Abstract . The George scholars today appear to be interesting the academic community in re-evaluating Henry George and his ideas. George, the 19th century American economist and social philosopher, dedicated himself to ending poverty by giving everyone equal access to the earth and its resources. He believed that land monopoly could be ended by taking the economic rent of all land and natural resources to meet the costs of government in lieu of taxes on labor and capital. George's writings revived interest in the ethos of the early settlers a time when sight was being lost of Pioneer America's contribution to the world's march toward freedom. 相似文献

This paper represents a theoretical investigation of profit maximizing behavior of a landlord under rent control. The situation envisioned is one that the landlord owns, free and clear, either two housing units ready to merge or one large one ready to convert into two small ones; in each case the units are already in place, such that capital costs are sunk and treated as bygones. Each unit has a technology of production of housing services with a fixed input of quantity of space (shelter) and a variable input of quality, that is affected by physical ageing (non-controllable) and by maintenance (controllable). At starting time t0, we have a state of quality and a historical state of initial quality Q?i, at the time the building was built, with the implicit constraint that Qi(t) < Q?i, for all t> t0. The analysis addresses the general question of housing structural changes—conversion or merger—and how these changes are being accelerated under the threat of rent control. 相似文献

This paper deals with the conflict between local and through traffic when allocating land for transportation at the expense of residential consumption. The model developed in this paper gives the optimal allocation of land between both uses, via Pontryagin's Maximum Principle, and shows the impact of through traffic on the urban structure, on local transportation costs and on the cost of housing supply. The cost functionals are used to measure the total burden to the inner city and a connection is made to the ongoing discussion of the ‘exploitation’ thesis. 相似文献

In order to fulfill their function as information intermediaries in capital markets, sell-side equity analysts regularly issue
updated forecasts on the stocks they cover. Quite often, the publication of (revised) analysts’ reports is subject to certain
trigger events such as the publication of annual figures or the announcement of an upcoming merger. In this exploratory study,
we develop a two-step procedure to identify the core events that trigger the release of analysts’ reports on companies that
constitute the Dow Jones EuroSTOXX50 index during the three-year period from 2004 to 2006. These can be grouped into Financial Disclosures, Corporate Management, Corporate Strategy, Business Activity, Operating Environment and Share. The results suggest that sell-side analysts attach great importance to non-financial information events when transforming
their earnings estimates into valuation forecasts and stock recommendations. Additionally, we link the information events
identified as reasons of issuance to the summary measures disclosed in the reports in order to investigate the relationship
between the report trigger and associated analyst reaction. Our findings indicate that the forecasting activity of sell-side
analysts is greatly influenced by forward-looking statements made by management, strategy-related news flow, and non-company-specific
information relating to the covered firm’s operating environment. 相似文献

This paper proposes the use of a portfolio optimization methodology which combines features of equilibrium models and investor’s views as in Black and Litterman (1992), and also deals with estimation risk as in Michaud (1998). In this way, our combined methodology is able to meet the needs of practitioners for stable and diversified portfolio allocations, while it is theoretically grounded on an equilibrium framework. We empirically test the methodology using a comprehensive sample of developed countries fixed income and equity indices, as well as sub-samples stratified by geographical region, time period, asset class and risk level. In general, our proposed combined methodology generates very competitive portfolios when compared to other methodologies, considering three evaluation dimensions: financial efficiency, diversification, and allocation stability. By generating financially efficient, stable, and diversified portfolio allocations, our methodology is suitable for long-term investors such as Central Banks and Sovereign Wealth Funds. 相似文献

Tests of the expectations hypothesis reveal that the slope of the VIX futures term structure predicts the direction but not the magnitude of the evolution of the short-end of the curve, but predicts neither the direction nor the magnitude of short-term changes in the long-end of the curve. Relative value seeking spread trades, constructed to exploit such violations, deliver excess returns with annualized Sharpe ratios equal or greater than those of volatility-writing strategies deployed by VIX ETN's for a majority of the 32 spread trade combinations tested. I demonstrate that profits from beta-neutral variations of the spread trades, which are not compensation for taking on equity downside risk by design, are propagated by inflows of capital into VIX futures markets, after controlling for factors that measure changes in the availability of hedge fund capital, risk appetite, and momentum. At the heart of profits, and by extension the term structure anomalies, is a disproportionally elevated basis propagated by long VIX demand that enters the futures market through ETN channels. 相似文献

AbstractDevelopment strategies followed by many countries in the 20th century bestowed a relevant role to the State. During the 1970s, it all reversed, and free markets became paramount to efficiency. F. von Hayek and the Mount Pelerin Society led the way to eliminate the State as a significant economic player, while P.T. Bauer extended such ideas to development economics, which would eventually give way to the Washington Consensus. Beyond actual results of such policies, it is surprising to see the appeal of Bauer’s theoretical approach, considering that it is constructed disregarding both empirical evidence, as well as the abundant discussion on development that was taking place contemporarily. This article explores the theoretical process of such reversal in development economics theory. 相似文献

This study analyzes the relationship between entrepreneurial dynamics in Latin-American countries and the level of competitiveness
these countries show. Based on the research conducted by Wennekers et al. [Small Business Economics, 24(3):293–309, 2005] that demonstrates a U-shaped relationship between the country’s rate of entrepreneurship and its level
of competitiveness and economic development, we hypothesize that Latin-American countries have a descending behaviour under
the U-shaped curve approach. The results from three regression models support this hypothesis and suggest that competitiveness
and economic growth deter entrepreneurial dynamics on Latin-American countries. We discuss that Latin-American countries need
to improve some structural factors to achieve a high level of entrepreneurial dynamics.

The present paper continues the firsts reviews made to socially responsible investment in Mexico. We extended these reviews by using a non-parametric multivariate equality test, along with a multi-factor market cap model, and a Monte Carlo simulation. Our results show that the IPCS index, the IPCcomp and the IPC have a statistically equal mean-variance performance, suggesting that this sort of investment style (SRI) is a good substitute of the broad market investment style in the long term. Among the causes of this finding is the fact that the IPCS and the IPCcomp indexes have almost the same large and small cap stock concentration and the IPC index (a large-cap one) is not as diversified and mean-variance efficient as the former. 相似文献

The aim of this paper is to evaluate how immigration of high-skilled workers affects the technological-knowledge bias and, in turn, the skill premium in the host countries, in particular bearing in mind the recent experience in a number of European countries. We study a skill-biased dynamic general equilibrium R&D growth model in which the standard R&D technology is modified so wage inequality results from the direction of the technological knowledge, which in turn is induced by the price channel. By solving the transitional dynamics numerically, we show that the rise of the skill premium arises from the price-channel effect, complemented with a mechanism that reflects the impact of immigration on R&D. According to our quantitative results, our model is able to account for a significant proportion of the dynamics of the skill premium in the data for a number of European countries, thus, suggesting that differences in labour skills between immigrants and natives are, in practice, an important source of skill premium variation over time. 相似文献
