during a recession or a credit crunch, which could aggravate the downturn. A similar criticism has been directed at fair value accounting rules. The effect of the single Eurozone interest rate on the relatively high-inflation countries in the Eurozone periphery is also pro-cyclical, leading to very low or even negative real interest rates during an upturn which magnifies the boom (e.g. 'Celtic Tiger' upturn in Ireland) and property and asset price bubbles whose subsequent bust magnifies the downturns. Countercyclical Conversely, an economic or financial policy is called countercyclical if it works against the cyclical tendencies in the economy. That is, countercyclical policies are ones that cool down the economy when it is in an upswing, and stimulate the economy when it is in a downturn. Keynesian economics advocates the use of automatic and discretionary countercyclical policies to lessen the impact of the business cycle. One example of an automatically countercyclical fiscal policy is progressive taxation. By taxing a larger proportion of income when the economy expands, a progressive tax tends to decrease demand when the economy is booming, thus reining in the boom. Other schools of economic thought, such as new classical macroeconomics, hold that countercyclical policies may be counterproductive or destabilizing, and therefore favor a laissez-faire fiscal policy as a better method for maintaining an overall robust economy. When the government adopts a countercyclical fiscal policy in response to a threat of recession the government might increase infrastructure spending.
