Economic insecurity describes the risk of economic loss faced by workers and households as they encounter the unpredictable events of social life. Our review suggests a four-part framework for studying the distribution and trends in these economic risks. First, a focus on households rather than workers captures the microlevel risk pooling that can smooth income flows and stabilize economic well-being. Second, insecurity is related to income volatility and the risk of downward mobility into poverty. Third, adverse events such as unemployment, family dissolution, or poor health commonly trigger income losses. Fourth, the effects of adverse events are mitigated by insurance relationships provided by government programs, employer benefits, and the informal support of families. Empirical research in these areas reveals high levels of economic insecurity among low-income households and suggests an increase in economic insecurity with the growth in economic inequality in the United States.

Abstract
Difficulties related to the problem of evaluating the economic security / insecurity, including the threshold of economic security / insecurity, namely the impossibility of giving an analytical description of a criterion entirely made up of a set of indicators describing the degree of economic security / insecurity, makes more and more researchers, including the authors, to seek indirect ways of finding solutions, for example considering systemic risk., as a measure of evaluation. Thus, starting from a new approach, and given the specific components of systemic risk to financial stability: the banking sector, corporate sector, public sector, volume of credits, economic activity index the threshold vector of economic security / insecurity can be developed. The study shows that systemic risk can be used to measure the threshold of economic security /insecurity.

The principal concern of this paper is with the need of a theoretical shift in economics for analyzing and devising efficient and innovative policy reforms to combat employment insecurity. Mainstream economics is unable to provide appropriate theorizing about economic phenomena, including economic insecurity. Thus, we must turn to economic theories which radically question the dominant paradigm in economics. John Rogers Commons's institutionalist theory accomplishes that. First, the author of this paper outlines the distinctive character of this theory by presenting some of its crucial methodological differences with neoclassical economics. Second, she explains how economic insecurity is conceptualized as an "instituted" process with this theory of institution. A better mastery of this specific school of thought in economics appears to escape the problems met by mainstream economics by proposing a real theoretical alternative for the development of a truly evolutionary, trans-disciplinary and ethical economic theory.

A central question in the international and comparative political economy literatures on globalization is whether economic integration increases worker insecurity in advanced economies. Previous research has focused on the role of international trade and has failed to produce convincing evidence that such a link exists. In this article, we argue that globalization increases worker insecurity, but that foreign direct investment (FDI) by multinational enterprises (MNEs) is the key aspect of integration generating risk. FDI by MNEs increases firms' elasticity of demand for labor. More‐elastic labor demands, in turn, raise the volatility of wages and employment, all of which tends to make workers feel less secure. We present new empirical evidence, based on the analysis of panel data from Great Britain collected from 1991 to 1999, that FDI activity in the industries in which individuals work is positively correlated with individual perceptions of economic insecurity. This correlation holds in analyses accounting for individual‐specific effects and a wide variety of control variables.
