Liability of Foreignness of Emerging Market Firms: The Country of Origin Effect on Russian IT Companies

Foreign subsidiaries are considered to be at a disadvantage compared to domestic firms in foreign markets. The liability of foreignness (LOF) concept was first attempted in order to address the issue of these disadvantages. Although internationalization of emerging market firms (EMFs) is a very hot topic, there is very little research of LOF of EMFs. In this article, we investigate the sources of LOF and determine the extent of the country-of-origin (COO) effect on Russian IT firms. We also discuss how Russian firms may overcome the LOF, and we propose the mitigation strategies that will help them to decrease negative COO effect.     

Impact of bitcoin futures on the informational efficiency of bitcoin spot market

This study examines the informational efficiency of the bitcoin spot market by evaluating the predictive power of mechanical trading rules designed to exploit price continuation. Significant return predictability is found until the introduction of bitcoin futures in December 2017. The forecasting ability of trend‐chasing trading rules declines dramatically afterwards. Although evidence suggests that the introduction of bitcoin futures has increased the informational efficiency of the bitcoin spot market, no signs of improvement in informational efficiency are found in ethereum, the second‐largest cryptocurrency—following the introduction of bitcoin futures.     

Global industry portfolios and short-term predictability of returns: Is it there?

This paper explores the degree of success of a large set of active trading rules that have been popularized in the literature on the short-term predictability of returns in equity and foreign exchange markets by extending the scope of research in three dimensions: global portfolios, industry portfolios, and exclusive versus inclusive portfolios. Our results show that after adjusting for (1) the impact of nonsynchronous prices in the reported closing index levels which causes spurious autocorrelations in returns, (2) data snooping bias caused by searching through a large number of possible trading strategies in order to find a few that yield superior in-sample performance, and (3) transaction costs that reduce any profits from active trading, the risk-adjusted profits generated by short-term trend chasing trading rules are generally not statistically significant and the hypothesis of no outperformance of trading rules over either buy-and-hold or risk-free benchmark return cannot be rejected in most industries. Such findings favor short-term market efficiency and are hardly comforting for active traders.     

The surplus prior to ruin and the deficit at ruin for a correlated risk process

This paper presents an explicit characterization for the joint probability density function of the surplus immediately prior to ruin and the deficit at ruin for a general risk process, which includes the Sparre-Andersen risk model with phase-type inter-claim times and claim sizes. The model can also accommodate a Markovian arrival process which enables claim sizes to be correlated with the inter-claim times. The marginal density function of the surplus immediately prior to ruin is specifically considered. Several numerical examples are presented to illustrate the application of this result.     

The value relevance of earnings in a transition economy: The case of Romania

We investigate the value relevance of earnings on the Bucharest Stock Exchange. We find that the association between accounting earnings and stock returns is comparable to the levels reported by studies conducted on more mature markets, and that it is higher for securities issued by small companies. Excluding losses from the analysis increases the value relevance of earnings, which confirms the transitory nature of negative earnings, already documented by prior studies. We also find that the regression coefficient of earnings changes is negative and we provide evidence consistent with the hypothesis that it is a consequence of the relative inefficiency of the market. Finally, the “prices lead earnings” hypothesis formulated for more mature markets is not supported by our results.     

Trading networks and liquidity provision

We study the profitability of traders in two fully electronic and highly liquid markets: the Dow and Standard & Poor?s 500 e-mini futures markets. Using unique information that identify counterparties to a transaction, we show and seek to explain the fact that the network pattern of trades captures the relations between behavior in the market and returns. Our approach includes a simple representation of how much a shock is amplified by the network and how widely it is transmitted. This representation provides a possible shorthand for understanding the consequences of a fat-finger trade, a withdrawing of liquidity, or other market shock.     

Genetically Modified Crops and Product Differentiation: Trade and Welfare Effects in the Soybean Complex

A partial equilibrium four-region world trade model for the soybean complex is developed in which Roundup Ready (RR) products are weakly inferior substitutes to conventional ones, RR seeds are priced at a premium, and costly segregation is necessary to separate conventional and biotech products. Solution of the calibrated model illustrates how incomplete adoption of RR technology arises in equilibrium. The United States, Argentina, Brazil, and the Rest of the World (ROW) all gain from the introduction of RR soybeans, although some groups may lose. The impacts of RR production or import bans by the ROW or Brazil are analyzed. U.S. price support helps U.S. farmers, despite hurting the United States and has the potential to improve world efficiency.     

The transition to an oil contraction economy

A normative analysis of the problem of optimal extraction of a nonrenewable resource is considered. The economy depends on the essential nonrenewable resource and the rate of the resource extraction is increasing over time. At some point the government gradually switches to a sustainable (in sense of non-decreasing consumption over time) pattern of the resource extraction. Different approaches are offered for the construction of the paths of switching to decreasing resource use. Some seemingly attractive short-run policies of switching to decreasing extraction can run counter to long-run criteria. If we consider the maximin principle, applied to the negative shock on the output percent change, as the short-run criterion, then the optimal transition path can be consistent with the long-run government goals. It is shown analytically and numerically that there are values of parameters for the transition paths of extraction that consumption along these paths is asymptotically constant or infinitely growing. A new approach to the Rawlsian maximin criterion which allows for growth of consumption is offered.     

Chasing noise

We present a simple model in which rational but uninformed traders occasionally chase noise as if it were information, thereby amplifying sentiment shocks and moving prices away from fundamental values. In the model, noise traders can have an impact on market equilibrium disproportionate to their size in the market. The model offers a partial explanation for the surprisingly low market price of financial risk in the spring of 2007.
