The Minimum Food Security Quota (MFS-Quota) in Food Security Policy Modelling

This paper proposes the construction of the Minimum Food Security Quota (MFSQuota)using mathematical economic modelling in real time. The MFS-Quota fixes a certain amount of annual food storage to prepare a country for any natural or social disasters. Any country can construct its own MFS-Quota for “food security policy”.- econographicology, food security, economic development

The Laspeyres bias in the Spanish consumer price index

The CPI compares the cost of acquiring a reference quantity vector at current and base prices. Such reference vector is the vector of mean quantities actually bought by a reference population, whose consumption patterns are investigated during a period t prior to the index base period 0. In this paper we show that unless one takes into account the price change between these two dates, the CPI ceases to be a proper statistical price index of the Laspeyres type. Among several negative consequences, the most important is that this omission produces a bias in the measurement of inflation which we call the `Laspeyres bias.' Using Spanish data, we estimate that, e.g., from 1992 to 1998, the size of the Laspeyres bias is -0.061 per cent per year, or about 6 per cent (in absolute terms) of the positive bias estimated by the Boskin commission for the U.S., which is equal to 1.1 per cent per year. The Laspeyres bias in shorter time periods reached -0.122, and -0.108 per cent per year in 1992, and 1997, respectivel

The plutocratic bias in the CPI : evidence from Spain

We define the plutocratic bias as the difference between the inflation measured according to the current official CPI and a democratic index in which all households receive the same weight. (i) We estimate that during the 1990s the plutocratic bias in Spain amounts to 0.055 per cent per year, or about one third of the classical substitution bias estimated by the Boskin Commission for the U.S. (ii) We find that a 16-dimensional commodity space can be conveniently reduced to 3 dimensions, consisting of a luxury good and two necessities. The price behavior of these 3 goods provides a convincing explanation of the oscillations experimented by the plutocratic bias. (iii) Finally, the fact that the plutocratic bias is positive during this period, implies that the change in money income inequality is between 2 and 5 per cent greater than the change in real income inequality. We study the robustness of these results to the time period considered and to the definition of the group index which serves as an alternative to the CPI. We estimate that during the 1980s and the second part of the 1970s in Spain, the plutocratic bias is 0.033 and 0.239 per cent per year, respectively

The plutocratic gap in the CPI : evidence from Spain

The plutocratic gap is defined as the difference between the inflation measured according to the current official consumer price index (CPI) and a democratic index in which all households receive the same weight. During 1992–97, the plutocratic gap in Spain averaged 0.055 percentage points a year. Since positive and negative gaps cancel out, however, the average absolute gap is significantly larger: 0.090 percentage points a year. For the purposes of accounting for the plutocratic gap, a 53-dimensional commodity space can be conveniently reduced to two dimensions: a luxury index and a necessities index.Publicad

A New Multi-Dimensional Framework for Analyzing Regional Integration: Regional Integration Evaluation (RIE) Methodology

Theories of regional integration typically analyze the regional integration process from the perspective of a single discipline, usually economics. However, such one-dimensional analytical frameworks cannot fully capture the richness and complexity of the inherently multi-dimensional regional integration process. To address the problem, we propose the regional integration evaluation (RIE) methodology which is based on four dimensions of development – economic, political, social and technological. The central idea behind the RIE methodology is that regional development promotes regional integration. Our RIE methodology differs from the existing literature in that it is based on a more comprehensive definition of development than just economic development. Our definition of a region's development incorporates the development levels of all regional countries as well as differences in development levels among regional countries. We apply the RIE methodology to assess the regional development and hence integration prospects of NAFTA, ASEAN, MERCOSUR and EU.Economic integration; economic modeling; NAFTA; ASEAN; MERCOSUR; EU

Distributive aspects of the quality change bias in the CPI.

This paper shows that the richer households are significantly more affected by the quality-change bias (QCB) in the CPI. The empirical analysis combines the detailed information pertaining to the size of the QCB for the US with household-specific CPIs for Spain.Plutocratic gap; Money inequality; Price index; CPI; Quality bias;

The Laspeyres bias in the Spanish consumer price index.

The CPI compares the cost of acquiring a reference quantity vector at current and base prices. Such reference vector is the vector of mean quantities actually bought by a reference population, whose consumption patterns are investigated during a period tau prior to the index base period 0. This paper shows that unless the price change between these two dates is taken into account, the CPI ceases to be a proper statistical price index of the Laspeyres type. Among several negative consequences, the most important is that this omission produces a bias in the measurement of inflation: the 'Laspeyres bias'. Using Spanish data, the size of the Laspeyres bias is estimated at -0.061% per year, during 1992-1998. The Laspeyres bias in shorter time periods reached -0.122% per year in 1992, and -0.108 in 1997.
