Heterogeneous Taxes and Limited Risk Sharing: Evidence from Municipal Bonds

Author
Babina, Tania, Chotibhak Jotikasthira, Christian Lundblad, and Tarun Ramadorai

We evaluate the impacts of tax policy on asset returns using the U.S. municipal bond market. In theory, tax-induced ownership segmentation limits risk-sharing, creating downward-sloping regions of the aggregate demand curve for the asset. In the data, cross-state variation in tax privilege policies predicts differences in in-state ownership of local municipal bonds; the policies create incentives for concentrated local ownership. High tax privilege states have muni-bond yields that are more sensitive to variations in supply and local idiosyncratic risk.

How Quantifying the Shape of Stories Predicts Their Success

Author
Toubia, Olivier, Jonah Berger, and Jehoshua Eliashberg

Narratives, and other forms of discourse, are powerful vehicles for informing, entertaining, and making sense of the world. But while everyday language often describes discourse as moving quickly or slowly, covering a lot of ground, or going in circles, little work has actually quantified such movements or examined whether they are beneficial.

How Research Affects Policy: Experimental Evidence from 2,150 Brazilian Municipalities

Author
Hjort, Jonas, Diana Moreira, Gautam Rao, and Juan Francisco Santini
Can research findings change political leaders' beliefs and policies? We use experiments with 2,150 Brazilian municipalities to measure mayors' demand for and response to research information. In one experiment, we find that mayors are willing to pay to learn the results of evaluation studies, and update their beliefs when informed of the findings. They value larger-sample studies more, while not distinguishing between studies in rich and poor countries.

Intentions for Doing Good Matter for Doing Well: The Negative Effects of Prosocial Incentives

Author
Cassar, Lea and Stephan Meier
Prosocial incentives and Corporate Social Responsibility (CSR) initiatives are seen by many firms as an effective way to motivate workers. Recent empirical results seem to support the expectation that prosocial incentive, e.g., in the form of a charitable donations by the firm, can increase effort and motivation — sometimes even better than monetary incentives. We argue that the benefits crucially depend on the perceived intention of the firm. Workers use prosocial incentives as a signal about the firm's type and if used instrumentally in order to profit the firm, they can backfire.

Interest-Free Financing Promotions Increase Consumers' Demand for Credit for Experiential Goods

Author
Bauer, Johannes, Vicki Morwitz , and Liane Nagengast

This research provides a first investigation into how interest-free financing promotions influence consumer behavior. Five experiments demonstrate that framing an economically equivalent financing offer in a way that makes salient that it is interest-free increases consumers’ demand for credit to finance experiential, but not material goods.

Managerial Style and Attention

Author
Dessein, Wouter and Tano Santos

Is firm behavior mainly driven by its environment or rather by the characteristics of its managers? We develop a cognitive theory of manager fixed effects, where the allocation of managerial attention determines firm behavior. We show that in complex environments, the endogenous allocation of attention exacerbates manager fixed effects. Small differences in managerial expertise then may result in dramatically different firm behavior, as managers devote scarce attention in a way which amplifies initial differences.

The Role of Gender in Pay-What-You-Want Contexts

Author
Santana, Shelle and Vicki Morwitz

This research highlights how gender shapes consumer payments in pay-what-you-want contexts. Four studies involving hypothetical and real payments show that men typically pay less than women in pay-what-you-want settings, due to gender differences in agentic versus communal orientation. Men approach the payment decision with an agentic orientation, and women approach it with a communal orientation. These orientations then shape payment motives and ultimately affect payment behavior.

Moderating Loss Aversion: Loss Aversion Has Moderators but Reports of its Death are Greatly Exaggerated

Author
Mrkva, Kellen, Eric Johnson , Simon Gätcher, and Andreas Herrmann

Loss aversion, the principle that losses impact decision making more than equivalent gains, is a fundamental idea in consumer behavior and decision making, though its existence has recently been called into question. Across five unique samples (Ntotal = 17,720), we tested several moderators of loss aversion, which supported a preference construction account. Across studies, more domain knowledge and experience were associated with lower loss aversion, though people of all knowledge and experience levels were loss averse.

How Does Household Spending Respond to an Epidemic? Consumption During the 2020 COVID-19 Pandemic

Author
Pagel, Michaela

Utilizing transaction-level financial data, we explore how household consumption responded to the onset of the COVID-19 pandemic. As case numbers grew and cities and states enacted shelter-in-place orders, Americans began to radically alter their typical spending across a number of major categories. In the first half of March 2020, individuals increased total spending by over 40% across a wide range of categories.

In the Mood to Consume: Effect of Sunshine on Credit Card Spending

Author
Agarwal, Sumit, Souphala Chomsisengphet, Stephan Meier , and Xin Zou
Using a large, representative sample of high-frequency credit card transactions in the United States, this paper examines the causal effect of sunshine-induced mood on contemporaneous household credit card spending. We document a 0.3 percent increase in credit card spending in response to a one-unit increase in the same-day local abnormal sunshine. The spending response is stronger for consumers with higher credit card debt, lower FICO score, and shorter tenure with the bank.

Sovereign Debt Portfolios, Bond Risks, and the Credibility of Monetary Policy

Author
Du, Wenxin, Carolin Pflueger, and Jesse Schreger

We document that governments whose local currency debt provides them with greater hedging benefits actually borrow more in foreign currency. We introduce two features into a government's debt portfolio choice problem to explain this finding: risk-averse lenders and lack of monetary policy commitment. A government without commitment chooses excessively countercyclical inflation ex post, which leads risk-averse lenders to require a risk premium ex ante.

The Influence of Pensions on Labor Supply

Author
Johnston, Andrew C. and Jonah Rockoff

We cast new light on the influence of pensions on labor supply. To do so, we compare the retention patterns of pension-eligible workers to those of pension-ineligible ones, allowing us to non-parametrically identify the counterfactual in large, administrative data. Pensions exert a retentive force as workers approach the eligibility threshold and apply strong expulsive pressure thereafter (since employees lose pension wealth by remaining employed once eligible).

Does Poverty Negate the Impact of Social Norms on Cheating?

Author
Boonmanunt, Suparee, Agne Kajackaite, and Stephan Meier
Cheating such as corruption and tax evasion is prevalent in the developing world; therefore, many interventions have been undertaken to reduce cheating in developing countries. Although some field evidence shows that poverty is correlated with cheating, the causal effect of poverty on cheating in the field and the effectiveness of interventions for financially constrained people remain an open question.

Firm Volatility in Granular Networks

Author
Herskovic, Bernard, Bryan Kelly, Hanno Lustig, and Stijn Van Nieuwerburgh
Firm volatilities comove strongly over time, and their common factor is the dispersion of the economy-wide firm size distribution. In the cross-section, smaller firms and firms with a more concentrated customer base display higher volatility. Network effects are essential to explaining the joint evolution of the empirical firm size and firm volatility distributions. We propose and estimate a simple network model of firm volatility in which shocks to customers influence their suppliers. Larger suppliers have more customers, and customer-supplier links depend on customers' size.

Sequential Information Design

Author
Doval, Laura and Jeffrey Ely

We study games of incomplete information as both the information structure and the extensive-form vary. An analyst may know the payoff-relevant data but not the players' private information, nor the extenstive-form that governs their play. Alternatively, a designer may be able to build a mechanism from these ingredients. We characterize all outcomes that can arise in an equilibrium of some extensive-form with some information structure.

Choosing News Topics to Explain Stock Market Returns

Author
Glasserman, Paul, Kriste Krstovski , Harry Mamaysky , and Paul Laliberte

We analyze methods for selecting topics in news articles to explain stock returns. We find, through empirical and theoretical results, that supervised Latent Dirichlet Allocation (sLDA) implemented through Gibbs sampling in a stochastic EM algorithm will often overfit returns to the detriment of the topic model. We obtain better out-of-sample performance through a random search of plain LDA models. A branching procedure that reinforces effective topic assignments often performs best. We test these methods on an archive of over 90,000 news articles about S&P 500 firms.

Commitment vs. Flexibility with Costly Verification

Author
Halac, Marina and Pierre Yared

A principal faces an agent who is better informed but biased toward higher actions. She can verify the agent's information and specify his permissible actions. We show that if the verification cost is small enough, a threshold with an escape clause (TEC) is optimal: the agent either chooses an action below a threshold or requests verification and the efficient action above the threshold. For higher costs, however, the principal may require verification only for intermediate actions, dividing the delegation set.

Prior-Independent Optimal Auctions

Auctions are widely used in practice. While also extensively studied in the literature, most of the developments rely on the significant common prior assumption. We study the design of optimal prior-independent selling mechanisms: buyers do not have any information about their competitors and the seller does not know the distribution of values, but only a general class it belongs to.

Risky choice frames shift the structure and emotional valence of internal arguments: A query theory account of the unusual disease problem

Author
Wall, Daniel , Raymond D. Crookes, Eric Johnson , and Elke Weber

We examine a Query Theory account of risky choice framing effects — when risky choices are framed as a gain, people are generally risky averse but, when an equivalent choice is framed as a loss, people are risk seeking. Consistent with Query Theory, frames affected the structure of participants’ arguments: gain frame participants listed arguments favoring the certain option earlier and more often than loss frame participants. These argumentative shifts mediated framing effects; manipulating participants initial arguments attenuated them.

Accounting for Intangible Assets: Suggested Solutions

Author
Barker, Richard, Andrew Lennard, Stephen Penman , and Alan Teixeira

Current accounting practice expenses many investments in intangible assets to the income statement, confusing earnings from current revenues with investments to gain future revenues. This has led to increasing calls to book those investments to the balance sheet. Drawing on the relevant research, this paper proposes solutions for the accounting for intangible assets that contrast with balance sheet recognition, and compares them to current practice and the IFRS standards that dictate practice.

Can Global Uncertainty Promote International Trade?

Author
Baley, Isaac , Laura Veldkamp , and Michael Waugh

Common wisdom holds that uncertainty impedes trade—yet we show that uncertainty can fuel more trade in a simple general equilibrium trade model with information frictions. In equilibrium, increases in uncertainty increase both the mean and variance in returns to exporting. This implies that trade can increase or decrease with uncertainty, depending on preferences. Under general conditions on preferences, we characterize the importance of these forces using a sufficient statistics approach.

Destructive Creation at Work: How Financial Distress Spurs Entrepreneurship

Author
Babina, Tania

Using US Census employer-employee matched data, I show that employer financial distress accelerates the exit of employees to found start-ups. This effect is particularly evident when distressed firms are less able to enforce contracts restricting employee mobility into competing firms. Entrepreneurs exiting financially distressed employers earn higher wages prior to the exit and after founding start-ups, compared to entrepreneurs exiting non-distressed firms. Consistent with distressed firms losing higher-quality workers, their start-ups have higher average employment and payroll growth.

Vertical Integration, Supplier Behavior, and Quality Upgrading among Exporters

Hansman, Chris, Jonas Hjort , Gianmarco Leon-Ciliotta, and Matthieu Teachout
We study the relationship between firms' output quality and organizational structure. Using data on the production and transaction chain that makes up Peruvian fish meal manufacturing, we establish three results. First, firms integrate suppliers when the quality premium rises for exogenous reasons. Second, suppliers change their behavior to better maintain input quality when vertically integrated. Third, firms produce a higher share of high-quality output when weather and supplier availability shocks shift them into using integrated suppliers.

Cost Saving and the Freezing of Corporate Pension Plans

Author
Zeldes, Stephen, Joshua Rauh, and Irina Stefanescu

Companies that freeze defined benefit pension plans save the equivalent of 13.5% of the long-horizon payroll of current employees. Furthermore, firms with higher prospective accruals are more likely to freeze their plans. Cost savings would not be possible in a benchmark model in which i) all workers receive compensation equal to their marginal product and ii) workers value equally all identical-cost forms of pension benefits.

I Don't Know

Author
Backus, Matthew and Andrew Little
Political decision makers make choices in a complex and uncertain world, where even the most qualified experts may not know what policies will succeed. Worse, if these experts care about their reputation for competence, they may be averse to admitting what they don’t know. We model the strategic communication of uncertainty, allowing for the salient reality that sometimes the effects of proposed policies are impossible to know. Our model highlights the challenge of getting experts to admit uncertainty, even when it is possible to check predictive success.

Long Run Growth of Financial Data Technology

Author
Farboodi, Maryam and Laura Veldkamp

"Big data" financial technology raises concerns about market inefficiency. A common concern is that the technology might induce traders to extract others' information, rather than to produce information themselves. We allow agents to choose how much they learn about future asset values or about others' demands, and we explore how improvements in data processing shape these information choices, trading strategies and market outcomes. Our main insight is that unbiased technological change can explain a market-wide shift in data collection and trading strategies.

The Tail That Wags the Economy: Beliefs and Persistent Stagnation

Author
Kozlowski, Julian, Laura Veldkamp , and Venky Venkateswaran

The Great Recession was a deep downturn with long-lasting effects on credit, employment and output. While narratives about its causes abound, the persistence of GDP below pre-crisis trends remains puzzling. We propose a simple persistence mechanism that can be quantified and combined with existing models. Our key premise is that agents don't know the true distribution of shocks, but use data to estimate it non-parametrically. Then, transitory events, especially extreme ones, generate persistent changes in beliefs and macro outcomes.
