Aims:  To study the effect of changes in income as well as prices of beer and arrack, on alcohol sales in Sri Lanka during the period 1981–2017. Design:  The analyses were conducted by means of ARIMA time series analysis for arrack and beer separately. Measures: Yearly data on the sales of beer and arrack in the entire country were used. National GDP figures were used as a proxy measure of income, and yearly price data for arrack and beer were from Colombo, the largest metropolitan area in the country. Results:  No short-term effects of changes in price or income were found on sales. However, changes in the price of beer were significant, with a lag structure, which implies a delayed effect of price changes on the sales of beer. A significant cross-price effect of changes in the price of beer on arrack sales was found as well. Conclusions:  Sales of alcohol in Sri Lanka are not affected by price changes to the same extent as in high income countries. Most likely, the explanations will be found in the different drinking cultures between Sri Lanka and these countries.

This paper examines the determinants of food import demand in Africa taking the case of Nigeria using the ARDL bounds testing approach. Specifically, the study aims to estimates the short run and long run price and income elasticities of food import demand in Nigeria. The paper used annual time series data over the period 1981 to 2019. The empirical result indicates the existence of a long run equilibrium relationship between food import demand and its determinants. The long run price and income elasticities are -4.57% and 5.57%, respectively. The result shows that population and food production exert significant influence in determining food import demand in both the short run and long run while exchange rate is insignificant in the long run. The paper recommends that price and income-oriented policies will be effective measures in controlling food import demand in Nigeria.

Income And Price Elasticities

<p>Foreign trade policies applied to achieve economic growth and structural changes in the economies have an important role. The applications of these policies to determination of the direction, composition, and volume of exports and imports have affected on the price and income elasticities of exported and imported goods. Therefore, the export and the import policies must be analyzed with regards to the price and income elasticities. Considering the studies done so far, econometric analysis of supply and demand functions of export and import are generally seen analyzed based on a single equation model. Also simultaneous relationship between the supply and demand is mostly ignored. For this reason, the major aim of this study is to examine the simultaneous relationship between the supply and demand functions of export and import of manufacturing industry by using Two Stage Least Squares Method. According to results of estimation income and price elasticities for supply and demand of import are found compatible with the theory. Both in export and import demand equation of manufacturing, income and price elasticities are found positive and negative respectively. And also export and import supply elasticities for manufacturing are compatible with the theoretical expectations.</p><p> </p><p><strong>Özet</strong></p><p><strong></strong>Ekonominin büyümesi ve yapısal değişiminde, dış ticaret politikalarının önemli bir yeri vardır. İhracat ve ithalatın yönü, hacmi ve kompozisyonunu belirlemek amacıyla alınan kararlar, malların fiyat ve gelir esnekliklerine etkide bulunmaktadır. Bu nedenle bir ülkenin ihracat ve ithalat rejimi incelenirken, fiyat ve gelir esneklikleri de dikkate alınmalıdır. Bugüne kadar yapılan çalışmalar gözden geçirildiğinde, genellikle ihracat ve ithalat arz ve talep fonksiyonlarının ekonometrik analizinin tek denklemli model temel alınarak incelendiği görülmektedir. İhracat arz ve talep fonksiyonları arasındaki eşanlı gelir ve fiyat ilişkisi çoğunlukla göz ardı edilmektedir. Bu nedenle bu çalışmanın temel amacı; ihracat arz ve ithalat talep fonksiyonları arasındaki eşanlılık ilişkisini imalat sanayi özelinde, eşanlı denklem sistemlerinden iki aşamalı en küçük kareler yöntemi kullanarak incelemektir. Tahmin sonuçlarına göre, imalat sanayi ithalat arz ve talebine ait gelir ve fiyat esneklikleri ile imalat sanayi ihracat talebine ait gelir ve fiyat esnekliği ve ihracat arz denklemine ait gelir ve fiyat esnekliklerinin işareti teoriyle uyumlu bulunmuştur. </p>

This paper applies the collective household model to allocate household resources among household members. With a Collective Quadratic Almost Ideal Demand System (CQUAIDS) estimated by a Feasible Generalized Nonlinear Least Squares (FGNLS) method, it studies the household demand for six categories of household goods using household income and expenditure survey data from The Gambia, directed to studying the allocation of resources among young and adult members of households in The Gambia. It establishes the sharing rule for children and adult members of the household and shows the effect of demographic, distributive factor, price and income elasticities on the shares of household resources. The results establish that a higher share of resources goes for children while the sharing rule varies for different household types. Also, the findings show significant effects of demographic, distributive factor, price and income on the allocation of the household resources of consumption goods by the household.
