Retail investors’ trading and stock market liquidity

The paper investigates the relation between retail investors’ participation in trading and aggregate stock market liquidity. The findings show a positive and significant relation between retail investors’ trading and stock market liquidity. Examination of the determinants of retail investors’ trading reveals that, on average, retail investors with more diversified trading activity tend to trade when liquidity is higher, the frequency of their arrival to the market is not affected by the level of liquidity, and retail investors are willing to trade at a lower liquidity level as sellers than as buyers. Moreover, retail investors’ trading does not create price noise at the aggregate market level. Overall, the evidence suggests that retail investors contribute to market quality.     

Rationalizing investors’ choices

Assuming that agents’ preferences satisfy first-order stochastic dominance, we show how the Expected Utility paradigm can rationalize all optimal investment choices: the optimal investment strategy in any behavioral law-invariant (state-independent) setting corresponds to the optimum for an expected utility maximizer with an explicitly derived concave non-decreasing utility function. This result enables us to infer the utility and risk aversion of agents from their investment choice in a non-parametric way. We relate the property of decreasing absolute risk aversion (DARA) to distributional properties of the terminal wealth and of the financial market. Specifically, we show that DARA is equivalent to a demand for a terminal wealth that has more spread than the opposite of the log pricing kernel at the investment horizon.     

Interactions between investors’ fear and greed sentiment and Bitcoin prices

This paper examines the relationship between investor fear in the cryptocurrency market and Bitcoin prices by considering the potential effects of the ongoing COVID-19 pandemic during the period of May 5, 2018 and December 10, 2020. The existence of structural changes in the time series for the full sample reveals a non-constant causality between fear sentiment and Bitcoin prices, which leads us to apply a bootstrap rolling window Granger causality test. Our results show that both negative and positive interactions between fear sentiment and Bitcoin prices occur during several subperiods. The nature of these interactions changes significantly before and during the pandemic. Thus, we contribute to the fast-growing literature on the financial effects of the COVID-19 global pandemic, as well as to the debate on whether to classify Bitcoin as a new asset, speculative investment, currency, or safe haven asset.     

Institutional investors’ ownership stability and their investee firms’ equity mispricing

This study examines the impact of institutional investors' equity ownership stability and their investment horizon to determine the impact on their investee firms' equity mispricing. Mispricing represents the difference between a firm’s market and fundamental values. We treat institutional investors as a heterogenous group, i.e., dedicated, transient, or quasi-indexer as defined by Bushee, 1998, Bushee, 2001 since their categorization determines their trading strategy. Higher institutional ownership, higher stability in institutional investors' equity ownership, and institutional investors classified as long-term are all associated with lower equity mispricing at investee firms.     

Bank Relationships and Private Firms’ Financial Reporting Quality

Private firms with relatively high (proprietary) costs of disclosure may benefit from a close relationship with a bank. Relationship lending is based on intertemporal contracting that assumes that the bank is able to acquire private information about the firm and, moreover, to keep this information private. For both reasons, we expect and find that private firms with fewer bank relationships exhibit lower levels of financial reporting quality. Controlling for many other factors, firms with a single bank relationship disclose their financial reports about 14 days later. The size of such firms’ financial reports is also smaller, containing approximately 8% fewer words than the median report. Firms with a single bank relationship also exhibit more earnings management, exceeding the median value of the three-year sum of absolute discretionary accruals by about 20%. The results are robust to different econometric specifications, including endogeneity concerns. They indicate that private firms choose to be opaque in the presence of fewer lending relationships.     

Tail risk and investors’ concerns: Evidence from Brazil

I estimate tail risk for Brazil from January 2001 to July 2020 and investigate the origins of tail risk variation. The tail risk measure peaks at stock market crashes, financial crises, political shocks and disaster events such as the coronavirus pandemic. Moreover, I find that tail risk is countercyclical, has strong predictive power for market returns and negatively predicts real economic activity. In order to identify the investors’ concerns associated with tail risk, I extract daily news from the largest financial newspaper in Brazil. The co-movement between news and tail risk indicates that tail risk variation is mainly driven by disaster concerns, followed by economic and government uncertainty. While economic uncertainty explains the countercyclical property of tail risk, investors only require compensation for bearing tail risk implied by disaster concerns. Similarly, tail risk negatively impacts real outcomes because of the disaster concerns that it identifies. These findings support recent models explaining asset pricing puzzles with time-varying disaster risk.

International Financial Reporting Standards and Private Firms’ Access to Bank Loans

Prior research has focused on publicly listed firms when examining the economic consequences of adopting International Financial Reporting Standards (IFRS). This study extends the literature by examining the ability of private firms to attract bank loans through the use of IFRS. Based on firm-level data from 25 countries, we show that private firms that voluntarily use IFRS are associated with a higher propensity to attract debt from foreign banks. We find no such association when examining their relationships with domestic banks. Supplementary analyses show that the results are mainly driven by private firms operating in countries with strong regulatory enforcement. The findings suggest that, conditional on adequate enforcement, the use of IFRS provides useful information for foreign non-relationship banks.     

Economic policy uncertainty and industry risk on China’s stock market

We propose a dynamic mixture Copula with time-varying weight, which is endowed with generalized autoregressive score dynamics. Based on this model, we portray the lower-tail dependence between the return of WIND first-level industry and CSI-300 index as a proxy variable for the industry risk in China’s stock market, and use the VAR-GARCH-in-mean model based on BEKK-GARCH to deconstruct the different impact of the economic policy uncertainty (EPU) on industry risk of the first and second moments in terms of four policy categories, namely fiscal policy, monetary policy, trade policy, and foreign exchange rate and capital account policy. The results are followed. Firstly, the risk of Consumer Discretionary is averagely the highest, while the risk of Utilities remains the lowest. Secondly, category-specific EPU has no significant mean spillover to the risk of overall industries, while the variance spillover is significant for all the cases. Thirdly, except for Real Estate, the GARCH-in-mean effect is not significant of EPU on industry risks. Further more, all those three kinds of impact show industrial heterogeneities. To avoid systemic risks, we advise that the issue of economic policy should be forward-looking, consistent, and targeted, especially for sensitive industries.     

Corporate R&D and firm efficiency: evidence from Europe’s top R&D investors

The main objective of this study is to investigate the impact of corporate research and development (R&D) activities on firm performance, measured by labour productivity. To this end, the stochastic frontier technique is used on a unique unbalanced longitudinal dataset comprising top European R&D investors over the period 2000–2005. In this framework, this study quantifies technical inefficiency of individual firms. From a policy perspective, the results of this study suggest that if the aim is to leverage firms’ productivity, the emphasis should be put on supporting corporate R&D in high-tech sectors and, to some extent, in medium-tech sectors. On the other hand, corporate R&D in the low-tech sector is found to have a minor effect in explaining productivity. Instead, encouraging investment in fixed assets appears important for the productivity of low-tech industries. Hence, the allocation of support for corporate R&D seems to be as important as its overall increase and an ‘erga omnes’ approach across all sectors appears inappropriate. However, with regard to technical efficiency, R&D intensity is found to be a pivotal factor in explaining firm efficiency and this turns out to be true for all industries.     

Daily momentum profits with firm characteristics and investors’ optimism in the Taiwan market

In this paper, we examine two different investing attitudes, being conservative sentiment which mitigates the momentum effect and, alternatively, the optimistic sentiment which strengthens such an effect. Where the stock market index levels close near a previous peak level, the impact of the index on momentum profits can assist in identifying such sentiments. In this study, we investigate the price and price-size momentum strategies in Taiwan of short formation periods of less than a month. The results indicate that investors adopt optimistic attitudes towards the 5-day and 20-day highs in the market index, whereas a conservative attitude is adopted at the 52-week high. Using the quantile regression model, the results indicate that the momentum effect is mitigated when the stock index price is relatively high for higher momentum profits. On the other hand, the momentum effect is strengthened when the stock index price is relatively high for lower momentum profits. However, the high point of the stock index is not found to have any impact on the price-B/M momentum effect.     

Mutual fund flows and investors’ expectations in BRICS economies: Implications for international diversification

This paper empirically examines the relationship between different classes of mutual funds, measures of investors’ expectations and business cycle movements in the BRICS markets over the 1996Q1-2017Q3 period. Applying the Panel Vector Autoregressive (PVAR) model in a Generalized Method of Moments (GMM) setting, the results suggest a strong causal relationship between mutual fund flows and measures of investors’ future expectations. In particular, fund flows are forward-looking and assist in forecasting real economic conditions. Moreover, investors choose to invest in riskier funds when economic conditions are good, while they prefer safer options in poor economic situations. These findings have important implications for international diversification.

Assessing the uncertainty in central banks’ inflation outlooks

Recent research has found that macroeconomic survey forecasts of uncertainty exhibit several deficiencies, such as horizon-dependent biases and lower levels of accuracy than simple unconditional uncertainty forecasts. We examine the inflation uncertainty forecasts from the Bank of England, the Banco Central do Brasil, the Magyar Nemzeti Bank and the Sveriges Riksbank to assess whether central banks’ uncertainty forecasts might be subject to similar problems. We find that, while most central banks’ uncertainty forecasts also tend to be underconfident at short horizons and overconfident at longer horizons, they are mostly not significantly biased. Moreover, they tend to be at least as precise as unconditional uncertainty forecasts from two different approaches.     

Understanding knowledge workers’ job performance: a perspective of online and offline communication networks

Optimal communication networks allow the knowledge workers to get high job performance. As knowledge workers are increasingly relying on the online interaction, it is important to understand how online and offline communication networks respectively enhance job performance. An empirical study is performed using data collected from 103 knowledge workers in a high-tech company. The results show that job performance of knowledge workers is positively influenced by online communication network properties and negatively influenced by offline communication network properties. The positions of knowledge workers within the offline whole communication network negatively moderate the above effects, such that the relationships between job performance and communication network properties are weaker when a knowledge worker occupies a central position. Theoretical contributions and practical implications are discussed.     

National sovereignty and consumer sovereignty: Some consequences of Brazil’s economic opening

Brazil’s move toward greater openness in its foreign trade and capital account since the 1980s, reflects a weakening of the exercise of national sovereignty for economic objectives. In this paper, we argue that consumer sovereignty has been correspondingly increased. There are costs and benefits to Brazil from both kinds of sovereignty. Increasing constraints on macroeconomic policy making have been accompanied by an increase in the choices open to many individuals. The latter increase, however, has been limited by a highly skewed distribution of income, which has persisted despite the profound changes in economic policy.     

Which institutional investors matter for firm survival and performance?

Using data that spans three decades, we assess the diverse roles of institutional investors in impacting survival and performance of chronically underperforming firms and contrast the results for consistently overperforming firms. We find material differences in investor roles and investment returns between these samples. Differentiating among institutional types, controlling for prior performance and attrition bias provides insights unattainable by examining aggregated holdings. For underperformers, results are negative for activist pension funds and long-term institutions, positive for activist hedge funds and short-term institutions, and mixed for institutional blockholders.     

Accruals quality,information risk,and institutional investors’ trading behavior: Evidence from the Korean stock market

This study analyzes the effect of firm-specific information risk, measured by accruals quality, on the cost of capital using institutional investors’ trading behavior. Institutional investors in firms with lower accruals quality increase their net selling in later years. Furthermore, these investors’ net selling is relevant to the innate and discretionary factors of accruals quality. This relationship is stronger for foreign institutions than for domestic institutions, and it is mostly observed under favorable macroeconomic conditions. We do not observe this relationship for large business groups connected by shares.     

The risk spillover between China’s economic policy uncertainty and commodity markets: Evidence from frequency spillover and quantile connectedness approaches

Based on the frequency spillover method extended by Baruník and Křehlík (2018), we explore the risk spillover relationship between China’s economic policy uncertainty (CNEPU) and commodity futures in different frequency domains with daily settlement price data of 14 commodity futures in China. The results show that the risk spillover relationship between CNEPU and the commodity market mainly occurs in the short term. Quantile connectedness results show that economic policy uncertainty, which mainly plays the role of risk transmitter, is more closely related to the commodity market during the market boom and recession. Soybeans, soybean meal, and corn have shown high investment value in the process of market recovery, which is exposed to less risk spillover from policy uncertainty. Finally, the economic crisis with different characteristics will have specific impacts on asymmetric risk spillovers based on certain impact mechanisms.
