Money Circulation Equation Considering Time Irreversibility  [PDF]
Shinji Miura
Advances in Linear Algebra & Matrix Theory (ALAMT) , 2014, DOI: 10.4236/alamt.2014.44016
Abstract: The essence of money circulation is that money continues to transfer among economic agents eternally. Based on this recognition, this paper shows a money circulation equation that calculates the quantities of expenditure, revenue, and the end money from the quantity of the beginning money. The beginning money consists of the possession at term beginning, production and being transferred from the outside of the relevant society. The end money consists of the possession at term end, disappearance and transferring to the outside of the relevant society. This equation has a unique solution if and only if each part of the relevant society satisfies the space-time openness condition. Moreover, if money is transferred time irreversibly, each part of the relevant society satisfies the space-time openness condition. Hence, the solvability of the equation is guaranteed by time irreversibility. These solvability conditions are similar to those of the economic input-output equation, but the details are different. An equation resembling our money circulation equation was already shown by Mária Augustinovics, a Hungarian economist. This paper examines the commonalities and differences between our equation and hers. This paper provides the basis for some intended papers by the author.

Tourism and Economic Development in Romania: Input-Output Analysis Perspective
MARIUS SURUGIU,CAMELIA SURUGIU
Revista Romana de Economie , 2010,
Abstract: Tourism provides a lot of opportunities for sustainable economic development. At local level, by its triggering effect it could represent a factor of economic recovery, by putting to good use the local material and human potential. By its position of predominantly final-branch, tourism exercises to a large impact on national economy by the vector of final demand, for which the possible and/or desirable variant for the future is an economic-social demand that must be satisfied by variants of total output. Using the input-output model (IO model) a comparison was made of the matrix of direct technical coefficients (aij) and the one of the total requirement coefficients (bij) with the assistance of which the direct and propagated effects were determined for this activity by the indicators defining the dimensions of national economy.

Journal of Agronomy , 2006,
Abstract: Energy and economic analysis in rose production in Isparta province where there is intensive-rose production were performed. A total of 11 villages from Isparta Centre, Atabey, Keciborlu, G nen, districts of Isparta province were surveyed by applying a face to face questionnaire method with 109 rose growers. Results revealed that total energy consumed per hectare for rose production was 29313.12 MJ ha-1 and the most energy demanding input was chemical fertilizers (46.67%), especially nitrogen (39.81%). Energy consumption due to diesel fuel was 21.87% of the total energy input. Total bioenergy output was calculated as 21150.69 MJ ha-1 considering its yield (5041.88 kg ha-1) and its energy contents (4.20 MJ kg-1) Energy use efficiency, specific energy and energy productively of rose production were found to be 0.72, 5.81 MJ kg-1 and 0.17 kg MJ-1, respectively. It was concluded that the direct and indirect energy inputs were 36.08 and 58.90% of the total energy input, respectively. Renewable energy sources among the inputs constituted 16.43% of the total energy whereas non-renewable resources among the inputs constituted 16.43% of the energy whereas non-renewable resources (chemical fertilizers and diesel fuel) constituted 78.55% of total energy input. Result showed that net return from rose production in the surveyed farms was at satisfying level. Benefit to cost ratio was found to be 1.58.
Analyzing Some Economic Relations Based on Expansion Input-output Model  [cached]

International Journal of Business and Management , 2012, DOI: 10.5539/ijbm.v7n19p96
Abstract: This paper is trial attempt for introducing the concept of Leontief inverse matrix and the Leontief extended system for Keynes multipliers, which can analyze the relationship between income groups and consumer groups, respectively. The model is also used to analyze the structure of income in order to describe quantitatively the relationship between income from production and income not from production. The empirical study used the Vietnam input-output table, 2005.
Economic and Policy Implications of Industry Interdependence: An Input-output Approach  [cached]
Daniel Gravino
International Journal of Economics and Finance , 2012, DOI: 10.5539/ijef.v4n6p22
Abstract: The study provides an overview of the fundamental principles of input-output theory, the steps involved in linkage analysis and the estimation of industry multipliers. These have been estimated using a ‘new’ symmetric input-output table for the Maltese economy for 2007 which is used as an example to draw policy-relevant lessons for countries with relatively small open economies. On the basis of these estimates it is argued that (1) the effect of an increase in final demand will go beyond the industry directly affected by the initial change in expenditure, (2) that multipliers provide an important guide to policy makers that are concerned with making optimal use of their scarce resources, (3) that governments of countries that depend heavily on foreign direct investment can target labour intensive industries to tilt the balance in favour of the worker, (4) that a firm-specific approach is preferable to expansionary fiscal policy when a country is heavily dependent on imported products, and (5) that market distortions and inefficiencies are more damaging in those sectors that have strong forward linkages with other sectors in the domestic economy. New RpO"m@:?erning:0pt;mso-fareast-language:EN-US'> The findings of the paper are useful for financial decision making.
Input-Output Energy and Economic Analysis of Strawberry Production in Iran  [PDF]
Rasol Loghmanpor
American Journal of Engineering Research , 2013,
Abstract: The aim of this study was to determine the energy consumption and economic analysis for strawberry production. The data were collected from 80 farmers growing strawberry in the Babolsar zone of Iran by using a face-to-face questionnaire in May-June 2012. The plowing operation at the study area was done by two methods; manually plow and machinery plow. In addition, the irrigation operation was done by two methods; pumping irrigation and non-pumping irrigation. Total energy used in various farm operations during strawberry production was 22275.8 MJ.ha-1. Total energy output was 14820 MJ.ha-1, and the average annual yield of strawberry farms was 7800 kg. ha-1. The energy ratio, productivities, specific and net energy gain were 0.58, 0.3 kg.MJ-1, 3.33 MJ.kg-1and -9355.8 MJ.ha-1, respectively. The profit/cost ratio, productivity, and net profit in the strawberry production are 1.37, 1.1 kg.$-1and 2333.4 $.ha-1, respectively. In addition, the net return in the non-pumping and manually plow method is significantly higher than in the other methods
Propagation of Economic Shocks in Input-Output Networks: A Cross-Country Analysis  [PDF]
Martha G. Alatriste Contreras,Giorgio Fagiolo
Quantitative Finance , 2014,
Abstract: This paper investigates how economic shocks propagate and amplify through the input-output network connecting industrial sectors in developed economies. We study alternative models of diffusion on networks and we calibrate them using input-output data on real-world inter-sectoral dependencies for several European countries before the Great Depression. We show that the impact of economic shocks strongly depends on the nature of the shock and country size. Shocks that impact on final demand without changing production and the technological relationships between sectors have on average a large but very homogeneous impact on the economy. Conversely, when shocks change also the magnitudes of input-output across-sector interdependencies (and possibly sector production), the economy is subject to predominantly large but more heterogeneous avalanche sizes. In this case, we also find that: (i) the more a sector is globally central in the country network, the largest its impact; (ii) the largest European countries, such as those constituting the core of the European Union's economy, typically experience the largest avalanches, signaling their intrinsic higher vulnerability to economic shocks.
