Abstract Driven by fast evolution in the money market during the past two decades, financial and technological innovations, increasing competition, and internationalizing of businesses, cash and treasury management has become an increasingly important function in most firms. It is reasonable to expect that the role of financial transactions in the cash management process in adding to firm value has increased its importance and changed the cash management behavior of firms. The main purpose of this study is to investigate this potential behavioral change in cash management by examining the cash management practices behind the models explaining the cash management behavior and to test the stability of some of these models. It is hypothesized that the environmental changes have been remarkable enough to change the cash management behavior, which can be seen as a structural change in the cash management function. The factors assumed to explain this phenomenon may concern organizational and technological arrangements in cash management, likewise professional skills in the area of financial transactions and incentives for these especially created by emerging money markets. The examination was conducted using the survey method to map out the best cash management practices followed by Finnish listed manufacturing and service companies and by testing the stability of both static and dynamic models explaining cash management behavior. The empirical part of the study is based on three questionnaires in three separate years, namely 1988, 1994, and 2000, and the empirical estimation of the selected cash management models using financial statement data for the years 1972 to 2001. The study concludes that during the research period firms have achieved a significant technological progress (improving systems and methods) and significant behavioral changes (increasing professionalism) concerning cash management practices, referring to opportunities for more effective cash management operations. The stability tests of cash management models indicated that a structural change in cash management behavior occurred after the deregulation years in the money market. These results were consistent with the surveys referring the development in the efficiency of the firms' cash management.

There has been extensive theoretical and empirical research on the subject of demand for money function. This particularly stems from the important role demand for money plays in macroeconomic analysis, especially in the design and implementation of monetary policy. The increase in studies, especially in developing countries, can also be attributed to a number of factors like: the impact of moving towards flexible exchange rate regimes, globalisation of financial markets, ongoing financial liberalisation, innovations in domestic financial products, the advancement in econometrics techniques and other country-specific events. This study estimates and examines the nature and stability of the demand for broad money (M2) in Botswana. This is particularly important in that the usefulness of a money demand function in the conduct of monetary policy depends crucially on its stability. The stability of the money demand function is crucial in that a stable money demand function would mean that the quantity of money is predictably related to a set of key economic variables linking money and the real economic sector. Therefore, this will help central banks to select appropriate monetary policy actions. Based on the findings, the study also proposes policy interventions. The vast majority of the literature on demand for money has underscored the fact that variable selection and representation, and the framework chosen are the two major issues relevant to modelling and estimation of the demand for money function. In modelling and estimating the demand for money function in Botswana, this study surveys a stream of theoretical and empirical literature on money demand in developed and developing countries, including countries that have similar financial sector similar to Botswana. Due consideration is also given to the macroeconomic and financial sector development in Botswana to help in the identification of the variables that are included in the demand for money equation. Most importantly, this helped in getting meaningful results that are free from theoretical and estimation problems. In particular, this study applied the multivariate cointegration approach as proposed by Johansen (1988) and Johansen and Juselius (1990) to estimate the relationship between broad money (M2), real income, interest rate, South African treasury bill rate, inflation rate and US dollar/pula bilateral exchange rate. The study obtains one unique long run relationship between money and the scale and opportunity cost variables. The coefficients of the long run relationship are then modelled along the general to specific approach as proposed by Campos, Ericsson and Hendry (2005). In this type of approach the general model is reduced by sequential elimination of statistically insignificant variables and checking the validity of the reductions at every stage to ensure congruence of the finally selected parsimonious model. In accordance with the economic quantity theory of money, the long run income elasticity obtained is 0.8021, which is close to the value one (unitary) suggested by economic theory. The coefficients of real income, exchange and inflation rate have the expected positive signs and were significant in the long run. Therefore, the long run demand for money (M2) in Botswana was found to be positively affected by real income, inflation rate and exchange rate. The lack of statistical significant of the own rate of money (88 day commercial bank deposit rate) and the foreign opportunity cost variable (South African Treasury bill rate) is attributed to multi-collinearity problems between these two interest rates. This could be caused by the fact that short term rates in Botswana are very responsive to movements in the money markets rates in South Africa. The short run dynamics of the demand for money function shows the slow speed of adjustment to equilibrium of about 2.9 percent in the first quarter and this is reflective of the lack of sufficient availability of banking services and the low returns on financial assets which could allow economic agents to re-establish equilibrium levels of money holdings faster. The final parsimonious model obtained clearly reflects a well specified stable demand for money function. Therefore, based on the findings we can be precise in stating that targeting a monetary aggregate can be a viable policy for the monetary authorities in Botswana.

Dissertation (PhD)--Stellenbosch University, 2003. / ENGLISH ABSTRACT: The endogenous money theory states that the money supply responds endogenously to the demand for credit. The money supply is not exogenously determined by the central bank. The endogenous theory is associated with the Post Keynesian school. It has been tested extensively for developed countries, where it was found that the modern credit-driven world is characterised by an endogenous money supply. The contribution of the present study is to extend this analysis to developing countries, specifically twelve countries in the SADC region. To examine the applicability of the endogenous money theory to developing countries, the thesis begins with an overview of the views of the different schools of thought on the role of money. The areas of consensus and disagreement within the Post Keynesian school are discussed. The theoretical basis of the thesis is the ‘structuralist’ Post Keynesian view that money cannot be endogenous if the financial system in a country has not reached the final stages of development. The ‘structuralist’ hypothesis is tested for the SADC countries by examining the demand and supply of credit money in each country. It was found that households do not generally have full access to formal credit markets. Changes in the money supply are not determined by changes in private sector credit in many of the countries. The analysis was then extended to the institutional environment in each country. A financial institutional index was developed to facilitate comparison between the SADC countries. It was shown that South Africa is the only country in the SADC area that has a financial system that can be classified as ‘largely developed’. It is also the only country where changes in the supply of money are predominantly credit-driven. Post Keynesians maintain that the money supply is endogenous and interest rates are exogenous. Interest rate mark-ups and spreads are assumed stable over the business cycle. This notion is challenged by the ‘structuralist’ Post Keynesians. To test the theory of stable interest rate mark-ups and spreads, data for each individual country were examined. Neither interest rate spreads, nor interest rate mark-ups were found to be stable. Interest rate spreads are generally higher in developing countries than in developed countries. No clear pro- or counter-cyclical variation in spreads was found. Finally, an econometric model was developed and the links between financial development and growth were examined. By looking at 49 developed and developing countries, it was found that financial development is strongly linked to economic growth. Financial repression and high interest rate spreads cause growth to be depressed. Financial development and increased competition in the banking sector will lead to higher real economic growth rates. In an environment where the financial system has not reached the stage where money is endogenous, the lack of financial institutional development stifles economic growth. / AFRIKAANSE OPSOMMING: Die teorie van ‘n endogene geldvoorraad aanvaar dat die aanbod van geld endogeen reageerop die vraag na krediet. Die geldvoorraad word nie eksogeen bepaal deurdie sentrale bank nie. Die endogene gedvoorraad teorie word geassosieer met die Post Keynesiaanse skool. Dit is reeds getoets vir ontwikkelde lande, waar die bevinding was dat ‘n endogene geldvoorraad ‘n eienskap is van ‘n moderne kredietgedrewe wereld. Hierdie tesis maak ‘n bydrae deur die analise uit te brei na ontwikkelende lande, spesifiek twaalf lande in die SADC streek. Om die toepasbaarheid van die endogene geldvoorraad vir ontwikkelende lande te toets, begin die tesis met ‘n oorsig van die verskillende denkskole se sienings oor die rol van geld. Die areas waar Post Keynesiane ooreenstem en verskil word bespreek. Die teoretiese basis van die tesis is die ‘strukturalistiese’ Post Keynesiaanse siening dat die geldvoorraad nie endogeen kan wees indien die finansiele sisteem in ‘n land nog nie die finale ontwikkelingstadia bereik het nie. Hierdie hipotese van die ‘strukturaliste’ word getoets vir die SADC lande deur te kyk na die vraag na en aanbod van krediet in elke land. Daar is bevind dat huishoudings oor die algemeen nie volledige toegang het tot formele kredietmarkte nie. Veranderinge in die geldvoorraad word nie in al die lande veroorsaak deur veranderinge in privaat sektor kredietverlening nie. Hierdie analise word dan uitgebrei na die institusionele omgewing in elke land, ‘n Finansiele institusionele indeks is ontwikkel om vergelyking tussen die SADC lande moontlik te maak. Daar is bevind dat Suid Afrika die enigste land is met 'n finansiele sisteem wat geklassifiseer kan word as ‘grotendeels ontwikkeld’. Dit is ook die enigste land waardie geldvoorraad beduidend kredietgedrewe is. Post Keynesiane glo dat die geldvoorraad endogeen is en rentekoerse eksogeen. Rentekoersmarges word gesien as stabiel oor die konjunktuursiklus. Hierdie aanname word bevraagteken deur die ‘strukturalistiese’ Post Keynesiane. Die teorie van stabiele rentekoersmarges word getoets deur te kyk na data vir elke individuele land. Die bevinding is dat rentekoersmarges nie stabiel is nie. Marges is oor die algemeen hoer in ontwikkelende lande as in ontwikkelde lande. Daar is geen duidelike pro- of kontrasikliese variasies in rentekoersmarges gevind nie. Laastens is ‘n ekonometriese model ontwikkel om die skakels tussen finansiele ontwikkeling en groei te ondersoek. Deur te kyk na 49 ontwikkelde en onontwikkelde lande, is daar bevind dat finansiele ontwikkeling en groei ‘n sterk verband toon. Finansiele onderdrukking en hoe rentekoersmarges lei tot laer ekonomiese groei. Finansiele ontwikkeling en groter mededinging in die bank sektor sal lei tot hoer reele ekonomiese groeikoerse. In ‘n omgewing waar die finansiele sisteem nog nie die stadium bereik het waar geld endogeen is nie, sal die gebrek aan finansiele institusionele ontwikkeling ekonomiese groei benadeel.

A especificação adotada é a de Tourinho (1995), que generaliza a de Cagan (1956) para permitir uma forma funcional mais flexível e incorporar outras variáveis, além da inflação esperada, como variáveis explicativas. Verifica-se que estas extensões são importantes para modelar a demanda por saldos monetários reais no período aqui considerado. A forma funcional semi-log de Cagan é rejeitada, em favor de uma forma funcional flexível Box-Cox, e os coeficientes da taxa de juros real e da variância da inflação são significativos, mostrando a importância destas variáveis serem inseridas ao modelo. A função estimada para o período completo é comparada com aquelas estimadas para os sub-periodos de inflação alta e moderada, para verificar a estabilidade da formulação adotada. Conclui-se que se pode rejeitar a hipótese de que ela é estável. O modelo de Cagan é generalizado aqui em outra dimensão, considerando mecanismos alternativos de formação de expectativas, que podem ser adaptativas, como no modelo original, ou racionais. A hipótese de que expectativas adaptativas sejam racionais é também considerada. Conclui-se que a imposição da condição de racionalidade ao modelo com expectativas adaptativas não produz alterações importantes nos valores estimados.
