    A comparative analysis of dollarization in Tanzania and Argentina
    (2014-01-14) Agwambo, Neema John
    This study examined the portfolio theory of dollarization of Ize and Yeyati (2003) to see if it holds in Argentina and Tanzania, this study was conducted to see if the variables of the exchange rate volatility and inflation rate fluctuation contribute to dollarization. Moreover, it shows that there is a relationship between the level of dollarization on nominal interest rate, inflation rate and exchange rate as the portfolio theory predict. The Chow test (Chow (1960) was used to test for the equality of coefficients in Argentina and Tanzania as separate samples. The results indicated that the correlation analysis and regression analysis in both countries there is disagreement over the assumptions and showed that exchange rate, inflation rate and interest rates do not have a significant effect on the level of dollarization. This means that the theory of portfolio do not hold for the case of Tanzania and Argentina and it is suggested that because the nature of the relationship is not linear, a new research design can be developed or it simply means that the portfolio theory is incorrect. We recommend that further research be pursued using the same variables as in this study but using different forms, such as using real as opposed to using nominal values, using non-linear forms instead of using a linear estimation method. Or the search for the significant explanatory variable of dollarization and the variables could only be included in a process that calls for the formulation of new theory to replace the current theory. The new variables to be included are government quality, monetary policy agility, individual heterogeneity, domestic debt, default risk, institutional quality and financial integration.
