Differences between Politically Connected and Nonconnected Firms: A Cross-Country Analysis

Evidence from firms in 47 countries shows that companies with political connections have higher leverage and higher market shares, but they underperform compared to nonconnected companies on an accounting basis. Differences between connected and unconnected firms are more pronounced when political links are stronger. Differences also vary depending on the level of corruption and the degree of economic development in individual countries.     

The quality of accounting information in politically connected firms

We document that the quality of earnings reported by politically connected firms is significantly poorer than that of similar non-connected companies. Our results are not due to firms with ex-ante poor earnings quality establishing connections more often. Instead, our results suggest that, because of a lesser need to respond to market pressures to increase the quality of information, connected companies can afford disclosing lower quality accounting information. In particular, lower quality reported earnings is associated with a higher cost of debt only for the non-politically connected firms in the sample.     

Business groups and the incorporation of firm-specific shocks into stock prices

Firm-specific information has a damped effect on business group-affiliated firms’ stock prices. Such firms’ idiosyncratic stock returns are less responsive to idiosyncratic commodity price shocks than are the idiosyncratic returns of otherwise similar unaffiliated firms in the same country and commodity-sensitive industry. Using global commodity shocks means we assess responses to common idiosyncratic shocks of the same magnitude, frequency, and observability. Further identification follows from difference-in-difference tests exploiting successful and matched exogenously failed control block transactions. We conclude that business group firms’ stock prices provide less firm-specific information to capital providers and managers.     

Death by Pokémon GO: The Economic and Human Cost of Using Apps While Driving

We investigate the link between smartphone usage by drivers and increases in insurance premiums by using police accident reports and exploiting the introduction of the augmented reality game Pokémon GO as a natural experiment. We document a disproportionate increase in crashes, vehicular damage, injuries, and fatalities in the vicinity of locations where users can play the game while driving. Ignoring incremental lives lost, the lower bound estimate of the cost of users playing the game while driving translates to an increase in insurance premiums of 2.47 percent.     

Design of the optimal feeding policy in an assembly system

This paper describes an innovative and integrated approach to component management optimization within a production/assembly system. In a mixed-models assembly process the handling of parts and components for each work station represents a substantial variable that can greatly affect job duration and efficiency. This paper is strictly related to Assembly to Order/Manufacturing to Order (ATO and MTO) systems, where lead time has to be very short and flexibility is at its maximum level. In Assembly to Order (ATO) or Make to Order (MTO) systems, the production is increasingly getting more customized in response to the demand, thanks to the progresses reached in both manufacturing and information technologies. It is becoming increasingly possible to assemble or make products specifically in response to the requests of either end customers or retailers. As a consequence of such customization, the design of the whole system must take into direct account several elements: parts warehouses location, feeding policies and feeding systems. In some cases the collection of parts and components required picking activities, in other the movement of entire units load.In several instances experts have analyzed the problems about material centralization/decentralization, storage policies and assembly feeding problem in different and independent ways, while the problem needs an integrated approach. While many researches regarding components allocation problems in ATO and MTO systems, did not consider feeding policies, material picking, packing activities and vehicles optimization, this paper cover focuses on filling such gap using an integrated framework that considers both aspects of the problem: the centralization/decentralization of components in order to minimize the total storage costs and the right feeding policies.Feeding problems in assembly lines are some of the most important aspects to consider during the analysis and design of an assembly system, to allow the maximization of efficiency and flexibility. To reach such goals, a multi-factorial analysis has been carried out during this experiment and will validate the introduced framework. An industrial application of the introduced framework is illustrated to explain its real significant production implication.     

Discussion of “Corporate Political Connections and Tax Aggressiveness”

Kim and Zhang (2015) study the relation between corporate political connections and tax aggressiveness. In this discussion, I identify and evaluate three main limitations of their paper: the measurement of political connections, the empirical design, and the possible reasons behind the documented results. I build on these small shortcomings to provide suggestions for further contributions in this area of research.
