Consumer Rationing and Cournot Outcomes: Experimental Evidence

We report the results of duopoly market experiments where firms first commit to capacities and then compete in prices. The theoretical literature pertaining to these duopoly models suggests that the way residual demand is rationed is fundamental to the character of equilibrium outcomes when capacity costs are sufficiently low. The experiments test this prediction by varying capacity cost and demand‐rationing schemes. We find that residual demand rationing does not significantly impact the capacity choices of experimental subjects, although it does affect pricing. Regardless of rationing scheme, the Cournot outcome is common with high capacity costs and rare with low capacity costs.     

Elasticities of derived demand under different objectives of the firm

Conclusions We have reconciled and generalized earlier comparisons of input demand elasticities under different objective functions of the firm. In general little can be said of the relative magnitudes of the elasticities under different objectives, since different goals usually imply different levels of production and input demand. With some simplifying assumptions about the technology we can conclude that a profit-constrained, utility-maximizing firm tends to have higher input demand elasticities than a profit-maximizing firm facing the same cost and demand functions. This tendency is reinforced by a high profit requirement, decreasing returns to scale and slowly falling demand elasticity for the output. The results may help to explain differences in the stability of employment between industries,. Scherer [1980, pp. 365–67] reports that some studies have found an inverse relation between market concentration and stability of employment, which is contrary to the expected result. One may argue that in concentrated industries the firms are likely to have organizational slack or to face an inelastic product demand curve. Hence demand for factors of production should be less elastic than in more competitive industries. We have shown, however, that deviations from profit maximization may lead to higher input demand elasticities. Since non-profit-maximizing goals are likely to be more common in concentrated industries, the observed instability of employment may be partly due to the high elasticity of derived demand. Although the type of alternative goals studied in this paper may not be realistic in practice, the analysis shows nevertheless that goals of the firm may be one factor in explaining differences in the stability of employment.     

Enterprise responses to price and output shocks in transitioning economies: The case of the Czechoslovak machine-building sector

The behavior of a sample of 161 state-owned, Czechoslovak machine-building enterprises for the period 1985–89 is examined by means of simulation techniques based on the estimated dynamic factor demand equations. The simulations of input utilization for 1990–92 indicate that the state-owned firms have been less responsive to market signals and to output changes during the transition period of 1990–92 than they were in 1985–89. This may reflect either a change in decision-making regime at the firm level or the magnitude of changes in prices and output levels that occurred in 1990–92. We also find that the output shocks were much more important for the changes in input utilization during the transition than were input price shocks. The research results reported here are part of a World Bank project on enterprise behavior in transition. The results and conclusions are solely the responsibility of the authors and in no way represent the views of the World Bank or of their respective employers.     

Self-selection and performance of R&D input of heterogeneous firms: Evidence from China's manufacturing industries

Applying the theories of heterogeneous firms and the propensity score matching difference-in-differences (PSM-DID) method to a rich dataset of Chinese manufacturing firms, this paper examines the self-selection of firm-level R&D input and estimates the net effect of R&D on productivity. The analysis shows that (1) for Chinese manufacturing firms as a whole, R&D input is influenced by firm productivity: more productive firms are more likely to invest in R&D; (2) controlling for the self-selection effect, the net output elasticities of R&D input in one year and two years after R&D input are 3.92% and 5.25%, respectively; (3) although state-owned enterprises (SOEs) are more likely than all other ownership groups to invest in R&D, the R&D input is not productive; (4) although enterprises owned by investors outside of Mainland China are the least likely to invest in R&D, the output elasticity of R&D is more significant and larger in this group than in SOEs and privately owned Chinese firms; and (5) surprisingly, the net effect of R&D is not significant in high-tech industries. Policy implications are derived from the findings.     

我国的信贷资源配置是有效的吗——基于我国上市公司投资效率视角的经验证据

作为我国企业最主要的资金来源,信贷资金在我国的国民经济中扮演着极其重要的角色,因此信贷资源配置质量的高低无疑将对我国的经济发展产生重要影响。本文以我国上市公司为研究对象,从企业投资效率的角度研究了我国的信贷资源配置效率问题。本文发现,处于过度投资状态的企业获得了更多的长期贷款;而且过度投资程度越大,它们获得的长期贷款越多。进一步的研究结果表明,企业的过度投资或投资不足的程度越大,企业价值越低。上述结果表明,我国的信贷市场是低效的,更多的信贷资源流向了处于过度投资状态的企业,而这类企业的价值较低,说明我国银行的资源配置功能较差。本文的研究丰富了信贷配给研究领域的文献,同时也为我国银行的信贷决策和我国的银行改革提供了参考依据。     

An estimate of aggregate supply response in South African agriculture

Agricultural supply has traditionally been assumed to be relatively inelastic. Time series estimates have generally supported this hypothesis. Estimates based on cross‐sectional observations have generally yielded higher elasticities. It has been argued that cross‐sectional analyses are more appropriate than time series analyses for estimating long‐run elasticities. A cross‐sectional analysis was done on South African data. Quantity supplied was shown to be a function of output/input price ratios, land quality, average rainfall and time. The long‐run supply elasticity appears to be approximately 0,92. This has important implications for agricultural price policy. Policies based on the assumption of very low supply elasticities are likely to distort markets and production.

Market Performance Implications of the Transfer Price Rule

The “transfer price rule” (TPR) defines a vertical price squeeze as an input price, output price combination set by a vertically‐integrated firm monopoly producer of an essential input that would not allow the firm's downstream unit to earn at least a normal rate of return on investment in the “as‐if” case that it had to purchase the input at the price charged independent firms. In its 2009 linkLine decision, the U.S. Supreme Court rejected the TPR for the purpose of enforcing the anti‐monopolization prohibition of Section 2 of the Sherman Act. In contrast, a vertical price squeeze, defined by a TPR‐like standard, is an abuse of a dominant position under Article 102 of the Treaty on the Functioning of the European Union. In this article, we model the impact of the TPR on market performance. We find that the TPR increases consumer surplus and net social welfare if all firms remain active in the downstream market. It sometimes induces the upstream firm to refuse to supply the downstream firm, and in such cases, consumer surplus and net social welfare are reduced. The impact of the TPR on market performance thus depends on whether or not an upstream firm can refuse to supply downstream firms on terms that would offer it at least a normal rate of return on investment.     

WOULD CHEAPER CAPITAL REPLACE LABOUR?

Left‐leaning members of the ruling alliance should be careful what they wish for. By estimating elasticities of substitution and factor demand between capital and four labour types, we find microeconomic evidence that cheaper capital would reduce demand for labour. While capital and all occupations are substitutes, many but not all occupations are themselves complements. These results allow for endogenous changes in output and apply to the vast majority of firms in our sample.     

The Effects of Norms on Investor Reactions to Derivative Use

Prior research indicates that a firm's use of derivatives to manage business risks is viewed favorably by investors. However, these studies do not consider a potentially key factor in this setting—namely, the typical behavior (or norms) regarding derivatives by other firms in the industry or the firm itself. In this paper, we report the results of multiple experiments that test whether norms are influential in affecting investors’ evaluations of firms’ derivatives choices. Our results show that the generally favorable reactions to derivative use actually reverse and become unfavorable when firms’ derivative decisions are inconsistent with industry or firm norms. Somewhat surprisingly, though, we find that industry and firm norms are not viewed similarly by investors. These results expand our understanding of how investors respond to firm's derivative use decisions and demonstrate the role of norms as factors that influence investors’ judgments in financial reporting settings. Our results have implications for firm managers making decisions about derivative use.

Intra-industry adjustment and the correction of an externality

Conclusion The purpose of this paper is to apply some of the existing microeconomic theory literature on intra-industry adjustment resulting from factor price changes to the use of corrective taxes on externalities. The optimal tax to correct the effects of an externality is one placed directly on the external damage. Such a tax is sometimes not practically feasible, in which case either the inputs or output of firms in the externality-producing industry must be taxed as a proxy for the external damage.When the tax is placed on the input associated with the externality, the tax will only produce the optimal result if all firms produce an equal external damage which is proportional to the amount of the input which is used. If the amount of the externality produced by different firms is different, then an input tax will not satisfy the marginal conditions for optimality; and in some cases, the external damage may actually increase as a result of the input tax. An output tax, on the other hand, will never cause the external damage to increase, but will not in general satisfy the marginal conditions for optimality.When the amount of external damage caused by each firm in an industry is difficult to monitor, input or output taxes are two possible policy alternatives for controlling the externality. This paper has demonstrated that there are a number of problems associated with calculating the optimal input or output tax, and that a tax that is correct under restricted assumptions may actually aggravate the problem when examined in a more general environment. This analysis may explain why policy makers favor direct controls to reduce externalities, rather than taking the economist's frequent advice of using corrective taxes to price the externality.We are indebted to Charles Maurice for helpful comments on an earlier version of this paper.     

Economic policy uncertainty and firms' investment and financing decisions in China

This paper designs a quasi-natural experiment for the identification of causal relationships between economic policy uncertainty and firms' investment-financing decisions using China's supply-side structural reform in 2015. We construct measures of asset reversibility across industries using China's national input–output flow table and match them with nonfinancial firms listed in China's A-share stock market from 2013 to 2017. We then use the difference-in-difference estimation strategy to investigate two-dimensional variations in periods (i.e., before and after 2015) and asset reversibility (i.e., high- and low-reversibility industries). The empirical results show that economic policy uncertainty significantly impedes real investment and reduces net debt issuance for private firms, whereas no such effects exist in state-owned firms. Interestingly, however, economic policy uncertainty has no significant impact on firms' cash-holding decisions.     

Factors Driving Quality Standard Compliance in the Polish Dairy Sector

We construct a model to identify determinants of the diffusion rate of quality standards in a food chain. We argue that adoption decisions in the food chain are determined by farmers’ and processors’ economic considerations. Factors such as pricing behaviour, compliance costs and market structure are identified and discussed in the paper. The findings are used to test an econometric model utilizing data on Polish milk processing firms gathered between 2000 and 2002. The results indicate that input and output prices have a significant influence on the diffusion rate of standards; the dominance of large-scale holdings in the relevant procurement market significantly increases diffusion as well. Compared to their competitors, small cooperatives were found to face more significant problems in procuring high quality raw materials.      

Human Capital Development and Its Influence on FDI Withdrawal: An Empirical Analysis

This paper examines the causal effect of human capital expansion on the exit of foreign-owned firms using the difference-in-differences method together with a quasi-natural experiment involving the expansion of higher education in China in 1999. The expansion of human capital reduces the probability of the exit of foreign-owned firms significantly. This conclusion remains robust under a series of tests, including changing the sample range, adjusting the identification method, and considering the trade liberalization. Analysis of the mechanism indicates that human capital expansion reduces the exit probability of foreign-owned firms by stimulating innovation, improving production efficiency, and optimizing the quality of input and output goods. Industries with higher asset specificity are also more likely to restrain the exit of foreign-owned firms through human capital expansion. Overall, the findings of this study provide a good insight into the exit behavior of FDI in China from the perspective of human capital.     

Multi-product firms,product mix changes and upgrading: Evidence from China's state-owned forest areas

Product selection matters for a firm's productivity and long-run growth. Recent theoretical and empirical studies indicate that an important margin of adjustment to policy reforms is the reallocation of output within firms through changes in product mix decisions. This paper examines the frequency, pervasiveness and determinants of product-switching and upgrading activities in firms located in China's state-owned forest areas during a period of gradual institutional and managerial reforms (2004–2008). We find that changes to the product mix are pervasive and characterized by adding or churning products rather than only shedding products. Moreover, changes in firms’ product mix have made a significant contribution to the aggregate output growth during our sample period. We also find that firms with different characteristics, human capital and market conditions differ in their propensity to diversify and upgrade product mix.     

Input–Output and General Equilibrium Models for Hull and Humber Region in England

This paper shows how one can construct an input output table for four Humber sub regions in England with information on levels and share of employment and output provided by the Humber Forum using coefficients from the national input–output table of UK. It then illustrates how these can be applied to construct multisectoral general equilibrium models specific to Hull, East Riding, North Lincolnshire and North East Lincolnshire regions situated in two sides of Humber estuary and a regional model that takes these four inter-dependent economies constituting the Humber economy. A dynamic model is constructed for Hull to assess the prospects in next hundred years based on micro consistent dataset in which households and firms are assumed to have perfect foresight in making their consumption and production decisions. These models are then applied to evaluate impacts of tax policies that can distort relative prices of commodities and factors of production and thus can distort the efficient allocation of scarce economic resources and on welfare of households in the Humber region. To my knowledge this is the first study of this type for this region.

Competition,asset build up and export incentives: The role of imperfect credit market

This paper studies the export incentive of credit rationed, competitive and homogenous firms through asset build up highlighting the generic trade-off between competition and asset value in an imperfect credit market where poor and rich firms have different levels of assets. It is a contribution to the issues related to finance and trade in developing countries as raised first in Jones and Marjit (2001, AER). Our theoretical and empirical results indicate that although firms in more competitive industries are likely to be exporters, history of greater local competition before the entry of firms into export market i.e. under autarky, hurts export incentive by limiting cash flows and asset build up. In our set up more intense local competition hence lower price is an advantage to access global markets, but associated low profits and hence lower assets acts a detriment.     

Prices and production: agricultural supply response in fourteenth‐century England

This article challenges the growing consensus in the literature that medieval manorial managers were price responsive in their production decisions. Using prices of and acreages planted with wheat, barley, and oats on manors held by the bishop of Winchester from 1325 to 1370, price elasticities of supply are estimated for each grain in aggregate and on each particular manor. Aggregate price elasticities of supply for wheat, barley, and oats were rarely statistically significant and when significant were very low compared with elasticities estimated for developing and developed countries in the nineteenth and twentieth centuries. The low levels of agricultural supply response in fourteenth‐century England suggest that commercialization was not as dominant in the medieval economy as has been argued. Thus, structural changes in the economy, such as the leasing of demesnes, the growth of wage labour, and the end of villeinage, may have been more important than price fluctuations in driving long‐run economic change after the Black Death. Likewise, a shift from low price responsiveness to higher price responsiveness could have been an important part of the capitalist transformation of agriculture in the early modern period.
