Introduction The negative effects of inflation on economic activity are widely recognized. Inflation exerts a constraining effect on the key drivers of growth. The price increase reduces consumption and therefore production and employment. It exerts an inhibitory effect on investment, due to the rise of the nominal wages and the prices of raw materials, both in local and foreign currency. Inflation also contributes to the deterioration of trade balance when the prices of domestic goods and services rise more than those of foreign competitors. To this are added its negative effects on social activity because of the deterioration of the purchasing power. On the academic side, the economic literature has not stopped searching the causes of this phenomenon and finding its cures. It was first discussed the role of monetary and fiscal policies, and then discuss other factors such as the degree of central bank independence. However, over the last decade, a new wave theory has enriched this debate by focusing on the role of socio-political factors such as the degree of democratization of countries, considering these factors as the “deep determinants” of inflation and other macroeconomic pathologies. The thesis proposed by this new theoretical wave can be summarized by the following proposal of Satyanah and Subramanian (2007): If monetary or fiscal policy causes prices, what in turn causes monetary or fiscal policy and hence instability? Similarly, if the lack of central bank independence causes instability, why do some countries chose to have such 30 | The African Financial Review independence and others not? Such questions justify a search for deeper causes for instability. The present study falls within the framework of this academic renewal, which gives to socio- political and institutional factors, and more specifically, the degree of democratization, a leading role in explaining the causes of inflation and considers political participation a determinant tool for reducing it. Without calling into question the importance of the ‘classic’ instruments of control of inflation, that is monetary and fiscal policies, as well as other factors such as the degree of central bank independence, we are attempting to make a contribution to institutionalist theories, supporting the idea that these economic factors are “proximate determinants”, that are themselves subject to the effect of socio-political factors, which are the “deep determinants”. But it should be noted that the theoretical position that supports the existence of negative relationship between democracy and inflation has not made unanimity in the academic literature and some authors support the thesis that democracy can be a source of inflation. The “median voter” thesis of Hotteling (1929) and Downs (1957) is a very representative theoretical conceptualisation of this view. In other words, this thesis is commonly used as a theoretical underpinning of studies that supports a positive link between political participation and the rise in inflation. The second section of this paper provides a critical analysis of this thesis, by relating the Tunisian case study. Such an analysis allows presenting all aspects which turn around this debate and
