Is Real Earnings Smoothing Harmful? Evidence from Firm‐Specific Stock Price Crash Risk

This study examines whether and when real earnings smoothing influences firm‐specific stock price crash risk. Using a sample of U.S. public firms for the years 1993 through 2014, we find real earnings smoothing to be positively associated with firm‐specific stock price crash risk. This finding is consistent with the view that real earnings smoothing helps managers withhold bad news, keep poor‐performing projects, conceal resource diversion, and engage in ineffective risk management, which increases crash risk. Further, we find a stronger relation between crash risk and real earnings smoothing when firm uncertainty is higher, product market competition is lower, and balance sheet constraint is higher. Overall, our study suggests that real earnings smoothing destroys shareholder value in that it increases stock price crash risk.     

Social security and economic performance in Portugal: after all that has been said and done how much has actually changed?

This paper provides an empirical estimate of the macroeconomic effects of the Portuguese pay-as-you-go social security system based on data for the period 1970?C2007 and on VAR estimates using GDP, the unit cost of labor, the unemployment rate, the savings rate and social security spending. The major findings are twofold. First, growing social security spending has had detrimental effects on all of the private sector variables under consideration suggesting the existence of sizable inefficiencies. Second, these inefficiencies persist despite the successive reforms that took place over the last two decades. These results highlight the need for structural reforms of the pay-as-you-go system thereby addressing the sources of these inefficiencies, regardless of whether or not the system is financially sustainable. Furthermore, any reforms designed to address sustainability concerns cannot ignore these inefficiencies or risk making them even worse and thereby hindering the quest for sustainability itself.     

Behavioral Finance in Brazil: A Bibliometric Study from 2007 to 2017

This article analyzed 58 Brazilian journals in order to address the gap unexplored in the past 10?years by congresses and periodical journals. In this research, an analysis based on keywords was used, followed by analysis of citations and co-citations that allowed to verify: an average growth of 20% p.a. of publications; the most common focus was replication of Kahneman and Tversky; the most studied group tended to be university students; quality has failed to accompany the increase in publications; public institutions publish more. A gap was perceived in the surveying of financial managers and investors, as well as bias and heuristics as a subject.     

Expected Default Probabilities in Structural Models: Empirical Evidence

We apply a set of structural models (Black and Cox 1976; Collin-Dufresne and Goldstein 2001; Ericsson and Reneby 1998; Leland and Toft 1996; Longstaff and Schwartz 1995; Merton 1974) to estimate expected default probabilities (EDPs) for a sample of failed and non-failed UK real estate companies. Results are generally consistent with models’ predictions and estimates of EDPs for different models are closely clustered. The results of z-scores and synthetic ratings misclassify 33% of the total sample in contrast to 8% misclassification by structural models. Further analysis of EDPs based on logistic regressions suggests the observed misclassification of the companies by structural models is due to special company management and/or regulatory circumstances rather than limitations of these models.      

Import Tariff and Exchange Rate Transmission in a Small Open Economy

ABSTRACT

We present a small open economy DSGE model with internal and external sticky prices in an incomplete exchange rate pass-through environment. Import tariff is included as another variable that affects the law of one price. The model is calibrated for the Brazilian economy, and the responses of endogenous variables to shocks in import tariff, aggregate supply, monetary policy, and foreign interest are analyzed. The long-run effect of the first shock is deterioration in the terms of trade because the exchange rate appreciation following this shock offsets the initial effect of the increase in import tariff.     

Empirical comparisons of some tests of separate families of hypotheses

Summary This paper is devoted to a comparison of the asymptotic tests of separate families of hypotheses proposed byCox [1961, 1962] and byAtkinson [1970]. The adequacy of the asymptotic results for finite samples is investigated and some conclusions reached. An examination of the terms which differentiate the two procedures is made. Empirical simulated results are discussed for cases involving the exponential, the lognormal and the Weibull distributions.

Zusammenfassung In dieser Arbeit wird ein Vergleich angestellt zwischen den Vorschlägen vonCox [1961, 1962] undAtkinson [1970] über asymptotische Tests separierter Familien von Hypothesen. Die Angemessenheit der asymptotischen Resultate für endliche Proben wird untersucht und einige Folgerungen gezogen. Eine Prüfung der Terme, die die beiden Verfahren differenzieren, wird vorgenommen. Empirisch simultierte Resultate werden distribuiert für Fälle mit exponential, lognormal und Weibull Verteilungen.

     

Public Investment in Transportation Infrastructure and Economic Performance in Portugal

In this paper, we use a VAR approach to investigate the effects of public investment in transportation infrastructures on private investment, employment, and output in Portugal. Estimation results suggest that public investment crowds in private investment and employment, and has a strong positive effect on output. We estimate that one euro in public investment increases output in the long‐term by 9.5 euros, which corresponds to a rate of return of 15.9%. These figures imply that there are strong long‐term budgetary benefits from public investment in the form of increased future tax revenues. A closer look at the effects of different types of public investment uncovers the same general patterns. These results are very important from a public policy perspective. They suggest that the strategy followed by the Portuguese authorities of investing in public infrastructures is justified, both from a long‐term development perspective and a long‐term public budgetary perspective.     

Liquidity and conditional portfolio choice: A nonparametric investigation

This paper studies the relation between liquidity and optimal portfolio allocations. Given that the portfolio problem of a constant relative risk aversion investor does not have a closed-form solution, we use a nonparametric approach to estimate the optimal allocations. Using a sample of NYSE stocks from 1963–2000, we find that the optimal portfolio weight in small stocks is strongly increasing in liquidity at short daily and weekly horizons. This result is consistent for three different measures of liquidity: price impact, dollar volume, and turnover. However, liquidity does not influence the optimal portfolio choice for large stocks, nor for longer monthly investment horizons.
