Corporate governance is fundamental to well-run organisations. Accordingly, it is associated with the positive performance of corporations and international best practices. It is the blueprint that helps shareholders scope their activities and engagement within a company, including the role and structures of the Board of Directors (BoD). It is against this backdrop that the BoD is the nexus between executive leadership and corporate governance, a hallmark of an effective functioning corporation and the affirming of an integrative approach. Thus, good corporate governance is arguably an important tool in curbing corporate malfeasance and limiting scandals in corporations. Conversely, poor cor..

Larger firms feature i) longer hours worked, ii) higher wages, and iii) smaller (larger) wage penalties for working long (short) hours. We reconcile these patterns in a general equilibrium model, which features the endogenous interaction of hours, wages, and firm size. In the model, workers willing to work longer hours sort into larger firms that offer a wage premium. Complementarities in hours worked generate wage penalties that increase with the distance from the average firm hours. We use the model to argue about the importance of the interaction between hours, wages, and firm size on inequality.

We revisit the estimation of industry wage differentials using linked employer-employee data from the U.S. LEHD program. Building on recent advances in the measurement of employer wage premiums, we define the industry wage effect as the employment-weighted average workplace premium in that industry. We show that cross-sectional estimates of industry differentials overstate the pay premiums due to unmeasured worker heterogeneity. Conversely, estimates based on industry movers understate the true premiums, due to unmeasured heterogeneity in pay premiums within industries. Industry movers who switch to higher-premium industries tend to leave firms in the origin sector that pay above-average pre..

In line with Keynes’ intuition, volatility in the stock market and in real economic activity are linked by expectations of long term profits. We show that analysts’ optimism about the long term earnings growth of S&P 500 firms is associated with a near term boom in major US financial markets, real investment, and other business cycle indicators. The same optimism however predicts disappointing earnings growth and a contraction in financial markets and real activity one to two years later. Overreaction of measured long term profit expectations emerges as a promising mechanism for reconciling Shiller’s excess volatility puzzle with the business cycle.

I present a political economic theory, explaining bailouts for failing firms in the presence of non-voters (foreigners). The governing politician uses the bailout as a tool to sway voters for maximizing re-election chances. Bailouts partially leak to foreigners at the firm and are also financed by tax-paying foreigners outside the firm. I show, larger failing firms are granted larger bailouts even if the additional size is due to having more foreign stakeholders (``too-big-to-fail- lookalike''). Yet, among equally sized firms, the firm with more voting-stakeholders receives the larger bailout, contradicting social optimality. Besides firm size, also voting rights cause bailouts.

Despite the rising interest for backshoring strategies by mass media, policy makers and public debates, academic research on the topic is relatively recent and still characterised by significant research gaps. Empirical evidence is scarce and often anecdotal, with a lack of studies focusing on specific industries and small-sized firms. Theoretical explanations are also fragmented with many unanswered questions. In particular, much of the existing literature has explored backshoring as a stand-alone phenomenon, independently from other production location strategies. In an attempt to fill these research gaps, we rely upon data from an original survey with around 700 firms from the UK textile ..

This paper provides evidence on the effects of digitalisation on the labour market in Slovenia using a unique dataset of Slovenian workers and firms for the years 2016 to 2020. Results show that at the firm level, digitalisation – measured in terms of ICT investment, is associated with positive and statistically significant effects on employment. However, job growth is not evenly distributed: High-skilled workers and younger workers benefit the most from employment gains, whereas there is little to no employment increases for low- and medium-skilled workers and older workers aged 50 or more. Furthermore, employment effects from digitalisation are strongest for private manufacturing firms. ..

This paper provides evidence on the impact of digitalisation on productivity in Slovenia during the COVID-19 crisis. The pandemic affected overall labour productivity negatively. Nonetheless, results show that firms that were more ICT-intensive before the pandemic experienced a smaller decline in their labour productivity growth compared to their less ICT-intensive peers in the same 2-digit level sector. This resilience effect was strongest for firms that are integrated in global value chains. A second finding is that COVID-19 resulted in productivity-enhancing reallocation of labour to ICT-intensive firms, reflecting that these firms registered higher employment growth relative to their les..

Based on firm level data in the French manufacturing sector, we find that firms adapt quickly, strongly and through multiple channels to energy shocks, even though electricity and gas bills represent a very small share of their total costs. Over the period 1996-2019, faced with an idiosyncratic energy price increase, firms reduce their energy demand, improve their energy efficiency, increase intermediate inputs imports and optimize energy use across plants. Firms are also able to pass-through the cost shock fully on their export prices. Their production, exports and employment fall. A consequence of these multiple adjustment mechanisms is that the fall in profits is either non-significant, s..

The consequences of the pandemic for potential output will partly hinge on its impact on productivity-enhancing reallocation. While recessions can accelerate this process, the more ‘random’ nature of the COVID-19 shock coupled with policy responses that prioritised preservation could disrupt productivity-enhancing reallocation. Our analysis based on novel high-frequency employment data for Australia shows that labour reallocation (and firm exit) remained connected to firm productivity over 2020 and 2021. However, outside of the initial acute phase of the shock the relationship weakened significantly compared to history. Australia’s job retention scheme (JobKeeper) initial..

Within modern economies firms are embedded in often complex supply chains, creating strong interdependencies between firms. But what happens when these supply chains are disrupted, what changes does this bring about? We answer these questions, focusing on what happens when connections between companies exogenously break because of the unexpected death of the CEO within one of the firms. We rely on detailed data from the TSR which provides firm-level measures of start and exit dates of CEOs along with buyer-supplier linkages. This data is matched to detailed statistics on Japanese firms which enables us to identify the effects of such leadership changes on supplier networks and subsequent per..

Productivity disparities in the European regions tend to persist. In order to understand the underlying sources of this phenomenon we assess the importance of science and regional innovation modes on firms’ productivity growth on a sample of 150, 712 firms across 161 NUTSII European regions, over the period 2012-2017. We find that science is a major source of firms’ productivity growth, and it has been particularly important to firms located in Southern Europe and, to less extent, in Eastern EU regions, indicating that a science-push convergence process is at work in the EU peripheral regions. Our findings also show that the fast-growing productivity firms are those who benefit..

R&D tax credits, by stimulating private sector innovation, can play a key role in promoting employment and firm performance. This paper examines the program impact on the trajectory of firms in terms of technology adoption, firm performance and workforce composition, and the extent to which it depends on the size of the targeted firms. It uses rich longitudinal micro-data on innovation, firms and their workers. Combining matching with a staggered adoption differences-in-differences, we show that tax credits increase investment in R&D-related activities while funds are being received, but not thereafter. Productivity and efficiency (but not employment) increase in large firms. These effects a..

We study the costs and benefits of selling data to a competitor. Although selling all consumers' data may decrease total firm profits, there exist other selling mechanisms -- in which only some consumers' data is sold -- that render both firms better off. We identify the profit-maximizing mechanism, and show that the benefit to firms comes at a cost to consumers. We then construct Pareto-improving mechanisms, in which each consumers' welfare, as well as both firms' profits, increase. Finally, we show that consumer opt-in can serve as an instrument to induce firms to choose a Pareto-improving mechanism over a profit-maximizing one.

We use the U.S. patent data merged with firm-level datasets to establish new facts about the role of mega firms in generating “novel patents”—innovations that introduce new combinations of technology components for the first time. While the importance of mega firms in novel patents had been declining until about 2000, it has strongly rebounded since then. The timing of this turnaround coincided with the ascendance of firms that newly became mega firms in the 2000s, and a shift in the technological contents, characterized by increasing integration of Information and Communication Technology (ICT) and non-ICT components. Mega firms also generate a disproportionately large number of “hi..

Using administrative data on health insurance, retirement, and leave benefits, we find within-firm variation accounts for a dramatically lower percentage of total variation in benefits than in wages. We also document sharply higher between-firm variation in nonwage benefits than in wages. We argue that this pattern can be a consequence of nondiscrimination regulations, fairness concerns, and the high administrative burden of managing too many or complex plans. Consistent with this mechanism, we show that the presence of high-wage workers in unrelated divisions of a firm as well as workers hired in high-benefit local labor markets positively predicts their colleagues’ benefits, controlling ..

The global financial crisis that burst in 2008 adversely affected business performance in many countries, especially in Europe. However, the impact of the crisis on entrepreneurship and business dynamics differed amongst countries, depending on their businesses resilience, the policies implemented, but also their predominant productive structure. The magnitude and length of the Greek depression have no precedent among modern middle and high-income economies. Still, to date, there is no systematic analysis of the impact of the crisis on entrepreneurship and business dynamism. This study attempts to fill this gap by examining individual firm, sectoral and regional level characteristics that mi..

Firms can voluntarily create independent firms to implement their technologically distant innovations and capture their value through capital markets. We argue that when firms repeatedly compete to make innovations, there is inefficient external implementation of innovations and “excessive†creation of such firms. This inefficiency is most exacerbated in the early stages of an industry, when the number of firms is still limited.

We develop a framework to analyse stability of cartels in differentiated Cournot oligopolies when multiple cartels may exist in the market. The consideration of formation of multiple cartels is in direct contrast to the existing literature which assumes, without further justification, that at most a single cartel may be formed, and we show that this consideration has markedly different implications for cartel stability. We define a cartel configuration to be stable if: (i) a firm in a cartel does not find it more profitable to leave the cartel and operate independently, (ii) a firm that operates independently does not find it more profitable to join an existing cartel, (iii) a firm in a cart..

We use China’s growth experience as a laboratory to study how reductions in entry barrier contribute to economic growth by inducing a more competitive market structure. The removal of entry restrictions on private firms in the late 1990s and early 2000s made the Chinese economy more competitive and dynamic, propelling the growth acceleration from the early 1990s to late 2000s. We develop a model of endogenous productivity and market structure with heterogeneous firms and frictional entry and calibrate it to Chinese manufacturing from 2004-7. We show about 25% of the productivity growth in 2004-7 is contributed by the reduction of entry barriers during the reforms in the previous decade. Wh..

R&D decision of a firm involves various sources of incomplete information. The present paper introduces incomplete information about the success probability of R&D in a model of two firms interacting in R&D and production and discusses the choice between cooperative and non-cooperative research. We consider research joint venture as the form of R&D cooperation. While the choice depends on the constellation of parameters, the following results are derived, in general. First, the high type firm always has a larger incentive for both cooperative and non-cooperative R&D compared to the low type firm. Second, if the low type firm goes for non-cooperative research, then the high type firm must go ..

This paper studies the role of credit constraints in accounting for the dynamics of firm exit during the Great Recession. We present novel firm-level evidence on the role of credit constraints on exit behavior during the Great Recession. Firms in financial distress, with tighter access to credit, are more likely to default than firms with more access to credit. This difference widened substantially in the Great Recession while, in contrast, default rates did not vary much by size, age, or productivity. We identify conditions under which standard models of firms subject to financial frictions can be consistent with these facts.

Using data on both buyer-supplier and owner-subsidiary links between Japanese firms, we characterize the interconnection between production and ownership networks. In the cross-section, we find that the majority of the owner-subsidiary links are also buyer-supplier links, thus highlighting the role of goods or services transactions in vertical integration. In addition, we find that firms are more likely to engage with buyers/suppliers that have already been used by related parties, thereby suggesting an indirect benefit of integration. Finally, we show evidence that more capable firms are more likely to integrate buyers/suppliers conditional on the number of buyers/suppliers. As firms grow, ..

Entry and exit of firms and changes in employment and productivity are expected to bring about an increase in national economic growth and productivity. However, there is concern that the increasing importance of digital technology with its network externalities will make it more difficult for new firms to grow and overcome the advantages of incumbents, widening the productivity gap among firms. On the other hand, in industries where new technologies, such as digital technologies, are advancing rapidly, it is possible that there will be increasing activity of new firms entering and exiting the market. In this paper, we measure the entry and exit, job creation and destruction, and inter-firm ..

This paper proposes a novel method to estimate productivity and quality at the firm-product level, together with transformation function and demand parameters. The method relies on firm optimization conditions to obtain a one-to-one mapping between observed data and unobserved productivity and quality. It has the advantage of allowing for heterogeneous unobserved intermediate input prices and scalability to handle a large number of products, without imputing firm-product input shares or relying on productivity evolution. We apply this method to a set of Mexican manufacturing industries. We find that multi-product firms’ better performing products have both higher productivity and higher qu..

We identify the effects of corporate income tax shocks on key US macroeconomic aggregates. In response to a corporate income tax cut, we find that: (i) labor productivity increases; (ii) entry increases with delay; (iii) exit increases; (iv) total labor increases by more than production labor. To rationalize these empirical findings, we build a New Keynesian model with idiosyncratic firm productivity, and entry and exit. Our model features productivity gains due to selection and cleansing along the entry and exit margins. Models with homogeneous firms fail to account for the selection and cleansing process and produce counterfactual results.

We study the shifts in U.S. firms' workforce composition and organization associated with the use of AI technologies. To do so, we leverage a unique combination of worker resume and job postings datasets to measure firm-level AI investments and workforce composition variables, such as educational attainment, specialization, and hierarchy. We document that firms with higher initial shares of highly-educated workers and STEM workers invest more in AI. As firms invest in AI, they tend to transition to more educated workforces, with higher shares of workers with undergraduate and graduate degrees, and more specialization in STEM fields and IT skills. Furthermore, AI investments are associated wi..

Heterogeneous firm models are ubiquitous in modern macroeconomics. We revisit a central feature of these models: the idiosyncratic shock process faced by firms. Using a large representative firm-level dataset, we document nonparametrically that the common assumption, a Gaussian AR(1) shock process, is at odds in important ways with observed fat-tailed firm dynamics. We embed these findings within a standard quantitative general equilibrium heterogeneous firm dynamics model and show that the nature of firm-level shocks has a sizable quantitative effect on the economy’s responsiveness to aggregate shifts.

We introduce a new measure of own-price inflation uncertainty using firm-level data from a large and representative survey of UK businesses. Inflation uncertainty increased significantly from the start of 2021 and reached a peak in the second half of 2022, even as a similar measure of sales uncertainty declined. We also find large cross-sectional differences in inflation uncertainty, with uncertainty particularly elevated for smaller firms and those in the goods sector. Finally, we show that firms which are more uncertain about their own price expectations experience higher forecast errors 12 months later. These findings suggest that studying inflation uncertainty at the firm level may be an..
