# BusinessCycleRegularities

In this exercise, you are asked to analyze the extend to which the numbered business cycle facts

discussed in this chapter apply to (a) country A and (b) country B. To this end compute

the relevant business cycle statistics for the following four alternative detrending methods: 

(a) log-linear detrending; 

(b) log-quadratic detrending; 

(c) Hodrick Prescott filtering with λ = 100;

(d)Hodrick Prescott filtering with λ = 6.25. 

Make a two by two graph showing the natural logarithm of real per capita GDP and the trend, one panel per trend. 

Discuss how the detrending methodinfluences the volatility of the cyclical component of output. Also discuss which 

detrending method identifies recessions for the country B most in line with the NBER business cycle dates. The data should

be downloaded from the World Bank’s WDI database. As the sample period for country A use

1960 to 2011 and for the country B use 1965-2011. Specifically, use the following time series to

construct the required business cycle statistics:

\*GDP per capita (constant LCU) NY.GDP.PCAP.KN

\*Household final consumption expenditure, etc. (% of GDP) NE.CON.PETC.ZS

\*Gross capital formation (% of GDP) NE.GDI.TOTL.ZS

\*General government final consumption expenditure (% of GDP) NE.CON.GOVT.ZS

\*Imports of goods and services (% of GDP) NE.IMP.GNFS.ZS

\*Exports of goods and services (% of GDP) NE.EXP.GNFS.ZS
