We use time series techniques to estimate the importance of four main explanations for decline US labor income share: rising firm markups, falling bargaining power workers, higher investment-specific technology growth, and more automated production processes. Identification is achieved with restrictions derived from a stylized model structural change. Our results point automation as driver shar...

Helisoma trivolvis embryos display a cilia-driven rotational behavior that is regulated by a pair of serotonergic neurons named ENC1s. As these cilio-excitatory motor neurons contain an apical dendrite ending in a chemosensory dendritic knob at the embryonic surface, they probably function as sensorimotor neurons. Given that nitric oxide (NO) is often associated with sensory neurons in inverteb...

We report the complete genome sequence of a lineage I peste des petits ruminants virus (E32/1969) isolated in a Senegalese laboratory in 1969. This is the earliest peste des petits ruminants virus of any lineage sequenced to date and only the second lineage I virus available in public databases.

This paper compares Kaleckian and Harrodian models of accumulation. The simplicity of the canonical Kaleckian model is appealing but more complex Harrodian speci…cations are preferable from a behavioral perspective. The local instability of Harrodian-inspired speci…cations, moreover, o¤ers a uni…ed understanding of both trend and cycles. JEL classi…cation: E12, E32, O41

In this paper, I find that real U.S. GDP is better characterized as a trend stationary Markov-switching process than as having a (regime-dependent) unit root. I examine the effects of both assumptions on the analysis of business cycle features and their implications for the persistence of the dynamic response of output to a random disturbance.

When capacity utilization is allowed to vary, standard equilibrium theory predicts that demand shocks can generate not only closed-economy business cycles that are previously thought explainable only by technology shocks, but also international business cycles that are more consistent with the data than what can be generated by technology shocks.

The interaction between income distribution, accumulation, employment and the utilization of capital is central to macroeconomic models in the `heterodox' tradition. This paper examines the stylized pattern of these variables using US data for the period after 1948. We look at the trends and cycles in individual time series and examine the bivariate cycical patterns among the variables. JEL cla...

We have previously reported that serial truncation of the Gag p9 protein of equine infectious anemia virus (EIAV) revealed a progressive loss in replication phenotypes in transfected cells, such that a proviral mutant (E32) expressing the N-terminal 31 amino acids of p9 produced infectious virus particles similarly to parental provirus, while a proviral mutant (K30) with two fewer amino acids p...

The standard linear technique of impulse response function analysis is extended to the nonlinear case by de"ning a generalized impulse response function. Measures of persistence and asymmetry in response are constructed for a wide class of time series. ( 2000 Elsevier Science B.V. All rights reserved. JEL classixcation: C22; C51; C52; E32
