Stock and Industry Return Characteristics Around Price Shocks

The author investigates positive and negative price shocks in individual securities and the degree to which they affect related firms in the same industry. This price contagion effect is significant with initial price shocks leading to substantial long-term abnormal returns across firms in the same industry over time. Price shocks also have predictive value regarding future earnings and revenues for the firm in question and its industry overall. Positive (negative) price shocks that are continued over time are associated with higher (lower) Sharpe ratios suggesting that abnormal returns are not simply a form of compensation for greater expected future volatility.     

Stock price synchronicity to oil shocks across quantiles: Evidence from Chinese oil firms

This paper investigates behaviour of stock price synchronicity to oil shocks across quantiles for Chinese oil firms. The spillover effects of the oil market on a firm are segregated into firm-specific and market-wide information. First, our results report a higher level of synchronicity by dynamic conditional correlations than by R-square since the former better captures dynamic linear dependence. Second, we find strong evidence of size effect. In particular, stock price synchronicity is generally higher in large-cap firms than in small-cap ones. Oil shocks affect synchronicity in the upper quantiles differently based on firm size. Third, we also find that synchronicity responds to oil shocks significantly in extreme low quantiles, implying that shocks in the oil market are transmitted to Chinese oil firms via firm-specific information. Finally, we determine that oil shocks have little or no immediate impact on stock price synchronicity; instead, cumulative lagged effect is evident. This evidence highlights the lagging effect of spillover of oil shocks on Chinese oil firms.     

Firm Location and the Creation and Utilization of Human Capital

This paper presents a theory of location choice that draws on insights from the incomplete contracts and investment flexibility (real option) literatures. Our analysis indicates that the choice of locating within rather than away from industry clusters is influenced by the extent to which training costs are borne by firms versus employees. In addition, the uncertainty about future productivity shocks and the ability of firms to modify the scale of their operations also influence location choice. In particular, we show that locating in clusters is preferred when training costs are borne by workers and when firm-specific productivity shocks can potentially be large. However, there is an incentive for firms to choose isolated locations when significant training costs are borne by firms.     

Monetary shocks,equity returns and volatility: a firm-level panel data analysis

This article studies the impact of monetary policy shocks on equity returns and their volatility among nine industries and their affiliated firms in the United States. We use an extension of the traditional CAPM as the analytical framework and approximate policy shocks with the unexpected component of the federal funds rate. Data on the characteristics of firms and industries are obtained from Compustat and the Center for Research in Security Prices, covering a sample period from 1987 to 2009. Our results clearly show that responses to policy shocks vary by industry and across firms. Furthermore, credit availability matters in certain industries, and small, financially constrained, and bank-dependent firms are found to be more vulnerable to unexpected federal funds rate shocks.     

International contagion through financial versus non-financial firms

The role of financial firms in the transmission of financial shocks across countries is well recognized in the literature. However, contagion through non-financial firms has not received much attention. This study examines the role of financial vis-à-vis non-financial firms in transmitting shocks across countries using a dynamic conditional correlation analysis. We provide empirical evidence from a sample of 49 countries. A novel finding of our study is that non-financial firms play a more pronounced role in the cross-market transmission of shocks than financial firms. Financial contagion is positively related to the level of equity market development and bilateral trade intensity. It is higher during periods of US economic downturns and financial crises. Given that the extent of international contagion varies across economic states and is more prevalent in the non-financial than in the financial sector, this study has implications for global sector rotation strategies.     

Within‐firm wage inequality and firm‐level exports

This paper analyzes changes in within‐firm inequality of hourly wages arising from export shocks to exporting firms in Denmark. We provide causal evidence that export demand shocks increase within‐firm inequality. Decomposing overall inequality into within and between components for occupational and educational groups, the results show that exports lead to a significant increase in within‐group wage inequality but do not affect the between‐group component. We develop a partial equilibrium model, featuring heterogeneous workers, which rationalizes these observations and shows how export demand shocks induce a complementarity effect, leading to increases in wage inequality within firms.     

Firm‐Specific Learning and the Investment Behavior of Large and Small Firms*

We examine a model of size distribution and growth of firms where firms learn about idiosyncratic productivity parameters through their production experience. Aggregate shocks, by adding noise to learning at the firm level, can produce different responses across firms. In particular, young firms, which are smaller on average than older firms and more uncertain about their productivity, can “overreact” to aggregate shocks. Such differences across firm sizes and ages, which arise here in a model with perfect financial markets, are often attributed to financial frictions that hit small and large firms differently.     

Bank loan supply shocks and leverage adjustment

We investigate the effect of bank loan supply shocks on firms’ leverage adjustment. We show that the impact of bank shocks is larger for firms with greater dependence on financially troubled banks. We measure firms’ pre-crisis loan dependence on troubled banks by using matched firm–bank loan data. Using the boom-bust cycle from 1987 to 2014 in Japan as a quasi-experiment, we find that financially constrained firms adjust their leverage slower during credit-crunch periods than during other periods. During credit-crunch periods following banking crisis, firms associated with failing banks or with banks that have a limited capacity to supply loans show a slower adjustment than other firms. Bank shocks have significant effects on small firms’ adjustment but not on that of large firms. These results are robust when we consider demand-side effects and perform other robustness tests. Our results imply that bank shocks have a persistent effect on borrowers’ leverage.     

Local linkages: The interdependence of foreign and domestic firms in Ireland

This paper contributes to the literature on backward linkages—the degree of localization in input usage, focusing on the potential interdependence between foreign and domestic producer firms. Drawing on Irish sectoral data during 2000–2013, our main objective is to empirically examine how foreign and domestic producer firms' backward linkages might dynamically influence each other, and the extent to which they respond to export intensity and productivity levels from the two groups of firms. We find an interesting asymmetric interdependence pattern: (1) domestic firms' backward linkages are not impacted by the backward linkages of foreign firms; (2) more robust backward linkages of domestic firms can potentially induce more backward linkages from foreign firms; and (3) domestic firms' productivity shocks could generate a dynamic crossover impact on foreign firms' backward linkage status, but similar shocks originating from foreign firms generate little crossover impact on domestic firms’ backward linkage status. Our result on interdependent local linkages points to a potentially important role for domestic-to-domestic backward linkage formation in promoting foreign-to-domestic backward linkages.     

Taxes and firm investment

We investigate the firm-level investment response to unanticipated narrative shocks to average personal and corporate tax rates using a universal micro dataset of publicly-traded U.S. firms for the post-1976 period. Using local projections, we show that: (i) corporate tax shocks have significant effects on investment while personal tax shocks do not; (ii) corporate income tax responses are negative overall, and this result is driven by smaller firms who face larger borrowing constraints, especially when the accompanying monetary policy is contractionary or output gap is slack; (iii) there is some evidence of positive personal income tax responses during monetary contractions by dividend-paying firms, which is consistent with the recent literature.     

PRICE SETTING PRACTICES IN GREECE: EVIDENCE FROM A SMALL‐SCALE FIRM‐LEVEL SURVEY

The paper documents the price setting practices followed by some 400 or so firms operating in Greece. Survey replies reveal a low percentage of firms changing prices with frequency higher than annual and staggering of price changes during the year. As to firms’ reactions to unexpected shocks, prices appear to adjust sluggishly to cost shocks with asymmetries in price adjustment across positive and negative shocks. Adjustments to increases in costs appear speedier than those to reductions in demand. The data confirm a result found for other countries: the existence of cross‐sectional variations in price setting strategies and in the extent to which prices are adjusted in reaction to unexpected shocks. The results suggest a positive association between, on the one hand, product market competition and, on the other hand, state‐dependent pricing, frequent price changes and the likelihood of a price adjustment following an adverse demand shock.     

Uncertainty and Investment Dynamics

This paper shows that with (partial) irreversibility higher uncertainty reduces the responsiveness of investment to demand shocks. Uncertainty increases real option values making firms more cautious when investing or disinvesting. This is confirmed both numerically for a model with a rich mix of adjustment costs, time-varying uncertainty, and aggregation over investment decisions and time and also empirically for a panel of manufacturing firms. These "cautionary effects" of uncertainty are large—going from the lower quartile to the upper quartile of the uncertainty distribution typically halves the first year investment response to demand shocks. This implies the responsiveness of firms to any given policy stimulus may be much weaker in periods of high uncertainty, such as after the 1973 oil crisis and September 11, 2001.     

COOPERATIVE FIRMS AND THE CRISIS: EVIDENCE FROM SOME ITALIAN MIXED OLIGOPOLIES

We investigate how cooperative firms reacted to the current crisis. This allows us to compare the behaviour of cooperative and conventional firms facing exogenous shifts in demand. After a short survey of a stream of theoretical literature, we analyze a large group of Italian production cooperatives in the periods 2003–2010 and 1994–2011 and we contrast co‐ops behaviour with the overall trend in the industries in which they operate. Our sample's evidence suggests that the cooperative's behaviour has a stabilizing effect on employment with respect to shocks in output demand. Unlike profit‐maximizers, cooperative firms seem to be adjusting pay more than employment when facing shocks. Production co‐ops look better equipped than their profit‐maximizing counterparts in tackling the long recession also because they have been very cautious in their profit policies over time. Unlike conventional firms, they have significantly increased their own equity during ‘good’ years instead of distributing large dividends to their members.     

Bank lending and the stock market's response to monetary policy shocks

This paper explores whether a limited participation model modified to include features of the bank lending channel can account for the empirically observed reaction of stock market returns to monetary policy shocks. When calibrated to match characteristics of US data, the model generates responses that broadly match the empirical counterparts. The results also suggest, that the higher exposure of bank-dependent firms to liquidity shocks generates substantial heterogeneity of the responses across firms.     

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.     

Bank behavior, incomplete interest rate pass-through, and the cost channel of monetary policy transmission

This paper employs a New Keynesian DSGE model to explore the role of banks within the cost channel of monetary policy transmission for shaping the interest rate pass-through from money market rates to loan rates. Banks extend loans to firms in an environment of monopolistic competition by setting their loan rates in a staggered way, which means that the adjustment of the aggregate loan rate to a monetary policy shock is sticky. We estimate the model for the euro area by adopting a minimum distance approach. Our findings exhibit that (i) financial costs are an important factor for price changes, (ii) frictions in the loan market have an effect on the propagation of monetary policy shocks as the pass-through from a change in money market rates to loan rates is incomplete, and (iii) the strength of the cost channel is mitigated as banks shelter firms from monetary policy shocks by smoothing loan rates.     

What Collusion? Unilateral Market Power as a Catalyst for Countercyclical Markups

This paper presents and tests a simple model of competitive and unilateral market power regimes that yields countercyclical markups. Following a decrease in demand in the short run, capacity-constrained firms may have a strong incentive not to lower their prices to the new competitive price. Demand shocks may introduce market power into a previously competitive market. Experimental posted offer markets support this conjecture with complete information on the market structure. With only private information, there appears to be a hysteresis effect concerning supracompetitive prices, i.e., markets with a history of supracompetitive pricing continue to generate supracompetitive prices following demand shocks. However, competitive markets also remain competitive following demand shocks when firms only have private information on costs and capacities.     

NATURAL DISASTERS,DAMAGE TO BANKS,AND FIRM INVESTMENT

This article investigates the effect of banks’ lending capacity on firms’ investment. To identify exogenous shocks to loan supply, we utilize the natural experiment provided by Japan's Great Hanshin‐Awaji earthquake in 1995. Using a unique data set that allows us to identify firms and banks in the earthquake‐affected areas, we find that the investment ratio of firms located outside the earthquake‐affected areas but having a main bank inside the areas was significantly smaller than that of firms located outside the areas and having a main bank outside the areas. Our findings suggest that loan supply shocks affect firm investment.     

Firm resilience in regions of Eastern Europe during the period 2007–2011

Firms are important economic agents in regions, and their survival and prosperity in crisis periods is closely related to the evolution and welfare of the regions in which they are located. This ability of firms to respond to and recover from shocks is conceptualised by the notion of firm resilience. This paper studies the determinants of firm resilience in the regions of Eastern Europe during the period 2007–2011 using a novel, dynamic, spatial and broad conceptual framework aspect. The analysis shows through a variety of determinants that firms of Eastern EU countries have greater resilience, while it also highlights that the resilience of firms is defined, firstly, not only by current structural transformations but also by the initial conditions and, secondly, not only by the firms’ characteristics and capabilities but also by the spatial characteristics and irregularities of their broader environment.     

Collateral constraints and the amplification mechanism

Kiyotaki and Moore (J. Polit. Economy 105 (1997) 211) have offered a theory for how common shocks to credit-constrained firms are amplified through changes in collateral values and transmitted as fluctuations in output. I clarify and extend their model by showing that their collateral amplification mechanism is not robust to the introduction of markets that allow these firms to hedge against common shocks. A theory of incomplete hedging is proposed in which the supply of hedging available in the economy is constrained by the aggregate value of collateral. I illustrate how the constraint reinstates amplification effects and discuss empirical implications of this new mechanism.
