Construction of an economic index to measure the causes of economic insecurity

This paper is an updated study on the causes of economic insecurity in the United States. The authors have constructed an aggregate composite index that measures objectively the major causes of economic insecurity (CEI) in the United States. The CEI index consists of 11 variables that can cause economic insecurity. The time period under investigation is 1960 through 2001. A rising CEI index indicates that the causes of economic insecurity in the United States have increased in relative importance, which results in an increase in economic insecurity. Conversely, a falling CEI index indicates that the causes of economic insecurity have declined in relative importance, which results in a reduction of economic insecurity. However, despite substantial economic growth in the American economy from 1960 through 2001, the CEI index overall showed little improvement. The major conclusion is that the CEI index was 9 percent higher in 2001 than it was in 1960. This result was due largely to the increase in divorce, violent crime, rising out-of-pocket expenditures for health care, inflation, and unemployment. The results for subperiods are dramatically different, and we think more interesting, than the overall results. During the 1960s, there was a small decline in the CEI index. The 1970s showed a dramatic increase in the CEI index, which reflected both high unemployment rates and inflation rates during this period. The 1980s experienced fluctuating levels in the index but little overall change, and the 1990s experienced a sharp decline in the CEI index due largely to a robust economy. The CEI index has increased more recently, which reflects largely the recent 2001 business recession. The correlation coefficient of the CEI index with the University of Michigan's well-known Index of Consumer Sentiment is ?676. This figure shows that as the CEI index rises, consumer sentiment about the American economy becomes pessimistic and negative.

Well-being and/or quality of life in EU countries through a multidimensional index of sustainability

The aim of my paper is to demonstrate that Sen's theory of well-being can be applied to make the concept of sustainable human development operational through the building of a multidimensional index of sustainability which takes into account, at the same time, economic, social and environmental variables. This index may be considered an alternative to the current measures of welfare/sustainability since not only conventional measures such as GDP, but also multi-attribute indices, such as Human Development Index (HDI), Genuine Savings, Index of Sustainable Economic Welfare (ISEW) etc., are found to be inadequate to make the concept of sustainable development operational. Therefore, the limitations of these measures of welfare/sustainability justify the search for a new index of sustainability. This index will show, at the operational level, how Sen's theory of well-being can be useful to sustainable development. It was applied to EU countries using the standardised deviation methodology being the closest and most suitable methodology to be adopted for building multidimensional indices. The factor analysis methodology will also be used in my paper. Lastly, the comparison between Sen's trend of sustainability and GDP trend index number-which are both of them applied to Italy-will show how much the criticisms and the limitations directed towards the indicator of GDP are founded.     

The impacts of energy insecurity on household welfare in Cambodia: Empirical evidence and policy implications

This study investigates the impacts of energy insecurity on household welfare in Cambodia. The notion of energy insecurity is not well understood in the literature as well as in local contexts. This study defines household energy insecurity as the status quo derived from the interplay of inadequate and insufficient energy consumption that prevents households from meeting basic energy needs. The notion of energy insecurity can only be well understood by investigation in the local context as it varies from place to place. Households facing insufficient energy consumption may forgo many other opportunities. Once energy security has been defined in the Cambodian context, the study employs multiple regression models using the Cambodia Socio-Economic Survey Data (2015) to investigate the impacts of household energy insecurity. The study confirmed that energy insecurity has enormous negative impact on welfare of the households, with a further negative impact on the human capital formation of the children. The findings will lead to policy implications to improve household energy security, and thus impact economic, social, and environmental development.     

Job insecurity and mental health in Canada

Using six cycles of Canada’s longitudinal National Population Health Survey data (2000–2001 to 2010–2011), this article examines the relationship between job insecurity and mental health. Job insecurity is evaluated in both subjective (perception of job insecurity) and objective (probability of joblessness) terms while mental health is measured using a standardized psychological distress index. Applying a person-specific fixed-effects estimator, results indicate that for males and females age 25–64, job insecurity, regardless of how it is measured, is associated with an increase in psychological distress. Results regarding unemployment are not as conclusive, suggesting that it is not so much the actual occurrence of job loss but the threat of unemployment that is associated with higher psychological distress. Estimates of the relationship between job insecurity and psychological distress using pooled ordinary least squares are much larger, implying that much of the psychological distress/job insecurity correlation may be due to unobservable fixed characteristics. All results are robust to the inclusion and exclusion of a host of other potential determinants including income-related variables, education, and various health measures.     

A multivariate time series analysis of energy consumption,real output and pollutant emissions in a developing economy: New evidence from Nepal

Mountain economies will have to play a central role in attaining the global pursuit of green economic growth as crucial bearers of ecosystems goods and services. However, these economies are not adequately represented in the development policy debates in spite of their fundamental importance towards global sustainable development. This study examines the inter relationships between energy consumption, output and carbon emissions in a developing mountainous economy using an augmented Vector Autoregression model. Time-series data over the period 1975–2013 is studied applying a multivariate framework using population and gross fixed capital formation as additional variables for Nepal. Testing for Granger causality between integrated variables based on asymptotic theory reveals a long-run unidirectional Granger causality running from GDP to energy consumption, and a unidirectional Granger causality running from carbon emissions to GDP. We suggest that the government of Nepal can address energy poverty by accelerating the adoption energy conservation policies such as rationing energy consumption and energy efficiency improvements to narrow the energy supply-demand gap. The opportunity to promote the uptake of decentralised off-grid renewable technologies in remote areas and the large scale development of hydropower at the national level also needs to be prioritized. Our results remain robust across different estimators and contributes to an emerging literature on the nexus relationships between energy consumption, income and carbon emissions in mountainous developing economies.

International sanctions’ impact on energy efficiency in target states

This paper investigates the impact of international sanctions on energy efficiency by employing the panel fixed effect as well as average marginal effect from the Tobit model via data on 30 sanctioned states over the period 1996–2015 with international sanctions including unilateral, plurilateral, U.S., EU, UN, economic, and non-economic cases. Overall, we find that the imposition of unilateral sanctions leads to a 0.067% decrease in energy efficiency, but that of plurilateral sanctions positively contribute to energy efficiency in the case of the full sample of countries. Moreover, the imposition of UN sanctions has a greater decrease on energy efficiency in the target states than the 0.042% reduction of energy efficiency when the sanctionist is the U.S. For robustness, empirical results indicate that the imposition of plurilateral sanctions results in a drop of energy efficiency in Islamic countries, but an increase in non-Islamic countries, while there are also negative shocks induced by the imposition of EU sanctions on energy efficiency in Asian countries, but not for non-Asian countries. We also consider endogenous problems and dynamic specification by using indicator variables and System GMM. In summary, our empirical findings provide policy suggestions for those sanctioned countries about how to maintain energy efficiency when facing international sanctions.     

A model of technological breakthrough in the renewable energy sector

Models with induced technological change in the energy sector often predict a gradual expansion of renewable energies, and a substantial share of fossil fuels remaining in the energy mix through the end of our century. However, there are historical examples where new products or technologies expanded rapidly and achieved a high output in a relatively short period of time. This paper explores the possibility of a ‘technological breakthrough’ in the renewable energy sector, using a partial equilibrium model of energy generation with endogenous R&D. Our results indicate, that due to increasing returns-to-scale, a multiplicity of equilibria can arise. In the model, two stable states can coexist, one characterized by a lower and one by higher supply of renewable energy. The transition from the low-output to the high-output equilibrium is characterized by a discontinuous rise in R&D activity and capacity investments in the renewable energy sector. The transition can be triggered by a rise in world energy demand, by a drop in the supply of fossil fuels, or by policy intervention. Under market conditions, the transition occurs later than in the social optimum. Hence, we identify a market failure related to path-dependence and technological lock-in, that can justify a strong policy intervention initially. Paradoxically, well-intended energy-saving policies can actually lead to higher emissions, as they reduce the incentives to invest in renewable energies by having a cushioning effect on the energy price. Hence, these policies should be supplemented by other instruments that restore the incentives to invest in renewable energies. Finally, we discuss the influence of monopoly power in the market for innovations. We show that market power can alleviate the problem of technological lock-in, but creates a new market failure that reduces static efficiency.     

Does Ecological Footprint Impede Economic Growth? An Empirical Analysis Based on the Environmental Kuznets Curve Hypothesis

This paper examines the relationship between income and environmental quality using environmental Kuznets curve (EKC) hypothesis. The hypothesised link is tested using time‐series analysis of 22 countries over the period 1961–2011. The degree of environmental impacts of economic activity is measured using ecological footprint (EF) per capita as explanatory variable, while real gross domestic product (GDP) per capita and its quadratic and cubic forms are used as predictor variables in these countries. First, the EKC hypothesis is tested through examining the relationship between EF and GDP using linear, quadratic and cubic functions. Further, the long‐run relationship between EF and GDP is investigated using a vector error correction model. It was found that there is a cointegrated relationship between the variables in almost all countries, which was statistically significant, and EKC supported in 10 countries. Additionally, almost all error correction terms are correct in sign and are significant, which implies that some percentage of disequilibria in EF in the previous year adjusts back to the long‐run equilibrium in the current year. Therefore, an efficient trade‐off between environmental protection and economic benefits should be taken, and EF should be reduced through changing consumption patterns, improving the efficiency of use of resources and cleaner technology choices.

Changes in social welfare and sustainability: Theoretical issues and empirical evidence

We analyze the time derivative of a Ramsey-Koopmans social welfare function (R-K SWF), as an indicator of genuine investment and current change in social welfare (CSW) conditions, when feedback or arbitrary rules are used for selecting policy variables in non-optimizing economies. When policy variables are selected arbitrarily, their accounting prices should determine current CSW in addition to the accounting prices of the economy's assets and genuine investment should be adjusted accordingly. We use our theoretical framework to characterize CSW conditions for non-optimizing economies, based on direct estimation of accounting prices. We use our theoretical model to provide empirical evidence regarding the CSW conditions for the Greek economy.

Barriers to energy efficiency: A comparison across the German commercial and services sector

Based on a large sample for the German commercial and services sector, this paper econometrically assesses the relevance of various types of barriers to energy efficiency at the sectoral level and across fifteen sub-sectors. The results at the level of entire sectors suggest that the lack of information about energy consumption patterns and about energy efficiency measures, lack of staff time, priority setting within organizations, and - in particular - the investor/user dilemma are all relevant barriers. Allowing for sector-specific differences in the relevance of these individual barriers yields a more heterogeneous picture. The numbers and types of relevant barriers vary across sub-sectors, and the majority of sub-sectors are subject to relatively few barriers. The statistically most significant barriers are found for the sub-sector of public administrations. These findings are robust, independent of whether the definition of an organization's energy efficiency performance includes only measures that have actually been realized or also those that are being planned. For planned projects, however, organizations appear to underestimate internal priority setting as a barrier to energy efficiency.     

Spectral estimation and time-series extrapolation of prime indicators of society

In an effort to determine the cyclic patterns present in the prime indicators of society, Haustein and Neuwirth [3] applied Discrete Fourier Transforms (DFT) to the differences between the logarithmic transformed actual data and selected exponential trend lines. In this paper it is argued that standard DFT analysis is inappropriate for these time series, as is the multiple curve-fitting exercise used to isolate the trends in the data.Instead, the spectral analysis has been redone using a method recently developed by the authors that is appropriate to such limited time-series data. It can detect a periodic signal even if only part of a cycle of that signal is contained within the time-series data. The method also provides an estimation of the time series outside of the original data limits. In addition, single logistic trends are used, and each data set is more carefully screened to ensure approximate stationarity.It is shown that spectral analysis in any form should not be applied to innovation and invention data. Most importantly, the cyclic variations present in world primary energy consumption are also present in world industrial production; this confirms their strong interrelationship. Only the primary energy consumption data series shows stationarity, however, a result that implies a development over time independent of other variables. These two observations suggest that industrial production could be determined from the primary energy consumption, a result that is in direct contrast to the causality generally assumed in an econometric approach to energy forecasting.     

Generalized entropy measures of long-run inequality and stability among male headed households

This paper provides measures of short and long-run inequalities as well as income stability among households with male heads using the panel study of income dynamics for the period 1969–1981. It is found that short-run inequalities have been increasing over the time period examined. Moreover, some fluctuations around this increasing trend are of a transitory nature and appear to be smooth over time. Long-run measures are less subject to fluctuations and provide a better measure of inequality. They show a decrease in inequality in the early periods but increases after the mid-1970's. Several aggregator functions are used to compute permanent income variables for the long-run measures of inequality and stability. The measures are decomposed to reflect differences in age, education, and race. They are decomposed also into groups which are free of such group characteristics. Education has the most important influence on inequality. Stability profiles indicate, furthermore, most of the reduction in inequality in the early periods has been within particular groups. Reductions across groups are minimal.Helpful comments from Esfandiar Maasoumi, Joseph Craycraft, Kenneth Koford and two referees are acknowledged. The usual caveat as to remaining errors applies.     

Determinants of terrorism in Pakistan: An empirical investigation

The purpose of this study is to analyze the determinants of terrorism in the context of Pakistan. The determinants of terrorism include various socio-economic variables like GDP per capita, unemployment, political rights, inflation, poverty, inequality and literacy level. A long-run relationship between the variables is analyzed by applying Johansen co-integration technique. The Error Correction Model (ECM) is applied to determine the stability of the long run relationship between terrorism and various variables and also to streamline the short-run and long run impacts of the variables on terrorism. In general, the results revealed that there exists a long run relationship between various social and economic variables and terrorism while the results of ECM revealed that about 89% convergence towards equilibrium takes place every year. Similarly, important results are obtained by short run and long run elasticities estimated under the Error Correction Model. Impulse response analysis reveals that the impacts of one standard deviation shock given to random disturbances on the systems of variables have mixed results. Some variables have increasing trend over the time period, some have decreasing trends, while some have fluctuating and cyclical trends.

The self-reinforcing dynamics of economic insecurity and obesity

This article models the dynamic effects of economic insecurity on body weight. Using Australian panel data, we infer an individual’s level of economic insecurity as a function of exposure to various financial risks and employ regression equations to explore its effect upon current period body mass index (BMI) scores. Estimates reveal that a sustained standard deviation increase in economic insecurity raises an individual’s BMI at a rate of approximately 0.35 units per year. Quantile regressions are then used to estimate the sensitivity of body weight to insecurity at different percentiles of the distribution and we find that persons who are overweight and obese are much more seriously affected. This implies that shocks that make individuals more financially vulnerable can generate harmful self-sustaining cycles of risk and weight gain. We also model the dynamics of insecurity and show that it is a persistent phenomenon for persons with high levels of exposure and lower incomes. This finding indicates that persons of lower socio-economic status are more likely to encounter vicious cycles of increasing insecurity and obesity, which partially explains why weight-related health problems are unusually highly concentrated amongst these individuals.     

FOOD INSECURITY AND INSUFFICIENCY AT LOW LEVELS OF FOOD EXPENDITURES

In this study we investigate the external validity of the food insecurity and insufficiency measures—specifically, how these measures correlate with food expenditures—using the December 2003 Food Security Supplement of the Current Population Survey. We focus on a special segment of the population—households with low incomes and low food expenditures. If reports of food problems are based on a lack of food, reports should be nearly ubiquitous at the bottom of the expenditure distribution. We find, however, that this is not the case. We define and scale food expenditures several different ways and find that the reported incidence of food insecurity never rises above one‐half anywhere along the corresponding expenditure distributions, leading to concerns about the external validity of the measure.
