Debt maturity and firm productivity—The role of intangibles

Does the maturity of debt matter for productivity? Using data on Italian firms from 1997 to 2015, we study the relationship among debt maturity, productivity, and firm characteristics. We find that productivity is positively associated with short-term debt and negatively associated with long-term debt. This result supports the hypothesis that the less intense monitoring of firm performance and fewer liquidation fears stemming from the long maturity of debt causes a moral hazard, while short-term debt serves as a disciplinary device to improve firm performance in the short run. This effect is evident in small- and medium-sized enterprises and old firms. In contrast, large firms can utilize long-term financing to improve productivity through long-term investments. Firms improve productivity by purchasing intangible assets financed by short-term debt.     

Debt overhang in a business cycle model

We study the macroeconomic implications of the debt overhang distortion on firms׳ investment and labor decisions. We show that the distortion arises when the levels of investment and labor are non-contractible and chosen after the signing of the debt contract. The financial friction manifests itself as investment and labor wedges that move counter-cyclically, increasing during recessions when the risk of default is high. Their dynamics amplify and propagate the effects of shocks to productivity, government spending, volatility, and funding costs. Both the size and the persistence of these effects are quantitatively important.     

Trade Liberalization and Productivity Growth

This paper presents a trade model with firm‐level productivity differences and R&D‐driven growth. Trade liberalization causes the least productive firms to exit but also slows the development of new products. The overall effect on productivity growth depends on the size of intertemporal knowledge spillovers in R&D. When these spillovers are relatively weak, then trade liberalization promotes productivity growth in the short run and makes consumers better off in the long run. However, when these spillovers are relatively strong, then trade liberalization retards productivity growth in the short run and makes consumers worse off in the long run.     

A policy model to analyze macroprudential regulations and monetary policy

We construct a small‐open‐economy, new Keynesian dynamic stochastic general‐equilibrium model with real financial linkages to analyze the effects of financial shocks and macroprudential policies on the Canadian economy. The model incorporates rich interactions between the balance sheets of households, firms and banks, long‐term household and business debt, macroprudential policy instruments and nominal and real rigidities and is calibrated to match dynamics in Canadian macroeconomic and financial data. We study the transmission of monetary policy and financial and real shocks in the model economy and analyze the effectiveness of various policies in simultaneously achieving macroeconomic and financial stability. We find that, in terms of reducing household debt, more targeted tools such as loan‐to‐value regulations are the most effective and least costly, followed by bank capital regulations and monetary policy, respectively.     

Country Default Risk: An Empirical Assessment

We provide benchmarks to evaluate what is an optimal foreign debt and a maximal foreign debt ( debt-max ), when risk is explicitly considered. When the actual debt exceeds debt-max , then the economy will default when a 'bad shock' occurs. This paper is an application of the stochastic optimal controls models of Fleming and Stein (2001), which gives empirical content to the question of how one should measure 'vulnerability' to shocks, when there is uncertainty concerning the productivity of capital. We consider two sets of high-risk countries during the period 1978–99: a subset of 21 countries that defaulted on the debt, and another set of 13 countries that did not default. Default is a situation where the firms or government of a country reschedule the interest/principal payments on the external debt. We thereby explain how our analysis can anticipate default risk, and add another dimension to the literature of early warning signals of default/credit risk.     

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.     

PRODUCTIVITY OR UNEXPECTED DEMAND SHOCKS: WHAT DETERMINES FIRMS' INVESTMENT AND EXIT DECISIONS?

We investigate the roles played by unexpected demand shocks, besides productivity, on firms' capital investment and exit decisions. We propose a practical approach to recover unexpected firm‐level demand shocks using inventory data. The recognition of demand shocks and inventory also improves the productivity estimation. The empirical results indicate that although productivity and demand shocks are both significant factors determining firm behavior, the former is more dominant for investment decision and the latter is more salient for firm exit. These findings confirm that unexpected demand shocks, besides persistent productivity, are important factors when analyzing capital investment and firm exit decisions.     

A Model of a Price-setting Duopoly with a Wage-rise Contract

This paper considers a wage-rise contract between a firm and its employees as the firm's strategy, and suggests a wage-rise-contract policy. The policy is a promise by the firm that it will announce a certain output level and a wage premium rate, and if it actually produces more than the announced output level, then it will pay each employee a wage premium uniformly. First, this paper examines the case in which one of two firms unilaterally offers the wage-rise-contract policy by using a two-stage price-setting duopoly model. It is then shown that there exists an equilibrium which coincides with the Stackelberg solution where the firm adopting the policy is the leader. Next, this paper examines the case in which both firms can offer the wage-rise-contract policy in the model. It is then shown that there exists an equilibrium which is more profitable for both firms than in the unilateral case.     

Technology diffusion and growth

Suppose firms are subject to decreasing returns and permanent idiosyncratic productivity shocks. Suppose also firms can only stay in business by continuously paying a fixed cost. New firms can enter. Firms with a history of relatively good productivity shocks tend to survive and others are forced to exit. This paper identifies assumptions about entry that guarantee a stationary firm size distribution and lead to balanced growth. The range of technology diffusion mechanisms that can be considered is greatly expanded relative to Luttmer (2007) [21]. If entrants can make only small improvements over the technologies used by the least productive incumbents, then the firm size distribution approximates Zipf?s law and entry and exit rates are high, as in the data.     

On Emissions Trading and Market Structure: Cap-and-Trade versus Intensity Standards

This paper examines the interdependence between imperfect competition and emissions trading. We particularly analyze the long run equilibrium in a two-sector (‘clean’ and ‘dirty’) model with Cournot competition among firms who face a fixed cost of production. The clean sector is defined as the sector with the highest long run cost margin on emissions. We compare the welfare implications of a cap-and-trade scheme with an emissions trading scheme based on relative intensity standards. It is shown that a firm’s long run equilibrium output in the clean or dirty sector does not depend on the emissions trading format, but only depends on the fixed cost of producing in the respective sector. Intensity standards can result in clean firms selling allowances to dirty firms, or dirty firms selling to clean firms. The former outcome yields higher welfare. It is demonstrated that cap-and-trade outperforms the intensity-based trading scheme in terms of long run welfare with free entry and exit. With intensity standards the size of the clean sector is too large.     

Payment choice in international trade: Theory and evidence from cross‐country firm‐level data

When trading across borders, firms choose between different payment contracts. Theoretically, this should allow firms to trade‐off differences in financing costs and enforcement across countries. This paper provides evidence for this hypothesis employing firm‐level data from a large number of developing countries. As predicted, international transactions are more likely paid after delivery when financing costs in the source country are high and when contract enforcement is low. We extend the theory and also show empirically that the more complex an industry is, the more important is contract enforcement and the less important are financing costs for the contract choice.     

Optimal debt contracts and product market competition with exit and entry

We show how competition in oligopolies, with the possibility of failure and exit of a levered incumbent, affects the ex-ante design of optimal debt contracts. When a levered firm's profits are unobservable, a debt contract imposes the threat of nonrenewal to induce truthful revelation. Because nonrenewal impacts the future profitability of the surviving competitor, the contract influences the competitor's pricing strategy and the equilibrium profits of both firms. The optimal contract is quite different from a standard debt contract, and induces the competitor to be less aggressive, resulting in higher equilibrium prices and profits, and higher returns for investors.     

Productivity Shocks and Real Effective Exchange Rates

This paper provides new insights into the relationship between exchange rates and productivity developments for European Economies. We focus on the question whether productivity changes have a long‐run impact on real effective exchange rates for a large number of European economies. Focusing on a sample period running from 1995 until 2013, we adopt a cointegrated vector autoregressive approach and distinguish between long‐run equilibrium, short‐run dynamics and long‐run impact of shocks. Our findings show that for several industrialized economies, real effective exchange rates and labor productivity are not related over the long‐run. A possible explanation for this result is that wage developments do not reflect increases in labor productivity to a large degree, which prevents a transmission to the real effective exchange rate through the price channel. The results for Central and Eastern European Countries are more encouraging since a positive impact of labor productivity on real effective exchange rate is frequently observed.     

COMPETITIVE LONG RUN INDUSTRY EQUILIBRIUM AND FACTOR-PRICE UNCERTAINTY*

In this paper we have considered competitive long run industry equilibrium with factor-price uncertainty. We discussed the long run equilibrium output of firms with risk neutrality, output price and their responses to changes in uncertainty, factor price and industry demand. In the first part of this paper we have derived a result that, given risk neutrality, the firms operate at proper capacity, i.e. where expected long run marginal cost is equal to expected long run average cost, as shown in the case of output-price uncertainty. This result is, however, different from that obtained from Sheshinski and Dréze (1976). From the comparative static analysis we first discovered that even under risk neutrality factor-price uncertainty affects the long run industry equilibrium: that is, a mean preserving increase in uncertainty leads firm's to enter the industry, because they can decrease expected long run costs as the variability of factor price increases. Consequently, output price goes down. In contrast, firm size is kept invariable in response to its increase as long as the cost function is separable, i.e. the separability of the cost function holds when production functions are the Cobb-Douglas and CES types used commonly in empirical work, although firm size might, generally, be affected by the increase. It is an interesting fact that firm size and industry size will express different responses to a change in risk. The result that the long run industry equilibrium with cost uncertainty is explicitly affected is a sharp contrast to the result under output-price uncertainty and provides a new aspect for understanding about the behaviour of the industry with uncertainty. Secondly, increased factor-price causes the number of firms in the industry to decline and output price to rise. In addition, firm's size will expand with its increase if that factor is inferior, while the effect on firm size is ambiguous if it is normal. The firm's output, i.e. firm size, is, however, kept constant if the cost function is separable. Thirdly, the long run equilibrium output of the firm remains intact but the number of firms increases as industry demand rises. This result holds, regardless of the firm's attitude towards risk. Finally, we find throughout the paper that the functional form of the cost function plays a significant role in determining the behaviour of the industry with factor-price uncertainty.     

LONG‐TERM AND SHORT‐TERM CONTRACT IN A MIXED MARKET*

With a two‐period mixed oligopolistic framework, this paper analyses the interaction between the length of incentive contracts and market behaviour. Assuming an environment in which firms choose either a long‐term or short‐term contract, we examine how contracts differ between public and private firms. The results show that the contracts would differ completely among firms; public firm prefers to make a short‐term contract while private firm makes a long‐term contract.     

政企合谋、环境规制与企业全要素生产率*

本文利用中国工业企业数据库和地级市层面的企业治污投资数据构建了一个2003—2007年的面板,实证检验了环境规制对企业全要素生产率的影响以及政企合谋在背后的作用。实证结果表明,用企业治污投资占工业增加值比重衡量的环境规制强度每上升1%,企业当期的生产率下降约1%。当政企合谋可能性上升时,环境规制对企业生产率的边际影响在减弱,说明政企合谋带来的监管放松和处罚不力弱化了环境规制对合谋企业生产率的影响。本文的政策启示在于中央政府应加强环保领域统一执法,破解囚徒困境式的环境规制。同时,本文的发现为环保机构监测监察执法垂直管理制度改革提供了合理性依据。     

Risk sharing and export performance with firm heterogeneity

We investigate how market uncertainty affects the export performance of a firm through financial frictions. We first extend Melitz's (2003) heterogeneous firm trade model by incorporating demand shocks, linking the demand uncertainties to the financing costs of firms. In this extension, the default probability is endogenously determined by a firm's productivity and demand uncertainty. Hence, firms with higher productivity or lower market uncertainty are offered lower interest rates and thus show better export performance. As an application, we also show that a risk-sharing mechanism, that pools default risk for a certain group of firms, lowers the default risk. This mechanism allows banks to charge lower interest rates to the member firms and therefore ultimately improves their export performance in both extensive and intensive margins. We find a real-world example of such a mechanism from business groups in Korea. Using Korean firm-level data, we show that the more diversified the business group, the greater the likelihood that its member firms export and the bigger their export revenues. We also show that our results are robust to alternative explanations for Korean business groups’ export competitiveness.     

Productivity Performance of Export Market Entry and Exit: Evidence from Indian Firms

This paper contributes to the literature on exporting and firm productivity, focusing on export entry (efficiency), learning (post‐entry growth) and exit (inefficiency) by Indian firms. Drawing on 7000 firms during 1989–2009, our main objective is to examine the effect of exporting on firm productivity, correcting for selection bias using propensity‐score matching, which allows a “like‐for‐like” comparison between new exporters and nonexporters. Robust to different matching estimators, we find evidence of learning‐by‐exporting that new exporters acquire rapid productivity growth after entry, relative to nonexporters. We also find that (1) exporters are more productive than nonexporters; (2) productive firms tend to self‐select in entering the exporting market, and (3) least productive exporters are found to exit the export market as they experience adverse productivity effect prior to the year of exit. Our robust result on learning‐by‐exporting suggests that entering export market does appear to be a channel explaining the Indian recent growth miracle.     

Public Enterprise Privatization: A General Equilibrium Analysis

This paper develops a general equilibrium model to examine the short‐run and long‐run optimal privatization policies. By assuming that all firms are public firms initially, the paper focuses on how the degree of product differentiation γ and the average efficiency of the industry influence the determination of the optimal privatization policy. The paper shows that privatization decreases the more efficient firms' outputs while increases the less efficient firms' outputs in the short run, and reduces all firms' outputs in the long run. The paper also shows that the larger is γ and the smaller is the number of firms, the more privatized will be the public firm in the short run. Moreover, as γ or the entry barrier f_E is sufficiently small, full privatization is the best policy in the long run. On the contrary, as γ and f_E are large enough, partial privatization is optimal.     

Flexible Labour,Firm Performance and the Dutch Job Creation Miracle

Unlike internal (‘functional’) forms of flexibility of labour, external (‘numerical’) forms of flexibility (i.e. high shares of people on temporary contract or a high turnover of personnel) yield substantial savings on a firm’s wage bill. Savings on wage bills lead to higher job growth, but do not translate into higher sales growth. Externally flexible labour appears to be related to lower labour productivity growth, the effects being different for innovating vs non‐innovating firms. We discuss these findings from firm‐level and worker‐level data against the background of the Dutch job creation miracle during the 1980s and 1990s. Modest wage increases and flexibilization of labour markets may indeed create lots of jobs. However, this is likely to happen at the expense of labour productivity growth, raising serious doubts about the long‐run sustainability of a low‐productivity–high‐employment growth path.
