Benchmark and Competitive Analysis of Port Performances Model: Algeciras Bay, Rotterdam, New York-New Jersey and Tangier Med (Published)
In this research paper four sea ports namely, Tanger Med, Algeciras Bay, Rotterdam and New York-New Jersey has been taken into study to understand and evaluate their efficiency of operations and benchmark them. Port efficiency is the measure of amount of input and output and their ratio. Port efficiency is not solely dependent on port performance. The port performance strategies of the case ports were studied and efficiency variables were found through various literatures. To analyze input and output variables of the ports, efficiency software named Data Envelopment Analysis Program was used to find the most efficient ports. Then the variables for the most efficient ports were benchmarked and ranked. A hypothetical port efficiency model has also been suggested for better efficiency of the ports.
The Determinants of Foreign Reserves in Nigeria (Review Completed - Accepted)
It has been seen that Foreign exchange reserves adequacy is a key component of good macroeconomic management. The modified version of the buffer stock model was applied to assess the determinants of foreign reserve in Nigeria. The study regressed foreign reserve variable on macroeconomic variables: real income, interest rate differential (a measure of opportunity cost), exchange rate volatility, financial openness, current account vulnerability, benchmark stock of reserves, and the demand for foreign exchange. In order to avoid any spurious regression results, the time series data from 1970 -2010 was subjected to stationarity tests. The ADF cointegration procedure used suggested the existence of long run relationships. Hence, the short run dynamics was examined by means of an error correction model. The empirical evidence shows that growth in Nigeria’s foreign reserves is not influenced in the long run by current account vulnerability (proxied by trade opennes), the opportunity cost of holding reserves (DID) and the benchmark stock of reserves but by other determinants such as the real Gross Domestic Products (Y), exchange rate volatility (Ev), financial openness (Fop), and the demand for foreign exchange (DFex).
