Jealousy and underconsumption in a one-sector model with wealth preference

The present paper examines the effects of consumption externalities on economic performance in a one-sector model with wealth preference. The presence of the wealth preference generates a wealth effect in consumption growth, which plays a crucial role for consumption externalities to have impacts on the economy. Our main findings are: (i) regardless of the assumption of inelastic labor supply, the distortionary effect of consumption externalities stays in the long run; (ii) the income tax as well as the consumption tax can modify the efficiency; and (iii) the numerical simulations supplement theoretical findings.     

Firm-strategic behavior with industry-demand externalities

This paper investigates the effects of industry-demand externalities on the firm's strategic decision making, with an industry-demand externality being defined as a change in industry demand resulting from the efforts of a particular firm to develop, advertise or price a particular product. Profit-maximization models of the firm's strategic behavior that incorporate industry-demand externalities created by a particular firm and the competitive responses of its rivals reveal that the presence of such an externality serves as an incentive for the firm to engage in the form of strategic behavior that generates the externality.     

Existence of marginal pricing equilibria in economies with externalities and non-convexities

We consider a general equilibrium model with externalities and non-convexities in production. The consumption sets, the preferences of the consumers and the production possibilities are represented by set-valued mappings to take into account possibility of external effects. There is no convexity assumption on the correspondences of production. We propose a definition of the marginal pricing rule, which generalizes the one used in the model without externality and, which satisfies a continuity assumption with respect to the external effect.We prove the existence of general equilibria under assumptions which allow us to encompass together the works on economies with externalities and convex conditional production sets, and those on marginal pricing equilibria in economies without externalities. We provide examples to illustrate the definition of the marginal pricing rule and to show the difference with the standard case.     

Direct and indirect effects of FDI in emerging European markets: A survey and meta-analysis

We review a large body of literature dealing with the effects of Foreign Direct Investment (FDI) on economies during their transformation from a command economic system toward a market system. We report the results of a meta-analysis based on the literature on externalities from FDI. The studies on emerging European markets covered in our survey report direct and indirect FDI effects weakening over time, similarly as in other FDI destination countries. This is imputable to a publication bias that is detected and to the fact that more sophisticated methods and more controls can be used once a sufficient time span is available. Panel studies are likely to find relatively lower spillover effects. The choice of the research design (definition of firm performance and foreign firm presence) matters. More specific to the sampled studies is the role played by forward and backward spillovers which dominate other channels in driving FDI externalities.     

Optimal policies in cities with congestion and agglomeration externalities: Congestion tolls,labor subsidies,and place-based strategies

This paper develops a spatial general equilibrium model that accommodates both congestion and agglomeration externalities, while firms’ and households’ land-use decisions are endogenous across continuous space. Focusing on the interaction between externalities and land use patterns, we examine the efficiencies of first-best policies and second-best pricing and place-based strategies using numerical simulations. A first-best policy must combine both Pigouvian congestion tolling (PCT) and Pigouvian labor subsidies (PLS) instruments, or design an optimal toll (or subsidy) internalizing agglomeration externalities (or congestion externalities). We also examine second-best pricing policies if only one instrument is adopted. Congestion pricing policies alone (e.g., a partial PCT or a flat-rate toll) can improve social welfare only in heavy-congestion cities, and their welfare gains may be insignificant (e.g., below 10% of the welfare improvement achieved by first-best policies). In contrast, second-best labor subsidy policies alone are a more effective alternative to first-best policies. As to place-based policies, the firm cluster zoning (FCZ) regulation is more efficient than the urban growth boundary (UGB) policy. UGBs only have small effects on the agglomeration economy but could worsen land market distortions via residential rent-escalation effects. These findings suggest that it is important to internalize business land use decisions and relax monocentricity assumptions, in order to appreciate the interplay of both urban externalities, since spatial adaptations to policy interventions can distort system efficiencies.     

Regulation of road accident externalities when insurance companies have market power

Accident externalities that individual drivers impose on one another via their presence on the road are among the most important external costs of road transport. We study the regulation of these externalities when insurance companies have market power. Some of the results we derive have close resemblance to the earlier literature on externality regulation with market power in aviation and private roads, but there are important differences, too. Using analytical models, we compare the first-best public welfare-maximizing outcome with a private profit-maximizing monopoly, and oligopoly. We find that insurance companies will internalize some of the externalities, depending on their degree of market power. We derive optimal insurance premiums, and regular parametric taxes as well as “manipulable” ones that make the companies set socially optimal premiums. The latter take into account that the firm tries to exploit knowledge of the tax rule applied by the government. Finally, we also study the taxation of road users rather than that of firms.     

Survival of entrepreneurial firms: the role of agglomeration externalities

This paper analyzes the role of various types of agglomeration externalities on the survival rate of entrepreneurial firms. In particular, we trace the population cohort of newly-established and self-employed Swedish firms in the Knowledge-Intensive Business Service sector in 1997 up to 2012 and investigate the role of Marshallian and Jacobian externalities on the survival of these firms. We find that only Jacobian externalities (diversity) is positively associated with the survival of entrepreneurial firms. Not all Jacobian externalities matter though. Only the higher the ‘related variety’ of the region in which an entrepreneurial firm is founded, the higher will be the survival chance of the firm, while ‘unrelated variety’ barely has any significant correlation. The result is robust after controlling for extensive firm characteristics and individual characteristics of the founders. The main message here is: for a newly-established entrepreneurial firm, not only it matters who you are, but also where you are.     

A modified deferred acceptance algorithm for many-to-one matching markets with externalities among firms

We consider a many-to-one matching market with externalities among firms where each firm’s preferences satisfy substitutability, increasing choice and no external effect by unchosen workers, which are defined by  Bando (2012). We first illustrate that a sequential version of the deferred acceptance (DA) algorithm with worker-proposing may not find a worker-optimal quasi stable matching. Then, we provide a modified DA algorithm in which (i) each worker simultaneously proposes to his most preferred firm that has not rejected him and (ii) each firm chooses its acceptable workers from the cumulative set of workers who have ever proposed to it, assuming that the other workers proposing to its rival firms are hired. We show that this algorithm finds a worker-optimal quasi stable matching. We also show that this algorithm can be generalized into a fixed point algorithm.     

Local and global indeterminacy in two-sector models of endogenous growth

We consider a two-sector endogenous growth model where the productions of the final good and human capital require economy-wide external effects. Assuming constant returns to scale at the private and social levels, we show that local and global indeterminacy of equilibrium paths are compatible with any values for the elasticity of intertemporal substitution in consumption and any sign for the capital intensity difference across the two sectors. We also show that for any value of the elasticity of intertemporal substitution in consumption, poverty traps may occur when the final good sector is capital intensive in human capital.     

Trade,redistribution and indeterminacy

In the present paper a tractable two-sector growth model with technological externalities and many countries is considered. It is shown that the occurrence of indeterminacy, a typical side-product of externalities, may appear due to the enlargement of the markets for goods and factors. Various scenarios of progressive levels of integration are considered. In particular, it is found that the integration into a common market on which countries trade the produced good and the inputs may lead to indeterminacy even when the equilibrium under full autarchy is determinate. A similar result holds when integration only affects consumption and capital goods. However, such result does not occur if the inverse of relative risk aversion is a linear or concave function. We conclude that in many usual situations, as the one with CES preferences, indeterminacy and the associated fragility of expectations and financial instability, is not likely to be increased by market integration.     

Congestible public goods and local indeterminacy: A two-sector endogenous growth model

This paper shows that the congestible public goods can generate local indeterminacy in a two-sector, constant-return human capital enhanced growth model. While the productive public good exerts positive sector-specific externalities, the congestion effect generates negative aggregate externalities. The sector-specific externalities alone arising from productive public goods cannot establish local indeterminacy without the combination of negative externality in a model with social constant return technology. Congestible public good generates local indeterminacy if the degree of productive public good externality and the degree of congestion effect are large enough. The condition for indeterminacy is independent of the factor intensity rankings. The conditions are quantitatively assessed and the required parameter values for the degrees of public good externality and congestion are consistent with the estimated values in existing literature.     

Geographic poverty traps? A micro model of consumption growth in rural China

How important are neighbourhood endowments of physical and human capital in explaining diverging fortunes over time for otherwise identical households in a developing rural economy? To answer this question we develop an estimable micro model of consumption growth allowing for constraints on factor mobility and externalities, whereby geographic capital can influence the productivity of a household's own capital. Our statistical test has considerable power in detecting geographic effects given that we control for latent heterogeneity in measured consumption growth rates at the micro level. We find robust evidence of geographic poverty traps in farm‐household panel data from post‐reform rural China. Our results strengthen the equity and efficiency case for public investment in lagging poor areas in this setting. Copyright © 2002 John Wiley & Sons, Ltd.     

Linear production function,externalities and indeterminacy in a capital-resource growth model

This paper investigates the equilibrium growth dynamics of an economy whose production is based on natural resources and which seeks to maximize welfare to the local community. This involves determining the optimal trajectories of consumption in the local area and the use of the environmental resource. Economic dynamics are affected by negative environmental externalities which are explicitly included as unfavourable effects in a linear production function. The analysis shows the existence of local and global indeterminacy.

Elements of an economic justification for municipal zoning

The possibility that externalities will produce a nonconvexity in the social production set limits the application of both the Coase and Pigou solutions for achieving an optimal allocation of land resources. Conditions on relative land prices are derived which indicate that external effects are strong enough to introduce a nonconvexity into the production set. These conditions were not fulfilled in a sample of single-family and multifamily dwellings in Foster City, California. This does not preclude the possibility that they are fulfilled in cases of more severe external effects.

The impact of open innovation on firm performance: The moderating effects of internal R&D and environmental turbulence

Researchers have identified open innovation as two dimensions, external technology acquisition and external technology exploitation. This study explores the direct and interactive effects of these two dimensions on firm performance and further examines the moderation effects of two factors (i.e., internal R&D and environmental turbulence) on the relationship between both types of open innovation and firm performance. Based on Chesbrough's open innovation model, multi-item scales were developed to measure two dimensions of firm-level open innovation. Survey results of 176 Taiwanese high tech manufacturing firms provide support for most hypotheses. The result shows that external technology acquisition positively affects firm performance, whereas external technology exploitation does not. This study also finds that external technology acquisition strengthens the relationship between external technology exploitation and firm performance. Both external technology acquisition and external technology exploitation are positively related to firm performance under high internal R&D investment and a turbulent market environment. However, technological turbulence only positively affects the relationship between external technological acquisition, but not external technology exploitation, and firm performance. The findings contribute to enhanced understanding of how the degree of leveraging open innovation dimensions depends on their complementarity, internal R&D, and environmental turbulence.     

Is expatriation good for my career? The impact of expatriate assignments on perceived and actual career outcomes

This study examines the impact of expatriate assignments on career growth and the external marketability of US employees of a large professional services firm. We use survey and archival data to compare expatriates currently overseas, repatriates, and domestic US employees on compensation, recent promotions, and external recruiting contacts. We then examine how actual pay, promotions, and external recruiting influences anticipated salary growth within the firm and external employment opportunities. We find that despite little or no impact on their current careers, employees with overseas work experience perceived greater internal and external opportunities than domestic US employees. Implications for managers and researchers are discussed.     

The creative response and the endogenous dynamics of pecuniary knowledge externalities: an agent based simulation model

The paper elaborates an agent based simulation model (ABM) to explore the endogenous long-term dynamics of knowledge externalities. ABMs, as a form of artificial cliometrics, allow the analysis of the effects of the reactivity of firms caught in out-of-equilibrium conditions conditional on the levels of endogenous knowledge externalities stemming from the levels of knowledge connectivity of the system. The simulation results confirm the powerful effects of endogenous knowledge externalities. At the micro-level, the reactions of firms caught in out-of-equilibrium conditions yield successful effects in the form of productivity enhancing innovations, only in the presence of high levels of knowledge connectivity and strong pecuniary knowledge externalities. At the meso-level, the introduction of innovations changes the structural characteristics of the system in terms of knowledge connectivity that affect the availability of knowledge externalities. Endogenous centrifugal and centripetal forces continually reshape the structure of the system and its knowledge connectivity. At the macro system level, an out-of-equilibrium process leads to a step-wise increase in productivity combined with non-linear patterns of output growth characterized by significant oscillations typical of the long waves in Schumpeterian business cycles.     

Two state capital accumulation with heterogenous products: Disruptive vs. non-disruptive goods

The paper considers the problem of a firm that, while producing a standard product, has the option to introduce an innovative product. The innovative product competes with the standard product and will therefore reduce revenues of the standard product. A distinction is made between innovative products that do or do not become even more relatively appealing as their market share grows (e.g., because of network externalities). It is shown that in the former case, which we call a “disruptive” good, history dependent long run equilibria can occur, which are in line with recent real life economic examples.
