We compile a historical dataset covering nearly 40 years of booms and busts in the commodity terms of trade of over 150 countries. We discuss the characteristics of these events and their effects on macroeconomic performance and, in particular, compare the most recent commodity-price cycle with its historical precedents.
This paper assesses the presence of opportunistic electoral budget cycles in Papua New Guinea. Using quarterly time series data, a clear pattern emerges of pre-election manipulations of fiscal policy by incumbent governments, mainly in the form of increased development spending and overall primary expenditure, followed in some cases by retrenchment in post-election periods. These findings are consistent with the predictions of rational opportunistic political business cycle theory. It is noteworthy that revenue was not statistically significantly related to elections, either in the pre- or post-election period. In this regard, electoral swings in fiscal deficits reflect a preference for influencing expenditures rather than taxation.
