This paper provides an introduction and “user guide” to Regression Discontinuity (RD) designs for empirical researchers. It presents the basic theory behind research design, details when RD is likely be valid or invalid given economic incentives, explains why it considered a “quasi-experimental” summarizes different ways (with their advantages disadvantages) of estimating limitations interpreting these estimates. Concepts are discussed using examples drawn from growing body RD. (JEL C21, C31)
This paper empirically assesses the wage effects of Job Corps program, one largest federally funded job training programs in U.S. Even with aid a randomized experiment, impact program on wages is difficult to study because sample selection, pervasive problem applied microeconometric research. Wage rates are only observed for those who employed, and employment status itself may be affected by program. develops an intuitive trimming procedure bounding average treatment presence selection.

We estimate the effect of new private-sector unionization on publicly traded firms' equity value in United States over 1961–1999 period using a newly assembled sample National Labor Relations Board (NLRB) representation elections matched to stock market data. Event-study estimates show an average union firm equivalent $40,500 per unionized worker, that takes 15 18 months after fully materialize, and one could not be detected by short-run event study. At same time, point from regression...
ORDER TO PROVE PROPOSITION 1, we first present and prove the following lemmas.Suppose ϕ(x t) its partial derivative, ϕ 2 (x t), are continuous that is integrable with respect to probability measure α for each t.Then f (t) = dα(x) continuously differentiable on [c d].
Social media use has become an integral part of many young adults' daily lives. Although much research examined how social relates to psychological well-being, little is known about it physical health.

Nearly all require people find extract relevant perceptual information from their environment, but demands this nature are often ignored study mental effort.

In efforts to curb the spread of COVID-19, many countries have implemented a variety lockdown and quarantine measures. With substantially reduced face-to-face interactions, people may relied heavily on social media for connection, information, entertainment.
