In search of global leaders

For all the talk about global organizations and executives, there's no definitive answer to the question of what we really mean by "global." A presence in multiple countries? Cultural adaptability? A multilingual top team? We asked four CEOs and the head of an international recruiting agency--HSBC's Stephen Green, Schering-Plough's Fred Hassan, GE's Jeffrey-lmmelt, Flextronics's Michael Marks, and Egon Zehnder's Daniel Meiland--to tell us what they think. They share some common ground. They all agree, for example, that the shift from a local to a global marketplace is irreversible and gaining momentum. "We're losing sight of the reality of globalization. But we should pay attention, because national barriers are quickly coming down", Daniel Meiland says. "If you look ahead five or ten years, the people with the top jobs in large corporations ... will be those who have lived in several cultures and who can converse in at least two languages." But the CEOs also disagree on many issues--on the importance of overseas assignments, for instance, and on the degree to which you need to adhere to local cultural norms. Some believe strongly that the global leader should, as a prerequisite to the job, live and work in other countries. As Stephen Green put it, "If you look at the executives currently running [HSBC's] largest businesses, all of them have worked in more than one, and nearly all in more than two, major country markets." Others downplay the importance of overseas assignments. "Putting people in foreign settings doesn't automatically imbue new attitudes, and it is attitudes rather than experiences that make a culture global," says Fred Hassan. The executives' essays capture views that are as diverse and multidimensional as the companies they lead.     

Homeownership as a Constraint on Asset Allocation

Personal preferences and financial incentives make homeownership desirable for most families. Once a family purchases a home they find it impractical (costly) to frequently change their ownership of residential real estate. Thus, by deciding how much home to buy, a family constrains their ability to adjust their asset allocation between residential real estate and other assets. To analyze the impact of this constraint on consumption, welfare, and post-retirement wealth, we first investigate an individual’s optimal asset allocation decisions when they are subject to a “homeownership constraint.” Next, we perform a “thought experiment” where we assume the existence of a market where a homeowner can sell, without cost, a fractional interest in their home. Now the housing choice decision does not constrain the individual’s asset allocations. By comparing these two cases, we estimate the differences in post-retirement wealth and the welfare gains potentially realizable if asset allocations were not subject to a homeownership constraint. For realistic parameter values, we find that the homeowner would require a substantial increase in total net worth to achieve the same level of utility as would be achievable if the choice of a home could be separated from the asset allocation decision. The robustness of the analysis is evaluated with respect to the model’s parameters and initial state variables. We find that changes in the values of the constraint (i.e., the value of the home) and the expected real rate of home value appreciation are the only state variables or parameter that is associated with a large change in asset allocation and/or the burden imposed by the housing constraint. This finding suggests the importance of a detailed examination of the impact of inter-regional differences in home prices and expected rates of appreciation on asset allocation and post-retirement wealth.     

How disclosure quality affects the level of information asymmetry

We examine two potential mechanisms through which disclosure quality is expected to reduce information asymmetry: (1) altering the trading incentives of informed and uninformed investors so that there is relatively less trading by privately informed investors, and (2) reducing the likelihood that investors discover and trade on private information. Our results indicate that the negative relation between disclosure quality and information asymmetry is primarily caused by the latter mechanism. While information asymmetry is negatively associated with the quality of the annual report and investor relations activities, it is positively associated with quarterly report disclosure quality. Additionally, we hypothesize and find that that the negative association between disclosure quality and information asymmetry is stronger in settings characterized by higher levels of firm-investor asymmetry.     

Multimarket trading and liquidity: a transaction data analysis of Canada–US interlistings

We use transaction data for Toronto Stock Exchange (TSE) listed stocks to examine the impact on trading costs of the decision to interlist on a US exchange. We measure trading costs using both ‘posted’ bid-ask spreads and ‘effective’ bid-ask spreads that measure actual transaction prices relative to standing bid-ask quotes. After controlling for price level, trade size and trading volume effects, we find that overall posted and effective spreads in the domestic (TSE) market decrease subsequent to the interlisting. However, the decrease in trading costs is concentrated in those TSE stocks that experience a significant shift of total trading volume (TSE and US) to the US exchange after listing. We interpret this result in the context of theories of multimarket trading as a competitive response by TSE market makers to the additional presence of US market makers.     

Regime-switching and interest rates in the European monetary system

This paper examines the impact that a currency target zone has on short-term interest rates. For a number of countries in the European Monetary System, we characterize the short rate using a regime-switching model that allows for a differently parameterized mean-reverting square-root process in each regime. We find that the volatility, the level, and the speed-of-adjustment are all higher in the regime that is operative during speculative attacks and currency crises. Moreover, we allow the conditional probability of being in each regime to be state-dependent so the model can be used to examine questions relating to the likelihood of realignments and the stability of the target zone system.
