the demand for money in developing countries assessing the role of financial innovation traditional specifications of money demand have commonly been plagued by persistent overprediction implausible parameter estimates and highly autocorrelated errors the authors argue that some of these problems stem from the failure to account for the impact of financial innovation they estimate money demand for ten developing countries using various proxies for financial innovations they also assess the relative importance of this variable finding financial innovation can be better modeled as a stochastic random walk trend rather than a deterministic time trend financial innovation plays an important role in determining fluctuations of the demand for money the importance of this role increases with the rate of inflation

firms as portfolios a mean variance analysis of unquoted uk companies this paper adopts a mean variance portfolio framework to model the balance sheet behavior of unquoted companies with respect to choice items such as fixed investment investment in stocks trade credit and borrowing econometric results for a sample of thirty nine u k firms are consistent with many of the restrictions implied by portfolio theory in particular that these balance sheet items are jointly determined copyright 1989 by blackwell publishing ltd

neoclassical consumer demand theory and the demand for money m friedman 1956 suggests that the demand for money should be analyzed in terms of consumer demand theory although often the interpretation of empirical results from studies using aggregate data appears to be in terms of the motives approach i e transactions precautionary and speculative motives the authors develop friedman s ideas within an explicit model of consumer theory and find that they provide a consistent framework for analyzing portfolio choice and offer greater insights into results from aggregate studies of the demand for money than the motives approach in particular the authors provide a new interpretation of the role of nominal interest rates inflation and a hicksian measure of wealth in the demand for money function copyright 1991 by royal economic society

modelling money demand in open economies the case of selected asian countries while early work on money demand estimation focused primarily on the importance of domestic variables many studies in later years have suggested that foreign variables also influence the domestic demand for money in an open economy with the rapid financial market liberalization in some of the asian economies in the last couple of decades open economy factors have become very important in the determination of money demand therefore this paper aims to ascertain the degree to which foreign opportunity cost variables influence money demand in the philippines singapore and south korea cointegration analysis is performed and an error correction model estimated using quarterly time series data the empirical results support the inclusion of foreign opportunity cost variables in the money demand function

portfolio behaviour in a flow of funds model for the household sector in india we estimate a flow of funds model for the household sector in india within the almost ideal demand system aids framework and examine the demand for money and the substitution effects between money and other financial assets the restricted long run model obtained using cointegration techniques provides stable equilibrium relationship between i 1 variables and broadly satisfies the axioms of rational choice in consumer demand theory we find that financial sector reform exerts a significant impact on the interest rate structure and household portfolio preferences specifically there is strong substitutability among risk free assets and a possible speculative effect in the stock market while the exchange rate strongly influences the demand for money these findings all have important policy implications

genetic algorithm evolution of utility bidding strategies for the competitive marketplace this paper describes an environment in which distribution companies discos and generation companies gencos buy and sell power via double auctions implemented in a regional commodity exchange the electric utilities profits depend on the implementation of a successful bidding strategy in this research a genetic algorithm evolves bidding strategies as gencos and discos trade power a framework in which bidding strategies may be tested and modified is presented this simulated electric commodity exchange can be used offline to predict whether bid strategies will be profitable and successful it can also be used to experimentally verify how bidding behavior affects the competitive electric marketplace

the financial structure and the demand for money in thailand this paper uses recently developed econometric techniques to investigate the demand for money in thailand initial estimates show the absence of any long term unique relationship among a monetary aggregate m1 or m2 an income and a price variable however the introduction of an exchange rate in the above relationship shows the presence of a cointegrating relationship this provides some support to mckinnon s hypothesis of currency substitution it also raises some concern about the closed economy focus of earlier studies on money demand in thailand addition of a foreign interest variable to the above models provide some support to the capital mobility hypothesis the long run elasticity estimates for the m1 equation raise some doubts about the desirability of using this monetary aggregate as an intermediate target by the bank of thailand the null hypothesis of a unit income elasticity and zero foreign interest elasticity are not rejected but the hypothesis of price homogeneity is rejected moreover

money demand in china in the reform period an error correction model based on integration and cointegration test findings this paper constructs an error correction ecm model to evaluate the dynamic adjustment process of money demand in china in the reform period 1979 to 1990 the cointegration tests suggest that some long run relationship exists among money demand real income price and the real interest rate the ecm model shows that the dynamic adjustment process of money demand maintains stable and significant relationships to most of its determinants

financial liberalization in india and a new test of the complementarity hypothesis abstract this article reappraises the financial repression hypothesis for india in light of the partial liberalization of the financial sector in the early 1990s using for the first time state of the art multivariate cointegration and vector error correction models vecm from this more robust testing procedure we find that for the indian economy over the sample period 1951 99 money and capital are complementary suggesting that higher real interest rates will further raise the demand for money and lead to higher levels of investment furthermore testing for a structural break in the early 1990s to coincide with the liberalization of the financial sector in india suggests that these reforms have not significantly changed the complementary relationship between money and capital the policy implication is that further financial liberalization maybe required in india to enhance investment and economic growth

asset portfolios and credit rationing evidence from kenya this paper presents a model of the private sector s demand for financial and real assets in kenya for the period 1973 90 the private sector is assumed to hold its wealth in terms of five assets but is quantity rationed in the credit market the model is estimated as a co integrated demand system based on the almost ideal demand system of deaton and muellbauer 1980 the model highlights the role of real asset accumulation in offering a hedge against inflation and the role of credit rationing in the composition of wealth asset markets in developing countries and particularly those of sub saharan africa have typically been subject to controls on prices through interest rate controls and quantities through credit rationing it is natural to ask how these controls affect the level composition and evolution of private sector wealth for example how does the wealth portfolio respond to changes in the level of credit rationing how do controls on nominal interest rates determine the private sector s response to inflation since these questions are not readily addressed using conventional single equation models of money demand this paper examines them within a more general model of portfolio choice in which relative asset price effects and quantity rationing in the market for domestic credit are made explicit the econometric model which is similar to that of taylor and clements 1983 perraudin 1987 and barr and cuthbertson 1991 1992 1994 is based on a dynamic representation of the almost ideal demand system adapted to handle rationing using aggregate time series data for kenya the model characterizes the asset portfolio chosen by a representative private sec tor agent facing a two stage budgeting problem in the first stage the represen tative agent chooses his or her labour supply and consumption and hence the net addition to wealth at the second stage the new stock of wealth adjusted for capital and exchange rate gains or losses is allocated across different assets which in this case consist of money bank deposits and loans the latter being treated as negative assets real assets in the form of equity claims and govern ment securities the demand shares for the components of the portfolio are then estimated within an error correction system of equations the model is estimated on quarterly data for the period 1973 90 2 there are a number of reasons for adopting this particular approach first and most obviously the demand system provides for a more comprehensive description of the evolution of the overall portfolio composition than is poss ible using traditional single equation approaches this is particularly true in

thermal power generation scheduling by simulated competition this paper presents a new method for solving the unit commitment problem by simulation of a competitive market where power is traded through a power exchange px procedures for bidding and market clearing are described the market clearing process handles the spinning reserve requirements and power balance simultaneously the method is used on a standard unit commitment problem with minimum up down times start up costs and spinning reserve requirement taken into account comparisons with solutions provided by lagrangian relaxation genetic algorithms and chao an li s unit decommitment procedure demonstrate the potential benefits of this new method the motivation for this work was to design a competitive electricity market suitable for thermal generation scheduling however performance in simulations of the proposed market has been so good that it is presented here as a solving technique for the unit commitment problem

the role of economic theory in modelling the long run this argues for a closer link between the modelling of the long run relations in applied economics and the intertemporal equilibrium notion from economic theory this abstract was borrowed from another version of this item

demand for money in sri lanka during the post 1977 period a cointegration and error correction analysis this paper investigates the long run demand for money and short run dynamics of the long run money demand function for sri lanka during the post 1977 period while m1 is cointegrated with real income nominal interest rate short term foreign interest rate and real effective exchange rate m2 is not this suggests that monetary authorities should emphasize the narrow definition of money for monetary control the one year fixed deposits rate is cointegrated with m1 indicating the opportunity cost of holding money although the inflation rate is not cointegrated with m1 it seems to be an important determinant of the demand for m1 in the short run results also suggest that the short term foreign interest rate and the exchange rate can have important implications for the effectiveness of monetary policy monetary authorities must consider the response of domestic money demand to these external factors when formulating future monetary policies

demand for money in bangladesh a cointegration analysis the aim of this study is to estimate the demand for real broad m2 money in bangladesh using the most recently developed autoregressive distributed lag approach to cointegration analyses the empirical results show that there is a unique cointegrated and stable long run relationship among real per capita broad money demand real per capita income domestic interest rates and unofficial exchange rate um premiums which act as a surrogate for foreign interest rates with money as the dependent variable the results show that the income and interest elasticities are positive while the um premium elasticity is negative these results suggest that distortions in the financial and foreign exchange markets should be reduced in order to increase financial saving or monetary accumulation our results also reveal that the demand for money in bangladesh is stable despite the changes in financial and exchange rate policies between 1975 and 1995

a re examination of the demand for money in small developing economies this paper re examines the money demand function in three small open economies of asia korea pakistan and singapore in addition to using the relatively new procedure of error correction modelling the roles of variables such as a the expected change in the exchange rate b foregin interest rates and c foreign exchange risks on money demand are examined in testing the importance of these variables in the money demand function special attention is paid to testing the assumptions of the classical linear regression model the sample period for each country spans from 1973 1 through 1990 1 the empirical results suggest that the error correction specification performs very well in addition to the traditional variables the results suggest that at least some measure of foreign monetary developments appear to have some significant effect on money demand behaviour in these small developing economies

price taker bidding strategy under price uncertainty this paper provides a framework to obtain the optimal bidding strategy of a price taker producer an appropriate forecasting tool is used to estimate the probability density functions of next day hourly market clearing prices this probabilistic information is used to formulate a self scheduling profit maximization problem that is solved taking advantage of its particular structure the solution of this problem allows deriving a simple yet informed bidding rule results from a realistic case study are discussed in detail

exchange rate sensitivity of demand for money and effectiveness of fiscal and monetary policies one of the arguments between proponents and opponents of floating exchange rates centres around the relative effectiveness of fiscal and monetary policy while proponents of floating rates argue that monetary policy is more effective under floating rates its opponents contend that fiscal policy is more effective under fixed rates however economic theory suggests that there is room for both policies under both types of exchange rate system depending upon degree of sterlization concentrating on the floating rates mundell 1963 has argued that the relative effectiveness of monetary and fiscal policies would also depend upon sensitivity of money demand to exchange rate more precisely he has conjectured that the demand for money is likely to depend upon the exchange rate in addition to the interest rate and the level of income this would slightly reduce the effectiveness of a given change in the quantity of money and slightly increase the effectiveness of fiscal policy on income and employment under

strategic bidding in an energy brokerage this focus of this paper is to present a framework in which strategies may developed for the individual participants in an energy brokerage such a framework is expected to be important with the increasing interest in electricity market structures such as the energy brokerage that deregulation has produced to illustrate the process of strategic bidding a simple suboptimal bidding strategy is presented with the aid of a numerical example the bidding strategy must be suboptimal because of the amount of unknown information about the other bidders further tuning of this strategy will be required before application to realistic scenarios

tanzanian formal sector workers participation in informal production a theoretical model is developed explaining formal sector workers participation in the informal sector a reduced form informal sector participation function is derived from a specific utility function a specific informal sector production function and a specific informal sector earnings function the participation function can be estimated consistently and provides a solution to the problem that informal sector wages in developing countries are hard to observe a sample of tanzanian formal sector workers is used to estimate the participation function a majority of tanzanian formal sector workers participate in informal production participation in informal production is inversely related to household income to living in dar es salaam and to being a mother with small children participation is positively related to age and multiple job holding seems to play a very different role in the transition from work to retirement in tanzania compared to industrialized countries

a simulation model for a competitive generation market the simulation of a wholesale electricity market should go beyond a simple optimization based on the operating costs of the generating units a model of a competitive electricity market must consider the market structure the strategy of the market participants and any other factor that lead to prices different from costs this paper presents cosmee a model of a wholesale electricity market based on simple bids that estimates expected bid prices and quantities system hourly prices and generation schedules taking into account the bidding strategies of generators and the structure of the market the model reflects the profit maximizing behavior of the market agents subject to different types of constraints cosmee has been used to simulate a real wholesale market
