We consider the situation in which there are multiple proxies for one unobserved explanatory variable in a linear regression and provide a procedure by which the coefficient of interest can be extracted "post hoc" from a multiple regression in which all the proxies are used simultaneously. This...

Regarding the trade-off between the depth and the duration of recessions, there exists a mounting empirical evidence of … GDP in depth and a relative difference of 3 years duration can be attributed to this parameter. Overlooked for decades …

We complement the theory of tick-by-tick dynamics of financial markets based on a continuous-time random walk (CTRW) model recently proposed by Scalas et al [4], and we point out its consistency with the behaviour observed in the waiting-time distribution for BUND future prices traded at LIFFE,...

We investigate why we observe non-negative duration dependence among young unemployed men in urban Ethiopia. Assuming … that genuine duration dependence is negative, there are five explanations for a non-decreasing hazard: the presence of … is the only convincing one. We also establish that genuine duration dependence is indeed negative in the long run. …

Unemployment is concentrated among relatively … well-educated first time job seekers who come from the middle classes. Mean duration of unemployment is close to four years … Addis are less likely to become unemployed, and ethnicity has no effect. We find that both the incidence and duration of …
