Strategic Incentives in Teams: Implications of Returns to Scale

This article demonstrates the critical relationship between the characteristics of the production function and the strategic incentives in a team. Equilibrium effort increases in team size when substitutability is low relative to returns to scale. Effort levels are actually strategic complements when returns to scale exceed the substitutability of members' effort. Moreover, even with equal shares the well‐known problem is determined by returns to scale and becomes worse as returns increase. While a target scheme can support the optimal output level as an equilibrium, it does not completely deter free riding. A team member will accommodate shirking by increasing their own effort within a remarkably large “accommodation zone” where the additional effort cost is less than the bonus. This accommodation of shirking by others exists for different returns to scale and even for very low levels of substitutability.     

Competing with Costco and Sam's Club: Warehouse Club Entry and Grocery Prices

Prior research shows that grocery stores reduce prices to compete with Walmart Supercenters. This study finds evidence that the competitive effects of two other big‐box retailers—Costco and Walmart‐owned Sam's Club—are quite different. Using city‐level panel grocery price data matched with a unique data set on Walmart and warehouse club locations, we find that Costco entry is associated with higher grocery prices at incumbent retailers and that the effect is strongest in cities with small populations and high grocery store densities. This is consistent with incumbents competing with Costco along nonprice dimensions, such as product quality or quality of the shopping experience. We find no evidence that Sam's Club entry affects grocery stores' prices, consistent with Sam's Club's focus on small businesses instead of consumers.     

An Equilibrium Selection Theory of Monopolization

We develop a duopoly model in which firms compete for the market (e.g., investing in process innovation or product development) as well as in the market (e.g., setting quantities or prices). Competition for the market generates multiple equilibria that differ in the firms’ investment levels, relative size, and profitability. We show that monopolization that affects competition in the market can act as an equilibrium selection device in competition for the market. In particular, it eliminates equilibria that are undesirable for the monopolizing firm, while not generating new equilibria. This result complicates the task of determining whether a firm's dominance in a given market is the result of fair competition or unlawful monopolization. We discuss a number of implications for antitrust policy and litigation, and illustrate these by means of two well‐known antitrust cases.     

Production Costs,Scale Economies,and Technical Change in U.S. Textile and Apparel Industries

The elimination of quotas in textiles and apparel poses new threats from import competition. To survive, the sectors need to find least-cost methods of production. The production–cost structure of the U.S. textile and apparel industries is examined using a dual cost framework. A translog cost function is used to measure substitution elasticities between inputs, scale economies, and the nature of technical change. The scope for factor substitution in textiles remains limited with all substitution elasticities being less than unity. Labor and materials are complements in apparel production, but there is evidence of substitution between capital and labor. The rate of technical change is higher in textiles than in apparel. Given the intense import competition from low wage countries, in both industries, technical progress is labor saving. Overall, economies of scale are larger in apparel; however, scale economies have continued to increase in textiles.This research was supported by a grant from the National Textile Center.

FIRM AND GOVERNMENT AS ACTORS IN PENROSE'S PROCESS THEORY OF INTERNATIONAL GROWTH: IMPLICATIONS FOR THE RESOURCE-BASED VIEW AND OWNERSHIP–LOCATION– INTERNATIONALISATION PARADIGM

Edith Penrose's The Theory of the Growth of the Firm proposed a process theory of growth based on the pursuit of knowledge by the firm and unconstrained by government. In her subsequent studies of foreign direct investment by large firms in developing countries, Penrose considers the firm and government as actors in the same growth process. This paper explores the development of Penrose's expanded process theory of growth from 1955 to 1973 in which she assumes that neither dual actors nor foreign expansion requires a new or special theory. This finding has implications for the resource-based view and the eclectic ownership–location–internationalisation paradigm interpretations of international business.     

Vertical Integration,Foreign Multinationals and Stigler's Hypotheses: An Empirical Test Using Malaysian Data*

In this paper the hypotheses on motives for vertical integration as proposed by Stigler are empirically tested using a panel dataset from Malaysian manufacturing under both fixed‐effects and random‐effects specifications. Because the degree of multinational participation is expected to influence the results of the regression estimates, empirical tests are conducted with and without controlling for the effect of foreign firms’ participation. Depending on model specifications, evidence is found in favor of Stigler's hypotheses where vertical integration is positively related to demand growth and industry concentration. This result is generally consistent with those found in other vertical integration studies. Significantly, the coefficient estimates of the growth variable are not significant and biased downwards if there is no control on the effect of foreign multinationals in the estimation process.     

Religious minorities and firm ownership in early twentieth‐century Egypt

This article examines the composition of firm ownership and entrepreneurship in Egypt between 1910 and 1949 by assembling a novel dataset on multi‐owned firms. The evidence supports two main results. First, Muslim participation remained disproportionately low in partnerships but was distinctly high in corporations relative to non‐Muslims. Second, Muslim‐owned firms were frailer and more likely to experience early exits. The findings are consistent with the view that the region's institutional legacy, such as disparities in physical or human capital, created obstacles for Muslims. When these implications are tested, the findings show that only small‐scale Muslim firms had restricted access to capital. The skewness in Muslim firms’ entry and start‐up size is probably the result of legal distortions introduced by the government, which entrenched a small class of political elites in large‐scale firms.     

Unemployment persistence

We estimate dynamic panel data models of unemployment incidencefor men using the British Household Panel Survey. Econometricissues concerning unobserved individual heterogeneity, genuinestate dependence, and the initial conditions problems are addressedin detail. We find strong evidence of state dependence consistentwith the scarring theory of unemployment - an individual's previousunemployment experience has implications for his future labourmarket experience. This suggests that policies reducing shortrun employment incidence will have longer-run effects by reducingthe equilibrium or natural rate of unemployment.     

On public investment, long-run growth, and the real exchange rate

This paper extends the Barro (1990) endogenous growth modelwith productive government services to a two-country world withperfect capital mobility, populated by optimising agents withuncertain lifetimes. It shows that increases in government spendingon infrastructure for the home country result in higher growthrates and a terms of trade improvement. Both these effects arereversed after a point, showing that a hump-shaped curve—similarto the Barro curve, but with different properties—canbe obtained here even with lump-sum taxes. We also examine thewelfare implications of public investment policies, and characterisethe world economy's dynamics.     

Cartel Organization,Price Discrimination,and Selection of Transatlantic Migrants: 1899–1911

We study the effects of trans‐Atlantic passenger shipping cartels on tourist/business and migrant traffic. Collusion had a smaller effect on first and second class service relative to third class service. Its effects were proportionately stronger eastbound, but less important in absolute numbers given smaller eastbound traffic. Collusion‐driven consumer substitution across classes was small but non‐negligible. Thus, collusion affected migrant traffic far more than tourist/business traffic. We also confirm that collusion led to higher fares across all cabin classes, especially for steerage. We construct and calibrate an analytical model and show that the pattern of observed prices and volumes are consistent with a profit‐maximizing cartel, thus buttressing the hypothesis that the collusion effects were causal. Finally, we document that collusion led to positive selection of migrants, as measured by literacy rates and financial resources.     

Monastic mortality: Durham Priory, 1395–15291

This article presents reliable data on the life expectancy of the monks of Durham Priory between 1395 and 1529. The number of years that monks survived in this northern monastery plunged precipitously in the second half of the fifteenth century before staging a partial recovery in the early sixteenth. The experience of Durham monks mirrors the scale, direction, and timing of the data already produced for the monks of Canterbury and Westminster. While the precise relationship between monastic mortality and that of the population at large remains difficult to determine, there can be no doubt that the symmetry that has been established between mortality in three monasteries located in different parts of the country has important implications for our understanding of the demographic history of late medieval England.     

THE EFFECTS OF THE TOBACCO PRODUCTS CONTROL AMENDMENT ACT OF 1999 ON RESTAURANT REVENUES IN SOUTH AFRICA: A PANEL DATA APPROACH

Prior to the implementation of this legislation the restaurant industry lobbied that a full‐scale ban would severely hurt business. Their lobbying resulted in a restrictive restaurant smoking policy rather than a full‐scale ban. Nevertheless the industry argued that this would still severely hurt business citing international evidence in support. The objective of this paper is to investigate the change in restaurant revenues after the implementation of a public smoking ban in South Africa. We use a fixed effects panel model to explore the response of restaurant revenues to the imposition of the ban. Provincial data is used over the period 1995 to 2003 and VAT receipts are used as a proxy of restaurant turnover. We conclude that restrictive restaurant smoking policies have not had a negative effect on restaurant revenue, indicating that claims of countrywide restaurant business declines under such a policy are unwarranted.     

Does Human Capital Protect Workers against Exogenous Shocks? Evidence from Panel Data on South Africa during the 2008‐2009 Crisis

The financial and economic crisis of 2008 and 2009 took a heavy toll on the South African economy. The economy contracted for the first time since 1998 and entered recession during the fourth quarter of 2008. The gross domestic product contraction was soon transmitted to the labour market. Between the second quarters of 2008 and 2009, employment fell by 3.8%. However, not all individuals were hit with the same intensity. Using panel data from a quarterly labour force survey unique in the African context, we find that human capital (i.e. education as years of schooling and workforce experience) provided a buffer against the shock. After controlling for observable characteristics, education and experience showed the potential to entirely offset the effect of the recession on the likelihood of employment. This has important policy implications, as it strengthens the case for strategic investments in human capital and helps identify the unskilled as having the greatest need for social safety net interventions during a recession.     

Screening for Managerial Objectives

The debate between agency and stewardship theorists on the nature of managerial objectives in itself implies that a principal may be uninformed about managers' objectives. This article introduces a model of adverse selection in managerial types where classically opportunistic agents are contrasted with stewards who exhibit intrinsic preferences for the organization's success and experience betrayal (crowding out) when they are incentivized as if they were agents. The analysis characterizes stewardship inefficiencies not previously identified by stewardship theorists. This inefficiency is minimized via a menu of contracts that emphasizes the fixed component of pay for stewards. Moreover, steward‐run firms are more successful than agent‐run firms.     

Economies of scale and optimal capital in nuclear and fossil fuel electricity production

This paper tests for economies of scale in the electric utility industry using a five-year panel data set that includes both fossil fuel and nuclear fuel electricity generation. In addition, a variable cost function is used as opposed to a total cost function because the assumption of cost-minimizing production inputs is not met. That is, electric utilities are overcapitalized. Therefore, the optimal capital stock is estimated, which is significantly less than the actual capital stock, and an estimate of economies of scale is generated. Evidence suggests that firms are operating on the negatively sloped portion of the long-run average cost curve near the trough. This indicates either slight economies of scale or no economies of scale.     

Digital finance and household carbon emissions in China

Sustained economic growth and environmental degradation are two of the key goals in the SDGs (Sustainable Development Goals). Digital finance provides an opportunity to simultaneously address the trade-off between the two goals. Based on data from CEADs, CNBS, CFPS, IDFPU, VIIRS and NPCGIS, this article examines the causal impact and transmission mechanisms of digital finance on consumption-based HCEs. To address the potential endogeneity, IV and IV-MA as well as HDFE models are applied in empirical estimates. Results show that digital finance has a positive impact on consumption-based HCEs. Mechanism analysis indicates that digital finance can increase HCEs through stimulating consumption scale, which is scale effect. Besides, digital finance can decrease HCEs through promoting greener consumption patterns, which is composition effect. On the whole, scale effect prevails composition effect. Our findings contribute to the literature on digital finance and green finance and have policy implications on common prosperity, not only for China, but also for other economies.     

Revisiting the Phillips curve for Indonesia: What can we learn from regional data?

This study seeks new empirical evidence of the Phillips curve in Indonesia, an emerging and geographically diversified economy. There are three important contributions from this research. First, applying panel econometric method to exploit regional variation, the study resolves the issue of using on-target national inflation rates that potentially causes weakening inflation-output link. Second, the research examines the relevance of mining industry for output gap measurement at regional level. Third, it highlights the differences in the Phillips curve between the west and east regions owing to their different underlying economic structures. Our estimation using regional data support the validity of the Phillips curve relationship in Indonesia. Backward-looking inflation expectations, exchange rate dynamics and international prices also significantly affect inflation. In addition, the effect of output gap on inflation is larger if the mining sector is excluded from output gap measurement. Finally, we find apparent differences between the west and the eastern regions in the slope of Phillips curve, as well as in the degree of inflation persistence and exchange rate pass-through. The results are robust to alternative specification. Our study adds significantly to the empirical literature on the Phillips curve and have meaningful policy implications.     

Protecting infant industries: Canadian manufacturing and the national policy, 1870–1913

Infant industry protection has been the cornerstone of a debate on tariff policy that extends at least from the eighteenth century to the current day. In contrast to traditional neo-classical models of international trade that imply net negative effects, industrial organization and learning-by-doing trade models describe how protective tariffs can encourage output expansion, productivity improvement, and price reductions. Taking Canada's 1879 National Policy as a natural experiment, we explore the effect of a policy that substantially increased tariff protection to some, but not all, Canadian manufacturing industries. Using treatment intensity and difference-in-differences approaches, we find strong support for the predictions of the new trade models. After 1879, industries that received greater protection experienced faster growth in output and productivity, as well as larger price reductions. The industries targeted by the National Policy also exhibited greater returns to scale and faster learning rates. These results have important implications for the infant-industry debate in addition to addressing a central theme in Canadian economic history,     

Does institutional freedom matter for global forest carbon sinks in the face of economic development disparity?

Mitigating global warming is the responsibility of all countries. Moreso, the role of forests in sequestrating carbon is very crucial. Most environmental organizations are active in protecting the environment according to their objectives. This paper investigates the relationship between institutional freedom and forest carbon sinks by using a panel threshold model with 139 countries to verify the U-shaped relationship between forest carbon sinks and economic development. The U-shaped curve between forest carbon sinks and economic development is the same as the environmental Kuznets curve. The impact of institutional freedom on forest carbon sinks under different economic development thresholds is analyzed. Institutional freedom harms forest carbon sinks when the country experiences lower economic growth. Further analysis shows that when economic development is high, there are positive effects, and the beneficial effects of institutional freedom on the forest carbon sink gradually enhance as the threshold value increases. The article clarifies the relationship between institutional freedom and forest carbon sinks and also provides implications for making forest management strategies and climate mitigation policies.
