Examine the salient features of the Phillips`s Curves. How might elementary textbooks be criticised for writing ‘inflation’ on the vertical axis? Introduction Philips curve‚ named after A.W. Philips‚ has caused many fierce debates in the area of macroeconomics since the World War II. Based on the data of wages and employment in UK from 1861to 1957‚ Phillips concluded that there had been an inverse relationship between the percentage rate of unemployment and the percentage rate of change in

PRODUCT CURVE: A curve that graphically represents the relation between total production by a firm in the short run and the quantity of a variable input added to a fixed input. When constructing this curve‚ it is assumed that total product changes from changes in the quantity of a variable input (like labor)‚ while other inputs (like capital) are fixed. This is one of three key product curves used in the analysis of short-run production. The other two are marginal product curve and average product

Considering the production of maize and shirts in Botswana‚ we can use the notion of the production possibilities curves to determine levels of efficiency‚ inefficiency‚ economic growth and technological improvement. The production possibilities curve (PPC) is a graph that shows the different quantities of the two goods (in this case‚ maize and shirts) that an economy (Botswana) could efficiently produce with the limited productive resources. To be able to illustrate this simply we assume that

Learning curve effect explains relationship between experience and productivity. According to learning curve effect‚ if time consulting‚ completed transactions do again‚ spending time that is required for transaction will shrink and productivity of work will increase. Learning curve effect is observable in every area of life. For example‚ we deal with a software developer. Learning first programming language at high level takes about two years for the software developer. The same software developers

The Phillips Curve and the Philippines According to Cristeta B. Bagsic‚ the Phillips Curve “depicts the trade-off between inflation and unemployment rate” (“The Phillips Curve and Inflation Forecasting: The Case of the Philippines”). Nowadays‚ the relationship depicted by the Phillips curve is specified in the following equation: πt = πe – γ(UR – UR*) + v where πt is the inflation rate‚ πe is the expected inflation‚ γ is a parameter‚ UR is the unemployment rate‚ UR* is the natural rate of unemployment
