Skyscrapers are an intellectual challenge for urban analysis because of their imposing visual presence in the city landscape, and because of their environmental and real estate impacts. These characteristics however have not received much attention in the literature, particularly in analyses about Latin American cities. In this paper, we describe and test four theories about record-breaking buildings height: traditional microeconomic theory, game theory, business cycle, and global cities. We use a 2000–2012 panel database of 29 cities from 10 different Latin American countries, in order to contrast the contesting explanations about buildings’ height. We design a baseline model and then, using four different estimation techniques and diverse specifications, find that traditional theory and more strongly, global cities are good predictors of buildings’ height. 相似文献

Under the general affine jump-diffusion framework of Duffie et al. [Econometrica, 2000, 68, 1343–1376], this paper proposes an alternative pricing methodology for European-style forward start options that does not require any parallel optimization routine to ensure square integrability. Therefore, the proposed methodology is shown to possess a better accuracy–efficiency trade-off than the usual and more general approach initiated by Hong [Forward Smile and Derivative Pricing. Working paper, UBS, 2004] that is based on the knowledge of the forward characteristic function. Explicit pricing solutions are also offered under the nested jump-diffusion setting proposed by Bakshi et al. [J. Finance, 1997, 52, 2003–2049], which accommodates stochastic volatility and stochastic interest rates, and different integration schemes are numerically tested. 相似文献

Since the mid‐1990s the banking sector in the Latin American emerging markets has experienced profound changes due to financial liberalization, a significant increase in foreign investments, and greater merger activities often occurring following financial crises. The wave of consolidation and the rapid increase in market concentration that took place in most countries has generated concerns about the rise in banks' market power and its potential effects on consumers. This paper advances the existing literature by testing the market power (Structure–Conduct–Performance and Relative Market Power) and efficient structure (X‐ and scale efficiency) hypotheses for a sample of over 2500 bank observations in nine Latin American countries over 1997–2005. We use the Data Envelopment Analysis technique to obtain reliable efficiency measures. We produce evidence supporting the efficient structure hypotheses. The findings are particularly robust for the largest banking markets in the region, namely Brazil, Argentina, and Chile. Finally, capital ratios and bank size seem to be among the most important factors in explaining higher than normal profits for Latin American banks. 相似文献

Consumers’ perception of, and satisfaction with, fruit quality is an important issue for both public policy and commercial reasons. However, because of information problems, consumers cannot easily choose fruits of a quality most likely to satisfy their preferences and health needs. The research reported here employed an experimental auction method to test perceptions of fruit quality by evaluating the willingness to pay (WTP) of consumers for five different varieties of soft citrus under three different information conditions: visual inspection of the fruit before peeling; visual inspection after peeling; and after consumption. Significant differences were found in valuations of the different varieties as consumers gained information. Conclusions are drawn about the value of the methodology and the results themselves, and implications are inferred for policy and for growers and traders. It is argued that product information should be oriented not just towards nutritional education but also towards increasing the pleasure of healthy eating. 相似文献

This paper studies the pattern of capital mobility within atwo-country dynastic model in which each country is exogenouslycharacterized by its degree of altruism toward children. Thesteady-state welfare implications of restricted as well as unrestrictedcapital mobility are established. It is shown that world integrationincreases the steady-state welfare of the more altruistic capitalexporting country and can either increase or reduce the steady-statewelfare of the less altruistic capital importing country. 相似文献

Perceived insecurity in the public space: Personal, social and environmental variables. This paper explores perception of
insecurity among the users of Barcelona’s public space. It describes the results of a research aimed to determine the key
variables for the understanding of subjective insecurity. Structural equation models have been applied for this purpose. Results
show low relative indices of causality for environmental variables, whereas those related to space representation, residential
satisfaction and urban identity, social support and personal competences offer high predictive potential. It is concluded
that insecurity perceptions in the public space are therefore strongly linked to social interaction processes and to the social
construction of insecurity. Other results, like the influence of gender or age, are consistent with previous findings. 相似文献

A new characterization of the American-style option is proposed under a very general multifactor Markovian and diffusion framework.
The efficiency of the proposed pricing solutions is shown to depend only on the use of a viable valuation method for the corresponding
European-style option and for the transition density of the model’s state variables. Under a Gauss-Markov stochastic interest
rates setup, these new American option pricing solutions are shown to offer a much better accuracy-efficiency trade-off than
the approximations already available in the literature. This result is also used to price callable corporate bonds under an
endogenous bankruptcy structural approach, by decomposing the option to call or default into a European put on the firm value
plus two early exercise premium components. 相似文献
