance: analysis of a multi-level causal model

While strategic HRM scholars have conceptualized HR flexibility as an important source of sustainable superior firm performance in dynamic environments, the process through which HR flexibility creates value for the firm has not been empirically investigated. Based on a study of 98 manufacturing and 103 service firms from a wide array of industries in India, this paper attempts to illuminate the black box of causal linkages between environmental dynamism, flexibility of human assets, and firm level human-, operational-, and financial-outcomes by developing and testing a multi-level causal model. Evidence indicates that HR flexibility mediates the influence of environmental dynamism on firm performance and that irrespective of the nature of the industry and the degree of environmental turbulence, superior firm performance ensues when HR flexibility as actually possessed by the firm matches the environmental demands for such flexibility as perceived by the firm managers. The results also support the notion of HR value chain that postulates that HR system has direct impact on firm-level HR outcomes which are most proximal, and its effects on increasingly more distal operational- and financial-outcomes are mediated by HR outcomes. The findings of the study suggest that HR practices as a system have both direct and indirect (mediated by behavioral flexibility) effects on firm-level HR outcomes. Existence of significant direct effects signifies that HR practices play an important role as a structural mechanism in achieving superior firm performance.     

Corporate governance and firm efficiency: evidence from China's publicly listed firms

This paper applies a two‐stage, double bootstrapping data envelope analysis approach to investigate whether and to what extent various distinctive corporate governance practices affect productive efficiency in a sample of 461 publicly listed manufacturing firms in China between 1999 and 2002. We find that firm efficiency is negatively related to state ownership while positively related to public and employee share ownership. In addition, the relationship between ownership concentration and firm efficiency is U‐shaped, indicating the presence of tunneling activities by the largest shareholder. Among three types of controlling shareholder, state exerts the most negative impact on firm efficiency, followed by state‐owned legal entities. These results provide strong evidence that political interferences have reduced firm efficiency. It shows that the proportion of outside directors and the number of board meetings are positively associated with firm efficiency, suggesting that board of directors can be an effective internal governance mechanism. Furthermore, provincial market development, a proxy for the strength of external governance mechanism, is positively related to firm efficiency. Overall, our findings illustrate that restructuring state‐owned enterprises via improvements in corporate governance has enhanced firm efficiency, but partial privatization without transfer of ownership and control from the state to the public remains a major source of inefficiency in corporate China.

Behavior of the firm under rate-of-return regulation with two capital inputs

Traditional electric utility companies face a trade-off between building generation facilities that utilize renewable energy (RE) and non-renewable energy (non-RE). The firm's input decision to build capacity for either source depends on several constraining factors, including input prices, policies that promote or discourage RE use, and the type of regulation faced by the firm. This paper models the utility company's decision between RE and non-RE capital inputs. From the model, we derive the result that rate-of-return (ROR) regulation decreases the investment in RE capital relative to the unregulated firm. These findings suggest restructuring electricity generation markets, which removes the ROR on generating assets, can increase the relative use of RE. A second result of the model shows that the renewable portfolio standard (RPS) increases the investment in capital that requires RE as a source of electricity, as expected. This paper contributes to the literature on the substitution between renewable and non-renewable resources, by examining the policies that affect the investment in the two types of technologies. The model can also be applied to other regulated utilities, such as water or natural gas companies, with outputs that are produced from different types of capital.     

Corporate entrepreneurship and acquisitions: creating firm wealth

Acquisition is one way entrepreneurial firms have to capture the assets needed to achieve their strategic objectives. We investigate shareholder value creation of Spanish listed firms in response to announcements of acquisitions over the period 1991–2006. Similar to foreign markets, bidders earn insignificant average abnormal returns regardless of the pricing model used in the estimation procedure. When we relate these results to company and transaction characteristics our evidence suggests that the listing status of the target firm is a critical key in the strategic decision to acquire a company. This listing status effect is mainly associated with the fact that unlisted firms tend to be smaller and lesser–known firms, and thus suffer from a lack of competition in the market for corporate control. Consequently, the payment of lower premiums and the possibility of diversifying shareholders’ portfolios lead to unlisted firm acquisitions being viewed as value–orientated transactions which have major implications for managers.     

A strategic human resource perspective of firm competitive behavior

Embedded within firms are unique stores of intangible human assets that likely influence the way firms compete. We argue that the human and social capital of a firm, particularly at the upper echelon and board of director (BOD) levels, contribute to the firm's awareness of the competitive environment and its motivation and ability to undertake numerous, complex, and forceful competitive actions. We also suggest that the firm's executive compensation systems moderate the effects of these intangible human assets on firm competitive behavior. By examining how human capital, intra-firm social capital, and executive compensation influence firm competitive behavior, we advance a strategic HRM perspective of firm competitive behavior and outline several implications for future research.     

Quality investment timing by the startup and the established firm

This study investigates quality investment timing decisions of the established firm and the startup by a duopoly model, where firms can position quality early (demand uncertainty is high) or late (uncertainty has been resolved), possibly at different costs. The startup positions quality to maximize its survival probability, whereas the established firm maximizes profits. Results indicate that the startup positions quality earlier than the established firm when the demand uncertainty is high and costs do not decline sharply over time. Additionally, policy analysis shows that subsidies work better than direct funds in encouraging quality innovation of the startup.
