“…The literature suggests that democracy favors the rising of public spending due to increased redistribution demands (Aidt et al, 2006), trade union pressure for wage increases (Rodrik, 1999) and the opportunistic behavior of politicians during elections (Drazen and Eslava, 2010). A number of explanatory variables are introduced into the equation: economic growth which leads to an increase in demand for public services (Adsera and Boix, 2002), the population growth which is assumed to have a negative effect on public consumption due to economies of scale (Alesina and Wacziarg, 1998), natural rents that are often used to finance public expenditure (Ross, 2001), public debt that has a crowding out effect on public expenditure (Mahdavi, 2004), inflation that can lead to a reduction in public spending due to the deterioration in the real value of tax revenues (Zakaria and Shakoor, 2011), and trade openness which can lead to lower taxes and thus decreasing spending (Schulze and Ursprung, 1999).…”
