A key aspect of online social networks (OSNs) is the user-generated multimedia content shared online. OSNs like Facebook have to deal with up to 300 million photos uploaded on a daily basis, both videoand audio-related social networks have also started to gain important shares of the market. Although the security and privacy mechanisms deployed by OSNs can cope with several risks and discourage...

Social media websites have dramatically increased in popularity. Information on these sites does not require verification and may be inaccurate. We investigated how familiarity with content and Twitter authors influenced false memory. Participants from Michigan State University (MSU) read an article about college basketball followed by a Twitter recap that contained false information. The artic...

This paper studies the impact of tax-financed universal health coverage schemes on macroeconomic aspects of labor supply, asset holding, inequality, and welfare, while taking into account features common to developing economies, such as informal employment and tax avoidance, by constructing a dynamic stochastic general equilibrium model with heterogeneous agents. Agents have different education...

A market anomaly (or market inefficiency) is a price distortion typically on a financial market that seems to contradict the efficient-market hypothesis. Such anomalies could be calendar, technical or fundamental related and have been shown empirically in a number of settings for financial markets. This paper extends this stream of research to two-sided auction platforms in Electronic Commerce ...

In this paper we consider an overlapping generations model with endogenous fertility and two-sided altruism and show the limitations of applying commonly used open loop Nash equilibrium in characterizing equilibrium transfers from parents to children in the form of bequest, and transfers from children to parents as voluntary old-age support. Since in our model children are concerned with parent...

Isoperimetric inequalities measure the complexity of the word problem in finitely presented groups by giving a bound on the number of relators that one must apply in order to show that a word w in the given generators represents the identity. Such bounds are given in terms of the length of w, and the function describing the optimal bound is known as the Dehn function of the group. (Modulo a sta...

We present a dynamic OLG model of educational signaling and inequality with missing credit markets. Agents are characterized by two sources of unobserved heterogeneity: ability and parental income, consistent with empirical evidence on returns to schooling. Both quantity and quality of human capital evolve endogenously. The model generates a Kuznets inverted-U pattern in skill premia similar to...

We previously introduced a new Bayesian predictive classification (BPC) approach to robust speech recognition and showed that BPC is capable of coping with many types of distortions. We also learned that the efficacy of the BPC algorithm is inflEenced by the appropriateness of the prior distribution for the mismatch being compensated. If the prior distribution fails to characterize the variabil...

Multinational firms circumvent capital controls by distorting their reported trade patterns, profitability, and dividend repatriations. The changed patterns of reported profits in response to capital controls are comparable to the effects of a 24% difference in corporate tax rates. The costliness of these acts of evasion combined with the significantly higher interest rates faced by multination...

We explore if traditional sharing norms in extended kinship systems distort consumption and accumulation decisions of poor black households in Kwazulu-Natal, South Africa. Our results suggest households try to evade their “sharing obligations” by (i) accumulating durables that are non-sharable at the expense of durables that may be shared, (ii) increasing consumption of non-durables, and (iii) ...
