AbstractThe 16 April 2016 earthquake in Ecuador exposed the significant weaknesses concerning the methodological designs to compute—from an economic standpoint—the consequences of a natural hazard-related disaster for productive exchanges and the accumulation of capital in Ecuador. This study addressed one of these challenges with an innovative ex ante model to measure the partial and net short-term effects of a natural hazard-related catastrophe from an interregional perspective, with the 16 April 2016 earthquake serving as a case study. In general, the specified and estimated model follows the approach of the extended Miyazawa model, which endogenizes consumption demand in a standard input–output model with the subnational interrelations and resulting multipliers. Due to the country’s limitations in its regional account records the input–output matrices for each province of Ecuador had to be estimated, which then allowed transactions carried out between any two sectors within or outside a given province to be identified by means of the RAS method. The estimations provide evidence that the net short-term impact on the national accounts was not significant, and under some of the simulated scenarios, based on the official information with respect to earthquake management, the impact may even have had a positive effect on the growth of the national product during 2016.

This paper presents a case-study to demonstrate the calculation methods of growth contributions using structural decompositions of input-output tables and their Hungarian applications. Although the required data are available with a considerable time-lag, results show that taking backward linkages through demand for inputs and value chain multipliers into account can significantly alter the picture on the growth effects of industries and final demand categories by the conventional approach based on quarterly GDP calculations. This can be instructive for analysts and policy- and decision-makers not only in Hungary, but also in other countries. The study was performed by using public macroeconomic and sectoral data obtained from the Hungarian Central Statistical Office.

The Changing Functions of a Rural Port: Dumfries, 1700-1850

This essay is a case study of the development of the Port of Dumfries, and the surrounding mercantile activity during the eighteenth and first half of the nineteenth century. Author Carol Hill argues that despite its small size, the Port of Dumfries was significant to both local and national economies. Using Dumfries, the essay also explores the changing function of ports due to the industrialisation of the shipping industry. The conclusion considers Dumfries a successful port, due to a willingness to adapt to change, especially in light of its limited facilities.

The chapter is organized as follows: In section 1, the basic definitions of the security risk analysis and the characteristics of the railway security problem are introduced, and a bibliography review is reported. Then, in section 2, the general architecture for designing a security risk analysis tool is presented, focusing on the relevant specifications, and on the input/output characteristics. Therefore, in section 3, with the aim of pointing out the characteristics of the presented architecture, an explicative case study is defined based on real world data coming from Italian railways. Finally, some conclusions and remarks are discussed in chapter 4.
