Collateral and capital structure

We develop a dynamic model of investment, capital structure, leasing, and risk management based on firms' need to collateralize promises to pay with tangible assets. Both financing and risk management involve promises to pay subject to collateral constraints. Leasing is strongly collateralized costly financing and permits greater leverage. More constrained firms hedge less and lease more, both cross-sectionally and dynamically. Mature firms suffering adverse cash flow shocks may cut risk management and sell and lease back assets. Persistence of productivity reduces the benefits to hedging low cash flows and can lead firms not to hedge at all.     

Stock market boom and the productivity gains of the 1990s

Together with a sense of entering a New Economy, the U.S. experienced in the second half of the 1990s an economic expansion, a stock market boom, a financing boom for new firms and productivity gains. This article proposes an interpretation of these events within a general equilibrium model with financial frictions and decreasing returns to scale in production. We show that the mere prospect of high future productivity growth can generate sizable gains in current productivity, as well as the other above mentioned events.     

Inventories, employment and hours

This paper develops a model that integrates inventory and labor decisions. We extend a model of inventory behavior to include a detailed specification of the role of labor input in the production process, distinguishing between employment, hours and effort per worker. We estimate jointly the Euler equations for inventories and employment, a labor compensation schedule, and an hours requirement function with the cross-equation restrictions imposed. The econometric results shed light on several important topics, including the shape of the marginal cost of output, the role of labor hoarding as an explanation of pro-cyclical productivity, and the persistence of inventory stocks.     

Trend breaks, long-run restrictions, and contractionary technology improvements

Structural vector autoregressions with long-run restrictions are extraordinarily sensitive to low-frequency correlations. Recent literature finds that the estimated effects of technology shocks are sensitive to how one treats hours per capita. However, after allowing for (statistically and economically significant) trend breaks in productivity, results are much less sensitive: hours fall when technology improves. The issue is that the common high-low-high pattern of productivity growth and hours (i.e., the low-frequency correlation) inevitably leads to a positive estimated response. The trend breaks control for this correlation. This example suggests a practical need for care in using long-run restrictions.     

Technology Shocks and the Labor-Input Response: Evidence from Firm-Level Data

We study the relationship between technology shocks and labor input on Swedish firm-level data using a production function approach to identify technology shocks. Taking standard steps yields a contractionary contemporaneous labor-input response in line with previous studies. This finding may, however, be driven by measurement errors in the labor-input variable. Relying on a unique feature of our data set, which contains two independently measured firm-specific labor input measures, we can evaluate the potential bias. We do not find that this bias conceals any true positive contemporaneous effect. The results thus point away from standard flexible-price models and toward models emphasizing firm-level rigidities.     

Corporate capital structure and the characteristics of suppliers and customers

We investigate the link between a firm's leverage and the characteristics of its suppliers and customers. Specifically, we examine whether firms use decreased leverage as a commitment mechanism to induce suppliers/customers to undertake relationship-specific investments. We find that the firm's leverage is negatively related to the R&D intensities of its suppliers and customers. We also find lower debt levels for firms operating in industries in which strategic alliances and joint ventures with firms in supplier and customer industries are more prevalent. Consistent with a bargaining role for debt, we find a positive relation between firm debt level and the degree of concentration in supplier/customer industries.     

Investment,internal funds and public banking in Germany

Previous studies supposed that low investment-cash flow sensitivities of German firms may be caused by a dominance of public banking. The paper addresses this assumption and applies a unique accounting dataset of German firms. Results from a dynamic version of the sales accelerator model show that the dependence of investment spending on internal funds does not significantly differ among firms attached to savings banks, cooperative banks or commercial banks. Thus, the importance of the public banking sector in Germany may not explain the rather low dependence of German firms on internal funds, and public ownership of banks does not seem to be important for reducing financing constraints.     

A competitive model of the informal sector

In developing nations, formal workers tend to be more experienced, more educated, and earn more than informal workers. These facts are often interpreted as evidence that low-skill workers face barriers to entry into the formal sector. Yet, there is little empirical evidence that such barriers are important. This paper describes a model where, in equilibrium, the characteristics of formal and informal workers differ systematically, even though labor markets are perfectly competitive. The informal sector emphasizes low-skill work, as in the data, because informal managers have access to less outside financing, and choose to substitute low-skill labor for physical capital.     

Firm Microstructure and Aggregate Productivity

Models of firm microstructure are becoming now a standard building block in macroeconomics, trade, and development. This literature builds on the recognition that firm heterogeneity and the allocation of resources across firms plays a key role in determining aggregate productivity and the gains from trade. Barriers to the efficient allocation of resources across firms have been recently recognized to play a key role in economic development. This paper focuses on this methodological contribution, the link between firm microstructure and economic aggregates.     

Learning and shifts in long-run productivity growth

An extensive literature has analyzed the macroeconomic effects of shocks to the level of aggregate productivity; however, there has been little corresponding research on sustained shifts in the growth rate of productivity. In this paper, we examine the effects of shocks to productivity growth in a dynamic general equilibrium model where agents do not directly observe whether shocks are transitory or persistent. We show that an estimated Kalman filter model using real-time data describes economists’ long-run productivity growth forecasts in the United States extremely well and that filtering has profound implications for the macroeconomic effects of shifts in productivity growth.     

The Relationships between Permanent and Transitory Movements in U.S. Output and the Unemployment Rate

This paper estimates the permanent and transitory movements in U.S. output and the unemployment rate and the relationships between them. The results suggest that permanent movements in U.S. output and the unemployment rate are important for explaining overall fluctuations. Further, the correlation between changes in these series arises in large part due to the relationship between their permanent components.     

Firm dynamics, markup variations, and the business cycle

We present a model in which net business formation is endogenously procyclical. Variations in the number of operating firms lead to countercyclical variations in markups that give rise to endogenous procyclical movements in measured total factor productivity (TFP). Based on this result, the paper suggests a simple structural decomposition of variations in TFP into those originating from exogenous shocks and those originating endogenously from the interaction between firms’ entry and exit decisions and the degree of competition. The decomposition suggests that around 40% of the movements in measured TFP can be attributed to this interaction. Moreover, the paper analyzes the effects on (i) the measurement of the volatility of exogenous shocks in the U.S. economy and (ii) the magnification of shocks over the business cycle.     

Financial constraints on investment in an emerging market crisis

We investigate whether capital market imperfections constrain investment during an emerging market financial crisis. Both large currency devaluations and banking sector failures characterize recent crises. Although a currency devaluation should increase exporters’ competitiveness and investment, a failing banking system may limit credit to these firms. Foreign-owned firms, which may have greater access to overseas financing but otherwise face the same investment prospects, provide an ideal control group for determining the effect of liquidity constraints. We test for liquidity constraints in Indonesia following the 1997 East Asian financial crisis, a period when the issuance of new domestic credit shrank rapidly. Exporters’ value added and employment increased after the crisis, suggesting that they profited from the devaluation and had sufficient cash flow to finance more workers. However, only exporters with foreign ownership increased their capital significantly. Our results suggest that liquidity constraints greatly retarded domestic-owned manufacturing firms’ ability to take advantage of improved terms of trade. Specifically, compared to foreign-owned exporters they had resembled before the crisis, after the crisis domestic-owned exporters had more than 20% lower employment and capital and more than 40% lower value added and materials usage.     

The productivity effects of privatization: The case of Polish cooperatives

This paper evaluates the productivity effects associated with privatization of producer cooperatives. The results, based on a sample of 2164 Polish cooperatives, indicate that privatized cooperatives have: (1) 1% lower total factor productivity (TFP) the year prior to privatization and 3-20% higher TFP in the year of privatization and three years post-privatization, (2) 9-36% higher labor productivity, (3) capital productivity effects of − 16-6%. The evidence is consistent with governance and incentive mechanisms of cooperatives being more effective outside of state interference, and with competition and hard budget constraints leading to pressure to restructure and adopt practices that improve productivity.     

India's pattern of development: What happened, what follows?

India has followed an idiosyncratic pattern of development, certainly compared with other fast-growing Asian economies. While the importance of services rather than manufacturing has been widely noted, within manufacturing India has emphasized skill-intensive rather than labor-intensive manufacturing, and industries with higher-than-average scale (though average firm size within industries is unusually small). Some of these distinctive patterns existed prior to the beginning of economic reforms in the 1980s, and stem from the idiosyncratic policies adopted after India's independence. These patterns have not changed despite reforms that have removed some policy impediments that contributed to India's distinctive path. We discuss the implications for India's future growth.     

Are elite universities losing their competitive edge?

We study the location-specific component of research productivity for economics and finance faculty over the last three decades. We find that there was a positive effect of being affiliated with a top 25 university in the 1970s; this effect weakened in the 1980s and disappeared in the 1990s. The decline in elite university fixed effect is due to the reduced importance of physical access to productive research colleagues, which in turn seems due to innovations in communication technology. One implication is that knowledge-based organizations should find it more difficult to capture rents vis-à-vis workers. We find that faculty salaries increased the most where the estimated spillover dropped the most. Despite the loss in local spillovers, elite universities still enjoy an edge in average productivity because of agglomeration of top researchers in prestigious institutions with high long-term research reputations.     

Ownership and Production Costs: Choosing between Public Production and Contracting‐Out in the Case of Swedish Refuse Collection

Many comparisons of public and private firms use a public/private ownership dummy variable to capture cost differences. If, however, public and private firms use different production technologies, the dummy‐variable approach is misspecified. Data from public and private firms should not be pooled. Secondly, selectivity bias may arise, making it more difficult to identify cost differentials that actually exist. Thirdly, if data should be pooled, the resulting empirical model may be logically inconsistent. This paper compares public and private firms using the refuse collection costs of 170 firms in 115 Swedish municipalities. First, public production costs were 6 per cent lower than private production costs. Secondly, cost differences did not affect producer choice. It is crucial to adjust for selectivity. Data for private and public firms should not be pooled. The dummy‐variable model is misspecified.     

Technological innovation and real investment booms and busts

We investigate why new, high-risk technologies can attract excessive and often unprofitable investment. We develop an equilibrium model in which rational, risk-averse agents overinvest in a risky technology, possibly to the point that its expected return is negative. Overinvestment results from relative wealth concerns which arise endogenously from the imperfect tradability of future endowments. Competition over future consumption leads to an indirect utility for wealth with “keeping up with the Joneses” properties that can induce herding. Because overinvestment increases with the risk of the technology, our model can explain why new, risky technological innovations may promote investment bubbles.     

Investment dynamics with fixed capital adjustment cost and capital market imperfections

This paper examines the implications of financing frictions on capital stocks and on capital accumulation in the presence of non-convex costs of adjusting the capital stock. In this setup finance has an influence on both, the level of capital and the timing of investment. Finance and productivity are complements and finance influences investment the strongest when firms wish to significantly adjust capital for fundamental reasons. These theoretical considerations are confronted with UK data. While finance is mostly irrelevant for long-term capital decision, the short-run investment function shows a significant impact of finance, which is also strongest for strong fundamental investment incentives.     

Pricing Behavior and the Response of Hours to Productivity Shocks

Recent contributions have suggested that technology shocks have a negative impact on hours, contrary to the prediction of standard flexible-price models of the business cycle. Some authors have interpreted this finding as evidence in favor of sticky-price models, while others have either extended flexible-price models or disputed the empirical finding itself. In this paper, we estimate a variety of alternative total factor productivity measures for a representative sample of Italian manufacturing firms and on average find a negative effect of productivity shocks on hours growth. More interestingly, using the reported frequency of price reviews, we show that the contractionary effect is stronger for firms with stickier prices and weaker or not significant for firms with more flexible prices. Price stickiness remains a crucial factor in shaping the response of hours after controlling for product storability or market power.
