Factor Price Equalization : Geometrical Conditions

This paper presents a geometrical approach to the univalence problem for a system of cost functions. We present a natural (almost tautological) extension of a geometrical theorem due to McKenzie: our sufficient condition is related to the non-separability of two cones formed by convex combinations of the rows of the Jacobian matrix. This means that the cones spanned by the rows of Jacobian matrix (i.e., production coefficients) do not move wildly so that the two cones corresponding to the two end points (i.e., factor price vectors) cannot be separated by the hyperplane orthogonal to the vector of changes in factor prices. Unlike most ofthe previous propositions, our condition can naturally include as a special case such linear systems as having a non-singular matrix. We also give an alternative condition employing the concept of monotone functions. Dual to the above result is one more condition, which is shown to be closely connected with Kuhn's WARP-like requirement when the given functions are concave as well as homogeneous of degree one

Petrology and tectonic development of supracrustal sequence of Kerala Khondalite Belt, Southern India

The granulite terrain of southern India, of which the Kerala Khondalite belt (KKB) is a part, is unique in exposing crustal sections with arrested charnockite growth in different stages of transformation and in varied lithological association. The KKB with rocks of surficial origin and incipient charnockite development, poses several problems relating to the tectonics of burial of vast area and mechanisms involved in expelling initial H2O (causes of dryness) for granulite facies metamorphism. It is possible to infer the following sequence of events based on the field and laboratory studies: (1) derivation of protoliths of KKB from granitic uplands and deposition in fault bounded basin (cratonic rift); (2) subhorizontal deep burial of sediments; (3) intense deformation of infra and supracrustal rocks; (4) early granulite facies metamorphism predating F sub 2 - loss of primary structure in sediments and formation of charnockites from amphibole bearing gneisses and khondalites from pelites; (5) migmatisation and deformation of metasediments and gneisses; (6) second event of charnockite formation probably aided by internal CO2 build-up; and (7) isothermal uplift, entrapment of late CO2 and mixed CO2-H2O fluids, formation of second generation cordierites and cordierite symplectites

Teaching And Research Interests In Real Estate

This paper presents the findings of an investigation aimed at determining teaching and research interests of U.S. finance faculty regarding the academic discipline of real estate.  The paper focuses on two groups of finance faculty from six academic years spanning the 1994-2005 period.  While one group consists of an exhaustive roster of titled professors of finance as per the Hasselback directories, the other consists of randomly selected samples of finance educators from over 800 U.S. colleges and universities.  On average, about 1 in 14 titled professors and 1 and 13 randomly selected finance professors had noted real estate as an area of teaching interest.  Approximately 5 percent of all reported teaching interests were in real estate for both groups of faculty.  The study also reveals that about 1 in 11 titled professors and 1 in 12 sampled faculty had an interest in conducting research in the real estate field.  Among the randomly selected finance faculty who wanted to teach or perform research in real estate, less than 20 percent were assistant professors, 30 percent were associate professors and more than 40 percent were full professors

Agent Based Modeling of Electronic Markets To Analyze the Sustainability of Mutual Cooperation

According to game theory, dominant strategy of Prisoner’s Dilemma game is defecting. Since online trading between two strangers falls in the realm of a Prisoner’s Dilemma, failure should be the only logical conclusion of such electronic commerce situation. Traders are less likely to cooperate since they are not required to deal with the same buyer again given the enormous population of online traders. Thus one could argue that markets like eBay should never exist. Then what is the reason behind resounding success of such electronic markets? The answer lies in the reputation system that they established. Google page rankings and reader reviews on various sites like Amazon.com and Epinions.com are some other examples of the reputation system pointing towards the enormous influence that they wield in our everyday life. This research thus attempts to analyze importance of reputation system in an online trading using Agent Based Simulation. The effect of reputation system on the sustainability of mutual cooperation between online traders is analyzed by taking into account key factors like level of gullibility of online traders and the weight of influence given to their past behavior. Results indicate that reputation system is certainly capable of sustaining cooperation among online traders. However, weightage given to the past behavior of agents should be decided only after taking into account the level of gullibility of agents. Use of agent based modeling for studying dynamics of online trading is a relatively new concept. Sustaining cooperation among online traders is often perceived to be difficult task. The reputation system proposed in this research is expected to make contribution towards this goal

The Price-Volume Relationship In The Chilean Stock Market

This study focuses on the econometric relations between daily returns and daily trading volume changes on the Santiago Stock Exchange of Chile. To meet this task, the study utilizes the data of the Selective Stock Price Index, IPSA, from January, 2003 through October, 2006. A significant contemporaneous relation is found between volume and returns. The evidence also indicates that the said relation is asymmetric. Moreover, the results support the notion that the trading volume makes the market move. The causality test results provide a clear evidence of daily returns Granger causing daily trading volume changes in the Chilean equity market

Water activities in the Kerala Khondalite Belt

The author and colleagues presented their determinations of water activities in various granulite-facies rocks of the Kerala Khondalite Belt. Using mineral equilibria, thermodynamic data, and assumed geopressure-geotemperature conditions of 5.5 kbar and 750 C, they calculated uniformly low a(H2O) values of about 0.27 over a large geographic region. They suggested that these conditions were produced by the presence of abundant CO2-rich fluids, derived either from deeper levels or from metamorphic reactions involving graphite

Chinese tourist numbers in Sri Lanka: a case for improving growth

Despite the growth in Sri Lanka's tourism industry fuelled by increasing tourist arrivals from China since 2009, the number of Chinese tourists remains negligible when compared to the numbers of Chinese tourists travelling to other countries. Sri Lanka can and should take concrete steps to multiply its incoming tourists from China. N.R Ravindra Deyshappriya writes
