The Role of Product-Level Dynamics in Export Growth and Productivity: Evidence from Estonia

Recent empirical studies of international trade have stressed that firm-level decisions about the number of export products or markets are an important margin of adjustment in response to globalization and changes in economic conditions. We investigate how decisions about the export product mix are associated with aggregate export dynamics and productivity of firms. We use detailed data on product and export market levels for the full population of Estonia's firms. Decomposition analysis of trade flows shows that both the relative importance of firms' beginning to export products and the role of product-level churning (firms' adding and dropping of products) in total Estonian export growth increases significantly after accession to the European Union in 2004. We show that concentration on core competence products has a rather different association with productivity of firms in different-size groups. Large firms with a large number of different types of export products gain, on average, in terms of productivity from concentrating their export sales on their core export products. There is no such general regularity in the case of small firms.     

Measuring aggregate productivity growth using plant‐level data

We define aggregate productivity growth (APG) as the change in aggregate final demand minus the change in the aggregate expenditures on labor and capital. We show how to aggregate plant‐level data to this quantity and how to decompose APG into technical efficiency and reallocation components. This requires us to confront the “non‐neoclassical” features that impact plant‐level data, including plant‐level heterogeneity, the entry and exit of goods, adjustment costs, fixed and sunk costs, and market power. The APG decomposition includes one term per plant related to technical efficiency and one term for each input at each plant that is a function of the value of marginal product ‐ input price gap and that relates the reallocation of inputs to growth. We compare APG to several competing variants of productivity growth that are based only on plant‐level technical efficiency. Two simple theoretical examples illustrate that technical‐efficiency reallocation can be negatively correlated with actual APG reallocation because technical efficiency is a production concept and need not have any relation with the APG reallocation gaps. We illustrate this point empirically using panel data from manufacturing industries in Chile, where we show technical‐efficiency reallocation differs substantially from measured reallocation based on our definition of APG.     

Advertising dynamics and competitive advantage

Can advertising lead to a sustainable competitive advantage? To answer this question, we propose a dynamic model of advertising competition where firms repeatedly advertise, compete in the product market, and make entry as well as exit decisions. Within this dynamic framework, we study two different models of advertising: in the first model, advertising influences the goodwill consumers extend toward a firm (“goodwill advertising”), whereas in the second model it influences the share of consumers who are aware of the firm (“awareness advertising”). We show that asymmetries may arise and persist under goodwill as well as awareness advertising. The basis for a strategic advantage, however, differs greatly in the two models of advertising. We show that tighter regulation or an outright ban of advertising may have anticompetitive effects and discuss how firms use advertising to deter and accommodate entry and induce exit in a dynamic setting.     

Political Interference and Stock Price Consequences of Local Bias

Politics can interfere with capital markets. We show that political interference is a necessary condition for local bias in the stock market. We extend the framework of Hong, Kubik and Stein (2008) and find that the inverse relation between market‐to‐book ratios and the ratio of the aggregate book value of firms to the aggregate risk tolerance of investors in a state (RATIO) is only prevalent among firms located in areas where politics has substantial influence on local markets. Our results indicate that the impact of politically induced local bias is primarily demand driven and stronger among firms that are less visible.     

Financing Decisions along a Firm’s Life‐cycle: Debt as a Commitment Device

We analyse the life‐cycle patterns of a firm’s financing decisions and their interaction with future growth and development decisions. We derive different financing sequences which we link to existing empirical research as well as derive new testable hypotheses regarding differences in firms’ financing decisions to project, firm, market and country characteristics. We provide a rationale for the importance of (external) start‐up debt financing as observed in recent empirical studies. Furthermore, we argue that equity financing at both development stages is more likely for closely‐held firms and in countries in which entrepreneurs face high stigmatisation costs.     

Dynamic Olley‐Pakes productivity decomposition with entry and exit

We propose an extension of the Olley and Pakes ( 1996 ) productivity decomposition that accounts for the contributions of surviving, entering, and exiting firms to aggregate productivity changes. We argue that the other decompositions that break down aggregate productivity changes into similar components introduce some biases in the measurement of the contributions of entry and exit. We apply our proposed decomposition to Slovenian manufacturing data and contrast our results with those of other decompositions. We find that, over a five‐year period, the measurement bias associated with entry and exit is substantial, accounting for up to 10 percentage points of aggregate productivity growth.     

Product market competition and cost stickiness

Extant literature on cost stickiness has focused on how firm-specific characteristics affect the asymmetric cost behavior. In this paper, we explore how a firm’s operating environment affects the firm’s cost stickiness. Specifically, we examine the effect of product market competition on cost stickiness since a firm’s investment and cost retention decisions partly depend on how the firm interacts with its rival firms in the product markets. Using two firm-level text-based product market competition measures extracted from management disclosures in firms’ 10-K filings (Li et al. in J Account Res 51(2):399–436, 2013; Hoberg and Phillips in Rev Financ Stud 23(10):3773–3811, 2010; J Polit Econ, 2015), we find strong evidence consistent with cost asymmetry increasing in competition after controlling for known economic determinants of cost stickiness. In additional analyses, we also find that the effect of product market competition on the degree of cost stickiness increases in firms’ financial strength, likely because management in financially stronger firms has more resources for investment expenditures in spite of a sales fall. We also find that cost stickiness is increasing in competition if management is optimistic about future demand, whereas competition is not associated with cost asymmetry if management is pessimistic about future demand. Finally, we find that the relationship between competition and cost stickiness, although statistically insignificant at conventional levels, is more pronounced for single-segment firms relative to multi-segment firms.     

Real Options, Product Market Competition, and Asset Returns

We study how competition in the product market affects the link between firms' real investment decisions and their asset return dynamics. In our model, assets in place and growth options have different sensitivities to market wide uncertainty. The strategic behavior of market participants influences the relative importance of these components of firm value. We show that the relationship between the degree of competition and assets' expected rates of return varies with product market demand. When demand is low, firms in more competitive industries earn higher returns, whereas when demand is high firms in more concentrated industries earn higher returns.     

Market Feedback,Investment Constraints,and Managerial Behavior

This paper examines the joint role of market feedback and investment constraints on managerial behavior. Using a sample of UK fixed price initial public offerings, we show that underperformance of share returns at the IPO significantly affects managerial investment decisions in the period after the offering. Firms with better investment opportunities and proportionately lower fixed (higher intangible) assets are more sensitive to negative market feedback. Over the longer term, the more responsive firms perform significantly better than their non‐responsive counterparts. The findings contribute to the debate on the informational advantage of managers over investors and present strong evidence that the market, on aggregate, can provide a superior assessment of a firm's opportunities. Managers who are able to respond to negative market feedback can significantly improve their firm's future prospects.     

Acquisitions and funding conditions

We find evidence that aggregate funding conditions play an instrumental role in mergers and acquisitions (M&A). Funding conditions impact the benefits, participants and the number of deals transacted and this impact extends well beyond merger waves. Specifically, when aggregate funding conditions are favorable, the merger market is especially active and small, financially-constrained firms participate heavily. These same firms, however, are largely absent from the deal market when funding conditions are tight. Furthermore, investors view deals during favorable environments as relatively attractive, particularly if the deals are initiated by small bidders. In contrast, deals transacted by large firms during easy-money periods are viewed as value-destroying. We also document that these value-destroying deals are particularly prevalent among large bidders with significant potential for agency costs. Overall, our results suggest that aggregate funding conditions do not merely cause bidders to adjust the scope of their investment decisions consistent with capital rationing, but rather, the changing state of aggregate funding appears to significantly determine the size and composition of the M&A potential bidder pool.     

Investment risk allocation and the venture capital exit market: Evidence from early stage investing

This study provides evidence on how venture capitalists’ (VCs’) allocations of capital to riskier investments, as measured by the proportion of early versus late-stage investment in an industry, are linked to exit market conditions. Prior research has primarily focused on how VCs adjust aggregate investment to public equity market conditions. We develop a more inclusive measure of exit market conditions that accounts for recent secular changes that have affected the industry return structure, specifically, the sharp rise in the number of failures and M&A relative to IPO exits. We show that the dollars gained relative to dollars lost in recent exits and failures are significantly positively related to VCs’ allocations to early-stage companies over the period 1990–2008. The changes in allocations are large enough to have an effect on the availability of funding for early stage companies. In sum, our evidence shows that exit market conditions have a significant and economically meaningful influence on VCs’ allocations to riskier investments.     

The Value of Crowdfunding: An Explanation Based on Demand Uncertainty and Comparison with Venture Capital

This article notes that an advantage of crowdfunding is in its ability to help start-up firms acquire more accurate market demand information regarding new products when compared with venture capital (VC). The whole market of a given product can be conceptualized as being segmented into several, small local markets. VC has a comprehensive knowledge of local markets in general but is prone to noisy aggregate demand information as a result. While crowdfunding investors have intimate knowledge regarding local demand information in their respective locales, they lack knowledge in other local markets. We show that under certain conditions, crowdfunding can provide more accurate demand information and therefore can generate better incentives to entrepreneurs while improving product quality and helping entrepreneurs make correct decisions on whether or not to launch a new product. Therefore, the wisdom of the crowd can be more valuable than the wisdom of the expert.     

Employment protection, firm selection, and growth

How do firing costs affect aggregate productivity growth? To address this question, a model of endogenous growth through selection and imitation is developed. It is consistent with recent evidence on firm dynamics and on the importance of reallocation for productivity growth. In the model, growth is driven by selection among heterogeneous incumbent firms and is sustained as entrants imitate the best incumbents. In this framework, firing costs not only induce misallocation of labor, but also affect growth by affecting firms’ exit decisions. Importantly, charging firing costs only to continuing firms raises growth by promoting selection. Also charging them to exiting firms is akin to an exit tax, hampers selection, and reduces growth—by 0.1 percentage points in a calibrated version of the model. With job turnover very similar in the two settings, this implies that the treatment of exiting firms matters for growth. In addition, the impact on growth rates is larger in sectors where firms face larger idiosyncratic shocks, as in services. This fits evidence that recent EU-U.S. growth rate differences are largest in these sectors and implies that firing costs can play a role here.     

An empirical re-examination of the dividend–investment relation

Modigliani and Miller show that, in perfect capital markets, the optimal investment decisions of a firm are not affected by how these investments are financed. Miller and Modigliani further imply that, under the assumption of perfect capital markets, a firm's investment decisions are not affected by its dividend decisions, although dividend decisions may or may not be influenced by investment decisions. Fama and Miller label this result the separation principle. Most recent studies of the separation principle that take into account the existence of market imperfections report sharply contradictory results. This paper tests for linear and nonlinear causality between dividends and investments using both firm-specific and aggregate data for a sample of 417 firms over the 1962 to 2004 period. In general, linear causality tests support the separation principle, whereas nonlinear causality test results contradict the separation principle by revealing strong bi-directional linkages between dividends and investments.     

Market opportunities and owner identity: Are family firms different?

We test the hypothesis that ownership of a firm does not affect the firm's ability to seize market opportunities once decisions about productive structure are taken into account. By grouping firms in size clusters having a similar distance between the actual and the optimal size, we assess how the sensitivity of a firm's sales to market demand changes in response to differences in the owner's identity. We use data from a panel of 4696 continental western European firms over the period 1995–2010 and Eurostat 3-digit sectoral data on firm size distribution. Empirical evidence rejects the hypothesis of ownership irrelevance: family firms are less sensitive to market demand than other firms, in particular when the actual size of the firm is larger than optimal and in the case of both founder- and heir-run family firms.     

Signaling in the Internet craze of initial public offerings

We explain the clustering of underpricing in initial public offerings (IPOs). The model features an industry with aggregate demand uncertainty and asymmetric information about firms' quality. In the IPO market, firms can signal quality by underpricing or under-issuing new shares. Expected aggregate demand for the industry's products increases with the publicity that the industry creates through IPO underpricing. We show that asymmetric information and expectations on aggregate product demand interact with each other to generate multiple equilibria. Underpriced IPOs cluster in one equilibrium but not in the other. We use these results to explain why the clustering often occurs in particular industries, is short-lived, and is sensitive to economic conditions.     

Financial flexibility: Do firms prepare for recession?

We analyze how firms manage their financial flexibility conditional on the expected probability of recession. Using an ex ante measure of future recession, we find that, in the aggregate, firms do not appear to prepare. However, a closer analysis reveals a more nuanced relation. The lack of preparation in aggregate is driven by firms that may be unable to prepare: financially constrained and cash poor firms. We find some evidence that firms able to prepare, unconstrained and cash rich firms, may prepare for future recessions.     

A theory of growth and volatility at the aggregate and firm level

We present an endogenous growth model that explains the evolution of the first and second moments of productivity growth at the aggregate and firm level during the post-war period. Growth is driven by the development of both (i) idiosyncratic R&D innovations and (ii) general innovations that can be freely adopted by many firms. Firm-level volatility is affected primarily by the Schumpeterian dynamics associated with the development of R&D innovations. The variance of aggregate productivity growth is driven by the arrival rate of general innovations. Ceteris paribus, the share of resources spent on development of general innovations increases with the stability of the market share of the industry leader. As market shares become less persistent, the model predicts an endogenous shift in the allocation of resources from the development of general innovations to the development of R&D innovations. This results in an increase in R&D, an increase in firm-level volatility, and a decline in aggregate volatility. The effect on productivity growth is ambiguous.On the empirical side, this paper presents new cross-country evidence that R&D subsidies are not significantly associated with higher growth but are associated with lower aggregate volatility. It also documents an upward trend in the instability of market shares, a positive association between firm volatility and R&D spending, and a negative association across sectors between R&D and how correlated the sector is with the rest of the economy.     

Rational IPO Waves

We argue that the number of firms going public changes over time in response to time variation in market conditions. We develop a model of optimal initial public offering (IPO) timing in which IPO waves are caused by declines in expected market return, increases in expected aggregate profitability, or increases in prior uncertainty about the average future profitability of IPOs. We test and find support for the model's empirical predictions. For example, we find that IPO waves tend to be preceded by high market returns and followed by low market returns.     

Capital Share Dynamics When Firms Insure Workers

Although the aggregate capital share of U.S. firms has increased, capital share at the firm‐level has decreased. This divergence is due to mega‐firms that produce a larger output share without a proportionate increase in labor compensation. We develop a model in which firms insure workers against firm‐specific shocks, with more productive firms allocating more rents to shareholders, while less productive firms endogenously exit. Increasing firm‐level risk delays exit and increases the measure of mega‐firms, raising (lowering) the aggregate (average) capital share. An increase in the level of rents magnifies this effect. We present evidence that supports this mechanism.
