It Ain't Over 'Til It's Over”. Accounting and the COVID-19 pandemic. Insight gaps and agenda for future research

The outbreak of the COVID-19 pandemic has imposed numerous constraints, caused enormous disruptions and has been associated with more than 6.5 million deaths worldwide (as of 19th October 2022). It also raised opportunities to imagine a new environment. Accounting academics have been involved in studying and thinking about the questions this poses for research and practice. Accounting scholars have explored the responses to the pandemic crisis and provided important insights about its impact. However, there is relatively little research into how accounting scholarship has contributed collectively to understanding and challenging the e!ect of the COVID-19 crisis. As accounting scholarship had time to grow, this seems an opportune time to offer a preliminary assessment and an early indication of the emergent themes and challenges. This research also aims to bring together and reconcile insights from an understandably fragmented literature and propose an agenda for future research.

Measuring Markups with Revenue Data

Standard production-based markup estimators are biased and inconsistent when output prices are unobserved. Absent additional assumptions, researchers cannot disentangle whether firms have higher revenues because of higher productivity or higher markups. We propose a method that generates unbiased and consistent estimates by modifying physical productivity process assumptions into revenue productivity process assumptions, and by flexibly modeling markups as a specified function of observables and fixed effects. Our method builds on past work designed to estimate production functions in competitive environments. Our suggested two-step estimator is simple in concept and implementation, requiring only common regression techniques.

Inequality of opportunity in South Asia

Building on earlier work by political philosophers, economists have recently sought to define a concept of equity that accommodates the fairness of reward to individual responsibility and effort, while allowing for the existence of some inequalities which are unfair and should be compensated. This paper – commissioned as a chapter for the Oxford Handbook of Well Being and Public Policy – provides a critical review of the economic literature on equality and inequality of opportunity. A simple 'canonical model' of equal opportunity is proposed, and used to explore the two fundamental concepts in this (relatively) new theory of social justice: the principles of compensation and reward. Ex-ante and ex-post versions of the compensation principle are presented, and the tensions between them are discussed. Different approaches to the measurement of inequality of opportunity – and empirical applications – are reviewed, and implications for the measurement of poverty and of the rate of economic development are discussed.

Future Work Self: insights and future directions

Major nontraditional career perspectives highlight the need for greater self-directedness in one’s career. As individuals assume responsibility and agency for their career decisions, they are supposed to develop a clear idea of who they want to be in their future. Scholars have underlined the role of future work self – a positive representation of the future self in the work domain - in motivating proactive behaviors to strive for the envisioned future. However, few studies have examined theory-based mediators and conditions that influence this relationship. Drawing from control theory, we present an empirical paper testing the mediating role of career self-exploration, and provide insights on the role of future work self salience and elaboration in predicting proactive career behaviors. Moreover, we outline a research agenda based on a comprehensive overview of the future self domain.

Do Brother Correlations in Occupational Status and Income Overlap? Evidence on the Common Family Origins of Attainment in the United States and Denmark

We examine whether brother similarities in occupational status are rooted in the same underlying family characteristics that affect brother similarities in income. We extend previous research using sibling correlations as an omnibus measure of total family background impact on a given outcome by directly quantifying how sibling correlations in occupational status and income overlap. We apply a novel variance components model to data from Denmark and the United States, two countries known to follow a contradictory pattern: While income mobility is much lower in the United States, occupational mobility is virtually similar. Apart from confirming this pattern, we find a substantial overlap, around 70 percent, in brother similarities in income and occupational status in both countries. Conventional family background variables account for only about one-fifth of this overlap in each country, suggesting that shared family origins of attainment in these two domains are constituted by largely unknown family characteristics. We discuss what these characteristics might be.

Robots on Sale: The Effect of Investment Promotion on Robot Adoption and Employment

We study the role of an investment promotion policy in adopting industrial robots and firm performances, notably employment. Combining the policy variation in the Tax Credit for Promoting Productivity-Enhancing Equipment Investment (TC-PPEI) in Japan and a newly collected Japanese firm-level longitudinal data on robot adoption, we find that the firms eligible for the TC-PPEI increased the adoption of robots. Our event-study analysis reveals that when firms adopt robots, they do not decrease the total number of workers but significantly increase it after 1-3 years of adoption event as well as sales. Our results suggest that adopting robots can be employment creating instead of destroying at the firm level.

Environmental Risk Perception and Green Bond Pricing: Evidence from Natural Disasters

Green bonds are debt securities whose proceeds are used for environmentally friendly purposes. It is a fast growing market with more than$500bn capital raised in 2021. We study how investors’ environmental risk perception affects green bond pricing. To assess causality, we focus on exogenous shocks induced by the occurrence of natural disasters. We use a sample of 781 green bond emissions matched with comparable brown bonds. The evidence shows that the price of green bonds increases relative to that of comparable brown bonds following a natural disaster, both at bond issuance and in the secondary market. Also, the severity of the disaster explains the magnitude of the price increase, as disasters affecting a larger number of people result in a greater increase in price. This price increase is temporary, as green bond prices revert to pre-disaster levels after a few months. Overall, the evidence is consistent with a temporary overreaction by investors in terms of perceived environmental risk.

Coarse Correlated Equilibria

Correlated equilibria (Aumann 1974) are a well-known solution concept for N-player games.`Coarse correlated equilibria' (Young 2004), also known as the `Hannan set' (Hart and MasColell 2001), were introduced by Moulin and Vial (1978). I will discuss their relevance for evolution (replicator dynamics) and learning (fictitious play) in games.

Managing Small Business In Times Of Uncertainty: Notes And Reflections On Business Resilience And Sustainability

For business entities ‘resilience’ means survival and continuity; and 'sustainability' means adding value to the existing assets (including the brand) and avoiding value erosion, cost and burden for the future. The strategic imperative of any business entity is to create market value and, at the same time, to ensure the continuity of the firm and its stakeholders’ network. Business organizations may create, temporarily, some market value thanks to good stakeholder network coordination, efficient supply chain management and productivity of each unit involved in the business process. But to ensure continuity with value they need to have full support from their socio-economic context where the stakeholders are based and where they operate. Sustainability-centred management model may contribute to the quality of local socio-economic context which, in turn, would ensure moral legitimacy and support for the enterprises from the society at large.

Mediterranean Capitalism Revisited

By examining and comparing such components as welfare, education and innovation policies, cultural dimensions, and labor market regulation, the contribution attends to both commonalities and divergences between the four Southern European countries, identifying the main reasons behind the poor performance of their economies and slow recovery from the Great Recession of 2007–2008. It also sheds light on the process of diversification among the four countries and addresses whether it did and still does make sense to speak of a uniquely Mediterranean model of capitalism.

The Marginal Propensity to Consume in a Depressed Economy: Estimates from a Lottery and Administrative Data

We use the quasi-experimental setting of a tax lottery together with administrative and survey data to provide reported-preference and revealed-preference estimates of the marginal propensity to consumer (MPC). In the depressed economic environment of Greece, providing scarce opportunities for consumer credit, we uncover significantly higher MPCs than previous literature. There is significant heterogeneity in MPC, and we link it to observable household characteristics.

Social Norms - Determinants, Incompatibilities, Effects

Institutional Economics can be considered a huge success story as today, almost nobody would dispute its main claim that “institutions matter”. Yet, for a long time, social norms and other informal institutions played a minor role at best in this success story. In my talk, I will therefore focus on social norms and discuss why they could be so important for societal development, on the necessary compatibility between formal and informal institutions and on why so many informal institutions seem to eschew attempts at deliberate change. Some of these insights have direct policy implications.

Gatekeeping in Anonymous Marketplaces: An Empirical Investigation of Online Black Markets

Digital marketplaces are transaction platforms that allow people and organizations to buy, sell, or access a variety of goods and services. A major problem in managing digital marketplaces is gatekeeping, as platforms must be open for trading opportunities while being protected from deviant behavior. In this study, we investigate gatekeeping in the context of Online Black Markets (OBM). OBMs are digital transaction platforms where anonymous buyers and vendors exchange illegal products and services with highly conflicting goals and in the absence of formal rules and regulatory bodies. Building upon the investigation of this extreme case, we conducted mixed-method research to identify gatekeeping mechanisms that influence platform survival. Our findings advance the understanding of platform openness and the growth and survival of digital transaction platforms. Keywords: openness, gatekeeping, digital platforms, control mechanisms, darknet, crypto markets, survival.

Organizational models in healthcare: new approaches to meet the needs of chronic patients

The intrinsic complexity of healthcare organizations is widely testified in literature (Dohorty et al., 2022). The demand of healthcare services in developed countries has changed deeply. The population is ageing and is therefore characterized by multi-pathological chronic conditions. Moreover, patients are more informed about their rights and, consequently, expectations from the public health care system have risen considerably. On the other hand, however, there exist dramatic financial pressures which require healthcare organizations to provide more and better services with equal (if not decreasing) resources (Gabutti et al, 2017). Therefore it is clear that many features of healthcare systems are doomed to change if the whole system is to remain of high quality and sustainable in time (Lega and DePietro, 2005). In this seminar we will explore the main pillars of change in Western healthcare systems and their emerging organizational models, both referred to hospitals and to primary care settings (Petrakaki et al, 2010). We will discuss barriers and enabling factors to their full implementation, so to foster deep awareness of the main managerial priorities within this complex and articulate sector (Jacobs et al, 2015).

e-Globalization and Trade Agreements

The global success of online search engines and social media is due in part to their free access and high level of quality. However, these features are supported by a business model that exploits user data to provide targeted advertising services to third parties. This raises questions about the potential impacts of this business model on global and national welfare. This study aims to examine how a global monopoly platform might balance privacy and service quality in light of these concerns. Results indicate that when a platform operates a free service model, it tends to overuse personal information and under-invest in quality compared to a global planner. However, global welfare can be improved through policy interventions such as enhanced privacy protection. Furthermore, this study suggests that when privacy policies are set at the national level, large countries tend to align with the global interest, thanks to a "Brussels effect" where a global monopoly platform will improve privacy protection across all its markets in response to a policy change in one country. This implies that the need for international trade agreements covering privacy protection is reduced. However, we find that the use of ad tech taxes is an area where international cooperation is needed due to the potential negative impacts on other countries.

Gender mix and team performance: Differences between exogenously and endogenously formed teams

We conduct a randomized controlled trial to study how the self-selection of individuals into teams changes the impact of a team’s gender composition on gender preferences, team performance, and individual performance. We randomly divide a sample of high-performing high school students into two groups: we assign students in one group to teams of varying gender composition, and we allow the students in the other group to form teams freely. We find that the latter choose more male-predominant teams than the former, and if self-selected into gender-biased teams, students prefer even more gender-biased teams ex-post. We also find that female-predominant teams underperform other types of teams when we form teams exogenously, but these differences disappear when students form teams endogenously.

Understanding spatial agglomeration: increasing returns, land, and transportation costs

Economic activities are concentrated on a small share of inhabitable land. In our view, this agglomeration is the outcome of a trade-o§ between increasing returns and transportation cost, which capitalizes into land rents. Our second baseline idea is that Tiebout-like sorting provides a general framework to handle a large array of spatial problems in spatial economics. Cities have high housing prices because they are productive and o§er high levels of amenities and public goods. Both production and amenity e§ects capitalize in the land rent at a particular location. Through the process of bidding for land, spatial sorting is the involuntary consequence of a myriad of individual decisions made by agents which pursue their own interest
