pigou effect and liquidity trap

An economy that is in the form of a liquid trap cannot make use of the monetary stimulus to increase output.

The standard classical counterargument, which relies upon the Pigou effect, has typically been conducted in a comparative-static framework. Mayer even adds support to our argument: "In a three-asset model the demand for money is absolute only if agents refuse to hold additional quantities of both the other two assets" (p. 654). We argue in this paper that the nature and significance of Pigou's (1943, 1947) comments on Keynes have been frequently misinterpreted. How is the Pigou effect supposed to get you out of a liquidity trap? Although Keynes made great points on this issue, the classical economists have something to say. The standard classical counterargument, which relies upon the Pigou effect, has typically been conducted in a comparative-static framework. The present paper develops a dynamic analysis, in a rather standard model, under the assumption that expectations are formed rationally. The liquidity trap is a situation defined in Keynesian economics, the brainchild of British economist John Maynard Keynes (1883-1946).Keynes ideas and economic theories would eventually influence the practice of modern macroeconomics and the economic policies of governments, including the United States. Notably absent from these new models of the liquidity trap, however, is another old idea: that of the real balance effect. The standard classical counterargument, which relies upon the Pigou effect, has typically been conducted in a comparative-static framework. Pigou fully recognised that interest-rate effect of Keynes that wage-price deflation raises investment and income through a reduction in the interest rate. Share. Many of his works were used by other influential economists as their basis to put forward contrasting views to Keynesian economics. The Pigou Effect, on the contrary, accounts for a fall in the aggregate demand via rising real balances, which raises expenditure via the income effect. But, as James Tobin has recently emphasized, the more relevant issue concerns the dynamic response (in "real time") of an economy that has been shocked away from full employment. The liquidity trap is an enigma which manifests itself under widely different circumstances. The Liquidity Trap and the Pigou Effect: A Dynamic Analysis with Rational Expectations By BENNETT T. MCCALLUM Carnegie-Mellon University and National Bureau of Economic Research INTRODUCTION For several decades, students of macroeconomic theory have learned about the "Keynes v. the Classics" debate of the late 1930s and early 1940s. The effect that bears his name evolved in response to Keynes, and in particular the idea of a liquidity trap. Keynes Effect: A Keynesian economics concept that essentially disappears in the wake of a liquidity trap; Pigou Effect: A concept that describes a scenario in which monetary policy could be effective even within the context of a liquidity trap; Liquidity: The primary behavioral driver behind the liquidity trap Overview of what is financial modeling, how & why to build a model., the art of building an abstract representation of a company and it’s future performance. There are several shortcomings with this argument. Unlike in Keynes (1936), this is a Supply Side Liquidity Trap, SSLT, which challenges the Pigou effect, e.g., it may not be eliminated by a massive helicopter-type increase in liquid government liabilities or large fall in prices and wages. If the decline in prices is gradual, people do not know where or when it will stop, and both producers and consumers will hold onto their money, which leads to a liquidity trap. In particular, we suggest that Pigou's logic implies not only that monetary policy will be successful in escaping unemployment in the liquidity trap situation, but also that it is a Pareto optimal means of doing so. First discussed by de Scitovszky (1941), Haberler (1946), and Pigou (1943) and developed most extensively by Patinkin (1965), the real balance effect … I was taught to dismiss the Pigou effect. As unemployment goes up, the price level drops hence increasing real balance causing the consumption t… Consumer surplus is an economic measurement to calculate the benefit (i.e., surplus) of what consumers are willing to pay for a good or service versus its market price. However pretty well everyone agrees that if by some means the monetary authority could induce higher inflation expectations, then the ZLB could be overcome, because real interest rates would fall, stimulating demand.

Pigou’s conclusion was that the economy would operate on an equilibrium less than the full employment equilibrium only if prices and wages were constant. The what effect? What caught me in the Waldmann piece, however, was the brief discussion of the Pigou effect, which supposedly refuted the notion of a liquidity trap. 163-165.

Pigou's hypothesis and the liquidity trap An economy in a liquidity trap cannot use monetary stimulus to increase output because there is little connection between personal income and money demand. Pigou effect and liquidity trap are incompatible. and shows that it could give rise to liquidity trap conditions under perfectly flexible prices. Indeed, this is the case in the liquidity trap. 166-167. Although Keynes made great points on this issue, the classical economists have something to say.

Pigou argued that even though the liquidity trap might bar the way to an increase in employment—via changes in interest rates and investment—falling wages and prices would sooner or later restore full employment because a decline in the price level would cause the consumption function to shift up.

Pigou argued that even though the liquidity trap might bar the way to an increase in employment—via changes in interest rates and investment—falling wages and prices would sooner or later restore full employment because a decline in the price level would cause the consumption function to shift up. A Keynesian idea of considerable historical importance is that, in the presence of a liquidity trap, a competitive economy may lack--despite price flexibility--automatic market mechanisms that tend to eliminate excess supplies of labor. According to John Hicks thinking, this could be another reason for the persistently high rate of unemployment. 395-405. citation courtesy of. Thus, Pigou (1943) proposed, even the "special cases" of a liquidity trap or interest-insensitive investment are not sufficient to maintain unemployment equilibrium as the rightward shifts of the IS curve via the "Pigou Effect" will ensure we are taken to full employment equilibrium.
