national currency depreciation or appreciation has always been argued seriously among policymakers since changing in exchange rate could cause improvement or deficit in trade balance. these changes affect the trade volume of a country in both short-run and long-run. long-run effects are recognized as the marshall-lerner condition, while short-run effects are analyzed by two concepts: j-curve an...

This paper evaluates the impact of the positive terms of trade (TOT) Shock on macroeconomic variables, using panel data for the six OPEC major oil exporting countries during 1989-2005. The findings indicate that the positive TOT shocks have the small and negative impact on savings and on the trade balance. Nevertheless, it has a positive impact on investment (specifically private investment) an...

â â â  given companies’ dynamic responses to expected exchange rate changes, this article improves on current methods of measuring exposure to foreign exchange rate changes by breaking down the spot exchange rate changes into expected changes and unexpected changes. the currency risk exposure coefficients resulting from an empirical analysis of shanghai stock exchange a share listed companies...

Special and differential treatment (S&D) for developing countries continues to be a defining feature of the multilateral trading system. This paper seeks to address key aspects of what has become an increasingly entangled and multi-faceted discussion. The paper begins by reviewing the historical context in which the relationship of developing countries with the multilateral trading system evolv...

We consider whether oil prices can account for business cycle asymmetries. We test for asymmetries based on the Markov switching autoregressive model popularized by Hamilton (1989), using the tests devised by Clements and Krolzig (2000). We select the transformation of the oil price of Lee, Ni and Ratti (1995), based on a linear analysis of the relationship between output growth and the oil pri...

A time series is estimated of in-ground prices of U.S. oil and natural gas reserve prices for the period 1982–2003, usingmarket transaction data. Reserves sold are considered as proved; errors in this respectmay affect estimates, in either direction. The data are also used to examine the impact of reserve status, production rate, andwell head prices, on reserve prices. Both oil and gas current ...

Acute volatile movements in primary commodity prices have drawn enough interests from empirical researchers. Exports of these commodities account for the bulk of export earnings of developing countries. The traditional demand based framework has been unable to explain the marked deterioration in these prices during 1980s. This paper tries to ascertain the role played by real oil prices in expla...

The literature on trade facilitation has mostly focused on implications for trade volumes. However, recent theoretical contributions have emphasized that trade costs – such as transaction costs related to cross-border trade procedures – affect both the traded volumes of “old” goods (the intensive margin) and the range of traded goods (the extensive margin). This paper therefore tests whether tr...

This paper investigates the determinants of the real exchange rate (RER) in Ethiopia. In particular, it assesses whether large capital inflows (e.g. foreign aid and remittances) have an impact on the RER. This empirical exercise tries to improve the current literature in a number of ways: (i) the use of quarterly data provides a larger sample size and enables the modelling of important intra-ye...

This paper suggests a new methodology for evaluating technological change in a multi-sector general equilibrium framework. The double calibration technique was applied to an ex post decomposition analysis of technological change between two periods, enabling a distinction to be made between price-induced and factor-biased technological changes for each sector. The method is applied to an empiri...
