The aftermath of civil war

Using an"event-study"methodology, this paper analyzes the aftermath of civil war in a cross-section of countries. It focuses on those experiences where the end of conflict marks the beginning of a relatively lasting peace. The paper considers 41 countries involved in internal wars in the period 1960-2003. In order to provide a comprehensive evaluation of the aftermath of war, the paper considers a host of social areas represented by basic indicators of economic performance, health and education, political development, demographic trends, and conflict and security issues. For each of these indicators, the paper first compares the post- and pre-war situations and then examines their dynamic trends during the post-conflict period. The paper concludes that, even though war has devastating effects and its aftermath can be immensely difficult, when the end of war marks the beginning of lasting peace, recovery and improvement are indeed achieved.Population Policies,Peace&Peacekeeping,Post Conflict Reintegration,Services&Transfers to Poor,Social Conflict and Violence

The aftermath of Civil War

Using an “event-study” methodology, this paper analyzes the aftermath of civil war in a cross-section of countries. It focuses on those experiences where the end of conflict marks the beginning of a relatively lasting peace. The paper considers 41 countries involved in internal wars in the period 1960-2003. In order to provide a comprehensive evaluation of the aftermath of war, the paper considers a host of social areas represented by basic indicators of economic performance, health and education, political development, demographic trends, and conflict and security issues. For each of these indicators, the paper first compares the post- and pre-war situations and then examines their dynamic trends during the post-conflict period. It conducts this analysis both in absolute and relative terms, the latter in relation to control groups of otherwise similar countries. The paper concludes that, even though war has devastating effects and its aftermath can be immensely difficult, when the end of war marks the beginning of lasting peace, recovery and improvement are indeed achieved.Civil War

What Are the Implications of Rising Debt for Older Americans?

The share of older Americans with debt has been on the rise over the last several decades. Having debt, however, does not always signal financial fragility because debt can be used for various purposes. For example, households that take out a low-interest mortgage to buy a home, which typically appreciates in value, are likely making a savvy choice. In contrast, households that carry unpaid credit card balances could see their debt snowball, leading to financial distress. Identifying these distinctions in household debt situations is crucial to understanding the implications of the rise in debt holding among seniors.  This brief, based on a new paper, addresses three key questions: 1) As more older households carry debt in retirement, what share are at "high-risk" and "low-risk" of financial hardship? 2) Is the growth in debt holding driven by the high- or low-risk households? and 3) What are the different types of high-risk households?The answers will help policymakers determine which types of borrowers are most vulnerable and develop tailored solutions for assisting them.   The discussion proceeds as follows. The first section provides background on trends in debt holding among older Americans. The second section sorts households into high-risk and low-risk based on their debt and asset profiles, and it shows that high-risk borrowers are driving the growth in debt. The third section identifies four groups of high-risk borrowers with very different characteristics. Given the diverse situations of high-risk borrowers, the fourth section suggests some potential ways to address each group's specific needs. The final section concludes that the debt burdens of high-risk borrowers are cause for concern, but a one-size-fits-all solution does not exist, so targeted interventions would be most effective.  Click "Download" to access this resource

The First Zagreb Index, Vertex-Connectivity, Minimum Degree And Independent Number in Graphs

Let G be a simple, undirected and connected graph. Defined by M1(G) and RMTI(G) the first Zagreb index and the reciprocal Schultz molecular topological index of G, respectively. In this paper, we determined the graphs with maximal M1 among all graphs having prescribed vertex-connectivity and minimum degree, vertex-connectivity and bipartition, vertex-connectivity and vertex-independent number, respectively. As applications, all maximal elements with respect to RMTI are also determined among the above mentioned graph families, respectively

Sticky wages, labor demand elasticity and rational unemployment

In this paper we give a clear-cut explanation to the sluggish wage adjustments which are commonly experienced also in face of involuntary unemployment. We prove that unemployment may be the physiological outcome of rational decisions by competing workers who may find it optimal to ask higher wages than the full-employment ones. The key element driving the result is the slope (or elasticity) of labor demand schedule: in case of rigid labor demand, in fact, workers’ wage requests are kept high because of reduced unemployment opportunity costs. This contrasts with other approaches to the analysis of unemployment, where only the level of labor demand is considered. Impatience of working and effort required by the job are also showed to influence the degree of wage stickiness

Long-run consequences of debt in a stock-flow consistent network economy

In this paper we develop a theoretical framework to analyze the long-run behavior of an economy characterized by a regime of persistent debt. We introduce a stock-flow consistent dynamic model where the economic system is represented by a network of trading relationships among agents. Debt contracts are one of such relationships. The model is characterized by a unique and stable steady-state, which predicts that (i) aggregate income is always limited from the above by the money supply and that (ii) debts cause a redistribution of borrowers' wealth and income in favor of lenders. In the aggregate this may also lower nominal income, as empirical evidence suggests

Factor analysis with a single common factor

In this paper we present a simple approach to factor analysis to estimate the true correlations between observable variables and a single common factor. We first provide the exact formula for the correlations under the orthogonality conditions, and then we show how to consistently estimate them using a random sample and a proper instrumental variable

Emerging Applications of Reversible Data Hiding

Reversible data hiding (RDH) is one special type of information hiding, by which the host sequence as well as the embedded data can be both restored from the marked sequence without loss. Beside media annotation and integrity authentication, recently some scholars begin to apply RDH in many other fields innovatively. In this paper, we summarize these emerging applications, including steganography, adversarial example, visual transformation, image processing, and give out the general frameworks to make these operations reversible. As far as we are concerned, this is the first paper to summarize the extended applications of RDH.Comment: ICIGP 201
