Cost efficiency and scale economies in the Turkish insurance industry

This article examines the cost efficiency and scale economies of insurance firms in the Turkish insurance industry over a 15-year period, 1990–2004. Using the stochastic cost frontier model, cost efficiency scores and scale economies were estimated for each firm in the sample. The results show that mean cost inefficiencies range between 18.3 and 36.9% of total costs and they do not tend to decrease over time. On average, small firms are more cost efficient than large firms. Economies of scale appear present and significant for any class size. The results suggest that there is a substantial difference in scale economies between small and large insurance firms.     

Are bid preferences benign? The effect of small business subsidies in highway procurement auctions

Bid preferences in procurement auctions allow firms from an identifiable group an advantage in bidding against unfavored firms. While economic efficiency is expected to fall as a result of bid preferences, government procurement costs may either increase or decrease depending on the competitive response of favored and unfavored firms. This paper uses data from California auctions for road construction contracts, where small businesses receive a 5-percent bid preference in auctions for projects using only state funds and no preferential treatment on projects using federal aid. I show that while firms' bidding behavior matches theoretical predictions, procurement costs are 3.8 percent higher on auctions using preferences. The higher procurement cost in preference auctions is attributed to reduced participation by lower cost large firms.Structural estimates of latent firm costs are then used to evaluate how efficiency and the division of surplus between firms and the government are impacted by bid preferences. Firm profits are 3.1 percent lower under bid preferences, however this is overwhelmed by the efficiency loss due to reduced large firm participation. The efficiency loss conditional on firm participation is estimated to represent around 0.1 percent of overall procurement costs. Including the adverse effect of preferences on the participation of large firms increases the estimated efficiency loss to 3.6 percent, which represents 27 cents for each additional dollar awarded to small businesses through the program. Counterfactual simulations indicate that if participation were instead inelastic to bid preferences, the 5-percent bid preference would be close to the optimal level.     

International Trade,Offshoring and Heterogeneous Firms

Recent trade models determine the equilibrium distribution of firm‐level efficiency endogenously and show that freer trade shifts the distribution towards higher average productivity because of entry and exit of firms. These models ignore the possibility that freer trade also alters the firm‐size distribution via international firm migration (offshoring); firms must, by assumption, produce in their “birth nation.” We show that when firms are allowed to switch locations, new productivity effects arise. Freer trade induces the most efficient small‐nation firms to move to the large nation. The large country gets an “extra helping” of the most efficient firms while the small nation's firm‐size distribution is truncated on both ends. This reinforces the large‐nation productivity gain while reducing or even reversing the small‐nation productivity gain. The small nation is nevertheless better off allowing firm migration.     

Firm size and types of innovation

We propose a general theory of innovation that illustrates the relative benefits of performing process versus product R&D when firm size is endogenous. A firm's size, scope, and R&D portfolio are shown to reflect the same underlying characteristic of the firm, namely manufacturing efficiency. We demonstrate that efficient firms become larger, have greater scope, and perform more of both process and product R&D. In light of decreasing returns to R&D, this implies small firms obtain more product innovations per dollar of R&D than large firms, which is consistent with evidence we present that small firms are more innovative than large firms as they obtain more patent counts and citations per dollar of R&D.     

INVENTOR PRODUCTIVITY AND FIRM SIZE: EVIDENCE FROM PANEL DATA ON INVENTORS

It has long been recognized that worker wages and productivity are higher in large firms. Moreover, economists have been interested in the efficiency of large firms in R&D enterprises. This paper uses inventor panel data to examine the relationship between inventor productivity and firm size in the pharmaceutical and semiconductor industries. In both industries, we find that inventors' productivity increases with firm size even after controlling for inventors' experience, education and other firm characteristics. We find evidence in the pharmaceutical industry that this is partly accounted for by differences in the way in which large and small firms organize R&D activities.     

Technology,Exports And Firm Efficiency In Taiwanese Manufacturing

Using firm-level data from the 1986 Census of Manufactures of Taiwan, we examine the links between technical efficiency and firm investments in technology and exports. Stochastic production frontier techniques are used to estimate the technical efficiency of firms by investments in technology as well as by export orientation. Our results indicate that accounting for firm investments in technology is critical in explaining the strong export-productivity link in the extant literature. For the group of large, high technology firms, the differences in the mean efficiencies between exporters and non-exporters are not significantly different than zero in all nine industries under study. However, for the large number of small firms that make no formal investments in technology. exporters are significantly closer to the production frontier than their counterparts that sell in the domestic market.     

Investment decisions and the soft budget constraint

This paper investigates the investment behaviour of a large panel of Hungarian firms in the period 1989–99, in order to assess the impact of institutional and regulatory changes on the efficiency of credit allocation. We find that the role of financial factors for investment decisions has changed significantly after the introduction of major financial reforms, and that firms were affected differently depending on their ownership type. Reforms have hardened the budget constraint of private domestic firms, particularly small ones, and reduced informational problems for foreign‐owned firms. State‐owned firms remained subject to a soft budget constraint. In particular, small state firms became more sensitive to financial conditions, whereas large state firms were unaffected and kept operating under a soft budget constraint.     

CONCENTRATION-PROFITS MONOPOLY VS. EFFICIENCY DEBATE: SOUTH AFRICAN EVIDENCE

Using the new official measures of concentration, this study finds a strong and highly significant correlation between concentration and industry profitability for South African manufacturing industries. This correlation is consistent with both the monopoly hypothesis of the traditional structure-conduct-performance paradigm and Demsetz's efficiency hypothesis that concentration of industry reflects the dominance of superior low-cost firms. Using the four-firm concentration ratio, this study applies Chappell and Cottle's extension of the Demsetz test to distinguish between the monopoly explanation of this correlation and the efficiency explanation. Using a conventional regression specification of the concentration-profits relationship with no control for efficiency, this study finds a statistically significant coefficient only for the industry and large size class regressions. Because small firms should do at least as well as large firms, under the price umbrella provided by large firms, this result is inconsistent with the monopoly hypothesis but consistent with the efficiency hypothesis. Specifying a variable that measures the efficiency of large plants relative to smaller plants—the cost advantage ratio—yields striking results. Similar to the results obtained by Chappell and Cottle for the United States, this study finds the efficiency variable to be highly significant in the industry and large size class regressions, while concentration becomes insignificant. Moreover, the efficiency variable is insignificant in the smaller size classes Both the statistical insignificance of concentration and the pattern of the efficiency variable coefficients suggest that including concentration in the regression specification without the efficiency variable simply highlights the effect of the efficiency variable. Coming as they do from an environment as different from the United States as the South Africa of the 1980s, these results strongly support the Demsetz efficiency hypothesis.     

The effects of economic reforms on manufacturing dualism: Evidence from India

Dualism is a pervasive feature of the manufacturing sectors of less-developed countries, with large differences in productivity between the informal and the formal sectors. Policy distortions are viewed as an important factor behind the prevalence of manufacturing dualism. We examine whether tariff reforms, industrial de-licensing and the withdrawal of reservation of products for small firms implemented since the mid-1980s have had any effects on efficiency differentials between informal and formal firms in Indian manufacturing. We find strong evidence that economic reforms have exacerbated dualism by increasing the productivity differentials between the more efficient formal firms and the less efficient informal firms.     

An analysis of cost-reduction innovation under capacity constrained inputs

This article focuses on duopoly cost-reduction innovation with the upstream input subjected to capacity constraints. By two-stage duopoly model, some interesting conclusions are achieved. Firstly, the higher efficiency firms invest the less in cost-reduction innovation and require the fewer resources under capacity constraints. Therefore, lower efficiency firms launch the lower price strategies. To our surprise, lower efficiency firms seem to be more aggressive both in innovation and in outputs. Secondly, symmetric firms’ innovation decreases with the total resources while asymmetric firms’ innovation increases with the total capacity. Finally, innovation gap decreases with both the total capacity and the degree of substitutability.     

Innovation strategy of local pharmaceutical firms in Korea: a multivariate analysis

This article examines 37 local pharamaceutical firms in Korea to identify different patterns of innovation behaviour associated with four types of firms, which are categorized by two variables: the scale of operation and technological capability. Both bivariate and multivariate analyses support the hypotheses that these four types of firms exhibit different innovation strategies and in turn the level of performance they achieved. Specifically, large firms with high technological capability diversify their efforts, investing in their own R & D and tapping foreign capabilities, and as a result exhibit the highest degree of innovativeness, while large firms with low technological capability resort primarily to the transfer of foreign technology for short-term profitability. In contrast, small firms with high technological capability rely mainly on their own R & D efforts with the assistance from local R & D institutes and enjoy the highest growth rate, whereas small firms with low technological capability imitate technologically low-grade products by hiring experienced technical personnel from other firms. There are also fragmented indications that many local firms have long evolved from small firms with low capability to large firms with high capability. Finally, managerial and theoretical implications for the innovation strategies in LDCs/NICsE are discussed.     

The relationship between efficiency and profitability with respect to the size of firms: An empirical investigation for Austria

In this paper, an attempt is made to investigate the performance of Upper-Austrian firms by size class. Considering the six derived hypotheses, why small firms have a better performance measure, some of the hypothesis with respect to profitability and labour cost efficiency are confirmed. On average, the gross residual quota (profitability measure) of small firms is higher than the one of medium-sized and large firms. However, a similar result could not be found for the productivity development. Considering the influence of the firm size on the productivity measure, there is in three out of four cases no statistically significant influence at all and in one case the opposite result is obtained indicating the larger the firm, the higher is the productivity. In the case of labour cost efficiency, the hypothesis (the smaller the firm the lower the labour cost per employee) is clearly confirmed.     

Firm size and capital structure: evidence using dynamic panel data

This article suggests that the validity of the Trade-Off Theory (TOT) and Pecking-Order Theory (POT) to explain financing decisions varies among small, medium-sized and large firms. Using dynamic panel data tests on a sample of 3439 Spanish firms over the period 1995–2003, results are partially consistent with both explanations but suggest a greater validity of pecking-order predictions for small firms. In small firms, the negative influence of profitability and the positive influence of investment opportunities and of intangible assets on firm debt predicted by the POT are heightened. However, no differences are observed between small and large firms in their speed of adjustment to the target leverage as suggested by the TOT.

The financing of small innovative firms: the Italian case

Small firms encounter difficulties in collecting external finance due to greater information problems. For small innovative firms, whose activity is more difficult to evaluate, the cost of external finance could be even higher. This paper aims to shed light on special features in financial structures of small innovative firms, compared with firms of similar size that do not innovate. The evidence shows that small innovators rely less on financial debts and more on internal financial resources; no important differences appear for large firms. This is consistent with the view that information problems mainly affect small firms. Another finding is that small innovative firms show a lower investment sensitivity to cash flow than small non-innovative firms: it is likely that the high incidence of internal financial resources allows them more flexibility in deciding their investments. No difference in investment sensitivity to cash flow, by innovative attitude, is found for large firms.     

Are small employers more cyclically sensitive? Evidence from Brazil

An important issue facing policymakers is the degree to which fluctuations in economic activity affect employment in large and small businesses across sectors and regions. This issue is particularly relevant for developing countries as it matters for the understanding of the labour market dynamics, and for devising national, sectoral, and regional labour policies that aim at dampening employment fluctuations, particularly during recessions. Using a unique monthly dataset of 27 states and eight industries from 2000:1 to 2009:7, this paper evaluates the sensitivity of businesses of different sizes to business cycle conditions in Brazil. The behaviour of the difference in employment growth rates between large and small firms is counter-cyclical and suggests that small firms are more sensitive to business cycle conditions. In addition, the SVAR impulse response analysis suggests the existence of the effect of small firms hiring cheaply from unemployment proportionally more than large ones. On the other hand, credit constraints seem to hit small firms harder and help to explain the empirical regularity that small firms are more cyclically sensitive than large ones for the Brazilian case.     

Lending technologies,banking relationships,and firms’ access to credit in Italy: the role of firm size

This paper analyses the role of lending technologies and banking relationships on firms’ credit access in Italy. Using EFIGE firm-level data, we show that the depth and strength of firm–bank relationships have heterogeneous effects on credit demand and rationing probabilities depending on the size of the borrower. Multiple banking relationships alleviate financial constraints for small firms, while borrowing from a large number of lenders hinders access to credit for large companies. Small and medium-sized enterprises with a higher share of debt with the main bank have a lower probability of being credit denied, as debt concentration contributes to overcome the opacity problems typical of the SMEs. Long-lasting relationships, by reducing information asymmetries, significantly improve access to credit for small and large firms. Conversely, we find that medium-sized enterprises are more exposed to financing constraints as relationship duration increases, due to possible lock-in effects. Finally, firms maintaining banking relationships based on transactional technologies are more likely to be credit denied, while the use of relationship lending technologies improves credit availability for both small and large enterprises.     

Small firms,bigger changes: health insurance coverage take-up rates in small firms after the ACA

Measuring the impact of the Affordable Care Act of 2010 (ACA) on employer-sponsored health insurance is essential in an era of constant changes to health policy. Using data from the Kaiser Family Foundation Employer Survey, we focus on firms with fewer than 50 employees in order to isolate the effect of the ACA on small firms. We utilize a differences‐in‐differences approach with a time fixed effect structure to provide analysis for a treatment group of small firms and a control group of large firms. After excluding firms with grandfathered plans, we find that the ACA provisions reduced health insurance coverage take-up rates in small firms by 1.96 to 2.67 percentage points (compared to large firms).     

The strategic nature of advertising in segmented markets

We develop a simple model in which firm-specific advertising has cooperative and predatory effects. Our model is set in a static market where firms are naturally segmented into two distinct submarkets: several large firms located in the core, with small firms operating as a fringe. We test the net effect of opposing market size (cooperative) and market share (predatory) effects of both fringe and core firm advertising on the advertising decisions of large firms in several US consumer industries. Empirically, fringe firm advertising leads to an increase in advertising efforts by large firms, implying strategic complementarity. On the other hand, increased advertising by core firms in an industry decreases advertising expenditures of other core firms, indicating they are strategic substitutes. Our findings imply that equilibrium levels of advertising can be greater with asymmetric, rather than symmetric, strategic interactions.     

Managing design projects in small and medium-sized firms

This paper presents initial results of a major study of the benejits and costs of investment in design i n small and medium-sized manufacturers. It shows that UK manufacturers which received a government subsidy to employ a professional design consultant for product, engineering, packaging and graphic design projects recovered their total investment i n an average of 15 months, as well as gaining other indirect benefits. However, problems i n using and managing the design consultants was a factor i n a quarter of the projects that were not implemented or produced disappointing commercial results. The problems most associated with project failure were inadequate briefing of the consultant and internal disagreements about the aims or value of the projects. Severe design management problems were most common i n firms with under 50 employees and especially affected firms with under 10 employees. Thus, while small firms often lack in-house specialist skills such as design, such firms require additional help and advice qthey are to use external resources effectively.
