Do insiders time management buyouts and freezeouts to buy undervalued targets?

We provide evidence that managers and controlling shareholders time management buyouts (MBOs) and freezeout transactions to take advantage of industry-wide undervaluation. Portfolios of industry peers of MBO and freezeout targets show significant alphas of around 1% per month over the 12-month period following the transaction. These returns are not explained by a battery of risk factors or empirical methodologies, but exhibit significant heterogeneity across deals. Additional tests show that, on average, abnormal returns to industry peers are a reliable proxy for those to the target firm. Further, MBOs and freezeouts are announced during troughs of industry profitability.     

企业创新投入对行业成长性的影响

在“万众创新”背景下，已有文献关注到企业创新投入在微观层面的经济后果，但对中观视角行业表现的作用机制研究较少。以我国沪、深两市A股上市公司为研究对象，探究企业创新投入对行业成长性的影响机理以及行业研发环境和企业市场势力的调节效应。结果发现，企业研发资金投入强度和技术人员投入强度与行业成长性间存在显著正相关关系，行业技术环境和行业政策环境起正向调节效应，但企业市场势力会削弱上述正向关系。研究结论不受内生性问题的影响，且稳健性检验结果并未发生改变。建议构建包含政府、行业和企业的协同创新体系，通过创新政策支持、优势资源整合及良好环境的营造，促进企业创新投入和行业可持续发展。     

Inconsistent Signals,Earnings Announcements,and Market Uncertainty

We test the proposition in Johnstone (2016) that new information may lead to higher, rather than lower, uncertainty about firms’ future payoffs. Based on the Bayesian rule, we hypothesize earnings news that is inconsistent with investors’ prior belief will lead to higher market uncertainty. Using earnings signals in the past few quarters to proxy for investors’ prior belief, we find supporting evidence that, relative to consistent earnings news, inconsistent news results in an increase in market uncertainty measured by implied volatility. Inconsistent earnings news has a larger effect on market uncertainty when prior beliefs are stronger and when the news is negative. Overall, our evidence highlights the importance of prior belief and inconsistent signals in understanding the effect of earnings news on market uncertainty.     

Market or limit orders?

In this paper we investigate the problem of optimal order placement of an asset listed on an exchange using both market and limit orders in a simple model of market dynamics. We seek to understand under which settings it is optimal to place limit or market orders. Limit orders typically lower transaction costs but increase the risk of incomplete order execution, whereas market orders typically have higher transaction costs but are guaranteed to be executed. Rather than considering order book dynamics to determine if a limit order is executed we rely on price dynamics for this. We look at implementation shortfall in this setup with market impact of trading and propose a dynamic program to find the optimal placement of both market and limit orders for risk-neutral and risk-averse traders. With this we find a bound on the expected cost of trading and show that a trader who behaves optimally should always expect to pay less to trade less. We then solve the dynamic program numerically and examine optimal order placement strategies. We find that the decision between market and limit orders is sensitive to price volatility, risk aversion, and trading costs.     

Corporate governance and family firm performance during the Global Financial Crisis

We investigate the impact of corporate governance on accounting and market performance relationships of family firms during the Global Financial Crisis (GFC). We expect the monitoring aspects of corporate governance to complement the long-term orientation of family firms, improving the value relevance of accounting and market performance during times of exogenous financial shocks such as the GFC. We find that the family-firm value is more sensitive to book value than earnings changes. We also find better corporate governance, irrespective of whether it is a family firm or non-family firm, is associated with better accounting and market performance during the GFC.     

Effect of concentration in airline market on Spanish airport technical efficiency

This paper tries to measure the effect of airline market concentration on airport technical efficiency. With this aim, a Stochastic Frontier Analysis (SFA) is applied, estimating with a one-step procedure technical efficiency and the effect of airlines' market power on that efficiency. Results suggest that when airports are lowly concentrated increasing concentration reduces such inefficiencies. However, this effect practically disappears when airports are highly concentrated. Additionally, the government's policies to improve airports' performance seems to have a positive effect in the short run.     

Limit order books,uninformed traders and commodity derivatives: Insights from the European carbon futures

This paper provides a suitable model for studying the strategic behavior of uninformed investors that trade commodity derivatives via limit order books. Two main testable implications are obtained after solving for the model equilibrium. The adverse selection costs of uninformed traders depend on the inflow of market orders and their risk aversion. Next, the adverse selection costs of uninformed buyers and sellers and the difference of their asset valuations determine the size of their bid-ask spread.An analysis of European carbon futures data confirms the relevance of these implications. Moreover, we detect a diagonal effect that results in a positive correlation of market orders, which is driven by adverse selection, then by order splitting strategies and by imitative strategies of uninformed traders to a lesser extent.     

Risk allocation under liquidity constraints

Risk allocation games are cooperative games that are used to attribute the risk of a financial entity to its divisions. In this paper, we extend the literature on risk allocation games by incorporating liquidity considerations. A liquidity policy specifies state-dependent liquidity requirements that a portfolio should obey. To comply with the liquidity policy, a financial entity may have to liquidate part of its assets, which is costly.The definition of a risk allocation game under liquidity constraints is not straightforward, since the presence of a liquidity policy leads to externalities. We argue that the standard worst case approach should not be used here and present an alternative definition. We show that the resulting class of transferable utility games coincides with the class of totally balanced games. It follows from our results that also when taking liquidity considerations into account there is always a stable way to allocate risk.     

To Ban or not to ban rate parity,that is the question… or not?

Considering the heated debate in the hotel industry about the rate parity clause and the appropriateness of its ban to give rise to rate disparity, this article analyzes the hotel performance that has resulted from the rate parity prohibition established in some European countries, by looking into the market value of the hotels involved. The empirical analysis conducted on a sample of hotel companies trading on the stock exchange in Germany and France shows that the approval of the rate parity ban generates positive abnormal returns. However, an increase in risk is detected. It seems that, while the prospects of greater autonomy to set prices in the hotel industry and stronger competition in the online distribution industry are looked at positively, the hotels will have to deal with a customer’s potential higher perception of price unfairness, less control over its own brand and a greater likelihood of price wars.
