All these activities help to facilitate and streamline faculty research, and that of the doctoral students working with them.
An examination of research studies that assume the existence of the sleeper effect concept has revealed surprising results: this effect may be observed only under certain restrictive design conditions-with subsets of the population divided on the basis of personality characteristics.

In the study of consumer behavior, economics and marketing may perhaps seem headed on divergent paths. Economics models of man typically appear deterministic, while marketing models of man often are stochastic. This article links the microeconomic theory of demand (in a oligopoly situation) to a simple stochastic model of consumer behavior and, with data for one product, compares the empirical success of that model with those of various other models found in the literature.
The degeneration of orderly relationships between city governments and their employees seriously complicates the nature of government and democracy in urban America. While most cities have not yet experienced major minimal labor breakdowns, most city governments do suffer from seemingly chronic conditions, like inadequate revenues and spiraling costs, which easily can serve as catalysts for municipal labor crises. Data show that serious labor relations problems are no longer limited to a few unfortunate cities like New York, the subject of this study.
The purpose of this paper is to discover a theoretically sound model of asset valuation by reference to the basic underlying concept of Financial Position. It will be shown that several models of asset valuation can be developed from alternative assumptions or definitions of Financial Position, but that the application of certain metaphysical constraints brings about the rejection of some of these models.
This monograph reports on developing research that assesses the risk of equity investing from financial statements. The relevant information is conveyed by accounting numbers generated under accounting principles that respond to risk and its resolution, namely the realization principle and conservative accounting for investment. The recognition of this information leads to a financial statement analysis that extracts the risk information, to a reevaluation of performance metrics, and to revisions in risk factor models in asset pricing that utilize accounting information.
Bank balance sheet lending is commonly viewed as the predominant form of lending. We document and study two margins of adjustment that are usually absent from this view using microdata in the $10 trillion U.S. residential mortgage market. We first document the limits of the shadow bank substitution margin: shadow banks substitute for traditional “deposit-taking” banks in loans which are easily sold, but are limited from activities requiring on-balance-sheet financing.
Investment funds that claim to focus on socially responsible stocks have proliferated in recent times. In this paper, we verify whether ESG mutual funds actually invest in firms that have stakeholder-friendly track records. Using a comprehensive sample of self-labelled ESG mutual funds (as identified by Morningstar) in the United States from 2010 to 2018, we find that these funds hold portfolio firms with worse track records for compliance with labor and environmental laws, relative to portfolio firms held by non-ESG funds managed by the same financial institutions in the same years.
We show theoretically that a critical determinant of the attractiveness of VC-backed entrepreneurship for high-earning potential founders is the expected time to develop a startup’s initial product. This is because founder-CEOs’ cash compensation increases substantially after product development, alleviating the non-diversifiable risk that founders face at startup birth.
In this paper, I estimate the magnitude of an informational friction limiting credit reallocation to firms during the 2007 to 2009 financial crisis. Because lenders rely on private information when deciding which relationship to end, borrowers looking for a new lender are adversely selected. I show how to separately identify private information from information common to all lenders but unobservable to the econometrician by using bank shocks within a discrete choice model of relationships.
We decompose long-term nominal bond yields into real and inflation components in an international context using inflation-linked and nominal bonds. In contrast to extant results, real rate variation dominates the variation in inflation-linked and nominal yields. Cross-country nominal and inflation-linked yield correlations have declined since the Great Recession. Real rates are the main source of the correlation between nominal yields. Our results are robust to various alternative measurements of inflation expectations and the liquidity premium.
We use discounted cash flow analysis to measure the projected fiscal capacity of the U.S. federal government. We apply our valuation method to the CBO’s projections for the U.S. federal government’s primary deficits between 2022 and 2052 and projected debt outstanding in 2052. The discount rate for projected cash flows and future debt must include a GDP or market risk premium in recognition of the risk associated with future surpluses. Despite current low interest rates, we find that U.S. fiscal capacity is more limited than commonly thought.
We study the competitive provision and endogenous acquisition of political information. Our main result identifies a natural equilibrium channel through which a more competitive market decreases the efficiency of policy outcomes. A critical insight we put forward is that competition among information providers leads to informational specialization: firms provide relatively less information on issues that are of common interest and relatively more information on issues on which agents’ preferences are heterogeneous.
Information provision in games influences behavior by affecting agents' beliefs about the state, as well as their higher-order beliefs. We first characterize the extent to which a designer can manipulate agents' beliefs by disclosing information. We then describe the structure of optimal belief distributions, including a concave-envelope representation that subsumes the single-agent result of Kamenica and Gentzkow (2011). This result holds under various solution concepts and outcome selection rules.
We consider a portfolio selection problem for an investor who consumes at the end of a finite horizon. With important qualifications on the sufficiency part, we show that convergence of the optimal investment policy as the horizon becomes distant occurs if and only if the corresponding Arrow-Pratt coefficient of relative risk aversion converges as wealth increases. A major step in the proof shows that convergence of the Arrow-Pratt coefficient of relative risk aversion is equivalent to regular variation of the marginal utility function.
Economic frictions pervade the founding, financing, growing, and exiting of high-growth entrepreneurial firms. This chapter considers one friction that currently affects a small, but important, set of entrepreneurs: racial and gender discrimination. I first collect facts from a large empirical literature that show clear gender and race gaps in participation and financing of startups. Female founders manage 16-25% of all startups, while Black entrepreneurs rarely exceed 3% of the startup population.
We study the role of commitment in communication and its interactions with rules, which determine whether information is verifiable. Our framework nests models of cheap talk, information disclosure, and Bayesian persuasion. It predicts that commitment has opposite effects on information transmission under the two alternative rules. We leverage these contrasting forces to experimentally establish that subjects react to commitment in line with the main qualitative implications of the theory. Quantitatively, not all subjects behave as predicted.
We provide evidence that in certain contexts, firms set upward-striving goals and that this upward striving yields significant performance and visibility benefits. We develop a model of variable attention in which, as firms’ performance levels approach cognitively salient round numbers, managers strategically shift their focus from easier-to-reach goals based on historical and social reference points to more challenging goals that provide external visibility and capital market benefits.
Acquisitions can shift the market structure of a digital platform in a way that affects subsequent market entries and hence the platform’s base of complementors. Synergies that complementor acquirers accrue can be entry-deterring. We develop a two-by-two typology of acquisition synergies in a multisided platform based on sides (user side or complementary-technology side) and economies (scale or scope).
The equity variance risk premium is the expected compensation earned for selling variance risk in equity markets. The variance risk premium is positive and shows only moderate persistence. High variance risk premiums coincide with the left tail of the consumption growth distribution shifting down. These facts, together with risk neutral skewness being substantially more negative than physical return skewness, refute the bulk of the extant consumption-based asset pricing models. We introduce a tractable habit model that does fit the data.
