This paper assesses the day of the week effect of the daily depreciation of the Turkish lira (TL) against the US dollar (USD) and its volatility. The empirical evidence from Turkey presented here suggests that Thursdays are associated with higher and Mondays with lower depreciation rates compared to those of Wednesdays. Moreover, Mondays and Tuesdays are associated with higher volatility than Wednesdays.
a b s t r a c t a r t i c l e i n f oThis paper provides a set of empirical evidence from five Northern Mediterranean countries that are subject to similar refinery reference prices regarding the relative sensitivity of crude oil prices and exchange rate on (pre-tax) petroleum product prices. The empirical evidence reveals that a one percent increase in exchange rate (depreciation) increases petroleum product prices less than a one percent increase in crude oil prices does in the long run. In the short run, however, a one percent increase in exchange rate increases petroleum product prices more than a one percent increase in crude oil prices does.
This paper investigates the nature of the output-employment relationship by using the Turkish quarterly data for the period 1988-2008. Even if we fail to find a long-run relationship between aggregate output and total employment, there are long-run relationships for the aggregate output with non-agricultural employment and sectoral employment levels for seven of nine sectors that we consider. However, a further investigation for the output and employment relationship within a shortrun perspective does not reveal statistically significant relationships for either total employment or non-agriculture employment, or eight of the nine sectors that we consider. Although there are various long-run relationships between output and employment, the short-run links between demand and employment are weak. The various implications of this for the economy and the labour market are discussed. As a result, maintaining high levels of output in the long-run creating demand is essential for employment generation.
This paper assesses the presence of seasonal volatility in price indexes where a similar type of pattern has been reported in asset prices in financial markets. The empirical evidence from Turkey for the monthly period from 1987:01 to 2007:05 suggests the presence of seasonality in the conditional variance of inflation. Thus, inferences for the models that do not account for the seasonality in the conditional variance will be misleading.JEL classification codes: E31; E37, E30.
