The classical warrant pricing formula requires knowledge of the firm value and of the firm‐value process variance. When warrants are outstanding, the firm value itself is a function of the warrant price. Firm value and firm‐value variance are then unobservable variables. I develop an algorithm for pricing warrants using stock prices, an observable variable, and stock return variance. The method also enables estimation of firm‐value variance. A proof of existence of the solution is provided. 相似文献

This paper is devoted to studying optimal designs for estimating an extremal point of a multivariate quadratic regression model in the unit hyperball. The problem of estimating an extremal point is reduced to that of estimating certain parameters of a corresponding nonlinear (in parameters) regression model. For this reduced problem truncated locally D-optimal designs are found in an explicit form. The result is a generalization of the results of Fedorov and Müller (1997) for onedimensional quadratic regression function in the unit segment.

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. 相似文献

We examine transfers from Russia’s federal government to the regions during the two recent economic crises. We show that while federal transfers in 2009 were large and targeted poorer regions, the 2014–2015 transfers were much smaller and not targeted. This policy shift was accompanied by a relatively greater decline in own revenues in the poorer regions and their worse economic performance overall. As a result, interregional budget expenditure inequality in Russia was significantly higher in 2014–2015 than it had been for years. This is important because regional budgets are responsible for a large share of investments, housing, education and healthcare. 相似文献

This study explores whether automobile travel during inclement weather has become more or less risky over the past two decades. The analysis is based on the integration of two government databases and a matched-pair framework for comparing casualty rates under different weather conditions for 10 Canadian cities. The most notable result is a downward trend in relative risk during rainfall from 1984 to 2002 – both overall and when further disaggregated by injury severity combined with precipitation amount, city group, and time of day. By contrast, the overall relative risk of casualty during snowfall shows no significant change over time. 相似文献

This article presents the results of the system dynamics modelling of the regional market of health tourism in the Krasnodar region of Russia. The research was based on various indicators characterizing the supply and demand for this type of tourism for years 2006–2012. The medium-term forecast made by constructed model shows a possible decrease in number of health tourists and income of sanatorium organizations. Price competition of inexpensive foreign resorts was a key factor influencing the market of tourist services; therefore ruble devaluation to US dollar may improve the prognostic indicators. 相似文献

This article establishes a theoretical and empirical link between the use of aggressive mortgage lending instruments, such as interest‐only, negative‐amortization or subprime mortgages, and the underlying house prices. Such instruments, which come into existence through innovation or financial deregulation, allow more borrowing than otherwise would occur in previously affordability‐constrained markets. Within the context of a model with an endogenous rent‐buy decision, we demonstrate that the supply of aggressive lending instruments temporarily increases the asset prices in the underlying market because agents find it more attractive to own or because their borrowing constraint is relaxed, or both. This result implies that the availability of aggressive mortgage lending instruments magnifies the real estate cycle and the effects of fundamental demand shocks. We empirically confirm the predictions of the model using recent subprime origination experience. In particular, we find that regions that receive a high concentration of aggressive lending instruments experience larger price increases and subsequent declines than areas with low concentration of such instruments. This result holds in the presence of various controls and instrumental variables. 相似文献

We use a mean-variance approach to address the classic puzzle of British capital export in the 19th century. Our analysis
shows that foreign securities listed in London offered significant diversification benefits to British investors. In simple
terms, international diversification reduced risk. Conservative estimates of the optimal investment portfolio for a domestic
investor suggest that the balance between foreign and domestic security offerings on the London Exchange was close to what
classic equilibrium models of asset prices would suggest.

The ongoing global financial crisis has led to the largest increase in state intervention since the Great Depression. Direct government ownership in publicly-traded corporations has increased dramatically since 2008. How will this increase in public ownership affect the governance of these erstwhile private companies? We examine the impact of government ownership on corporate governance using a sample of firms from the European Union, a region that is relatively familiar with active government participation. Our main finding is that government ownership is associated with lower governance quality. We further show that while government intervention is negatively related to governance quality in civil law countries, it is positively related to governance quality in common law countries. Finally, we find that the preferential voting rights of golden shares are especially damaging to governance quality. 相似文献
