Transient susceptibility to interference at event boundaries impacts long-term memory of naturalistic episodes
During ongoing narratives, event boundaries trigger processes relevant for subsequent memory. Previous work has shown that novel, unrelated input presented at an event boundary can retroactively interfere with short-term retention of the preceding event. This interference was attributed to a perturbation of offset-related processes taking place within seconds after encoding and supporting the binding of elements into a coherent event memory. Howe…
Behavioural interference at event boundaries reduces long-term memory performance in the virtual water maze task without affecting working memory performance
Narrative episodic memory of movie clips can be retroactively impaired by presenting unrelated stimuli coinciding with event boundaries. This effect has been linked with rapid hippocampal processes triggered by the offset of the event, that are alternatively related either to memory consolidation or with working memory processes. Here we tested whether this effect extended to spatial memory, the temporal specificity and extent of the interference…
R&D Investment, Exporting, and Productivity Dynamics
This paper estimates a dynamic structural model of a producer's decision to invest in R&D and export, allowing both choices to endogenously affect the future path of productivity. Using plant-level data for the Taiwanese electronics industry, both activities are found to have a positive effect on the plant's future productivity. This in turn drives more plants to self-select into both activities, contributing to further productivity gains. Simula…
Productivity, Output, and Failure
We use micro panel data for producers in seven two-digit manufacturing industries in South Korea and Taiwan and identify a number of systematic differences in industry structure between the countries. Our empirical findings indicate Taiwanese industries are characterised by less concentrated market structure, more producer turnover, smaller within-industry productivity dispersion across producers, a smaller percentage of plants operating at low p…
Firm-level evidence on productivity differentials and turnover in Taiwanese manufacturing
The Long-Run Demand for Skilled and Unskilled Labor in Colombian Manufacturing Plants
This note estimates the long-run demand for skilled and unskilled labor using panel data for Colombian manufacturing plants. Unobserved heterogeneity and measurement error problems that commonly arise in microdata production estimates are examined. Output measurement errors cause OLS estimators to underestimate the output and wage response of employment demand. Time-difference estimators exaggerate the measurement error biases. Instrumental-varia…
The Duration of Employment Opportunities in U.S. Manufacturing
Long-duration employment opportunities are a necessary condition for workers to hold lifetime jobs. This paper uses longitudinal data on individual U.S. manufacturing plants from 1963-1982 to estimate the age and completed spell distributions for employment positions. The results indicate that, of the employment opportunities in progress in the U.S. manufacturing sector in 1982, 30.0% were at least 19 years old and 59.6% would have a completed le…
The Growth and Failure of U. S. Manufacturing Plants
This paper examines the patterns of postentry employment growth and failure for over 200,000 plants that entered the U. S. manufacturing sector in the 1967–1977 period. The postentry patterns of growth and failure vary significantly with observable employer characteristics. Plant failure rates decline with size and age as do the growth rates of nonfailing plants. The expected growth rate of a plant, which depends on the net effect of these two fo…
Patterns of Firm Entry and Exit in U.S. Manufacturing Industries
This article summarizes the patterns of firm entry, growth, and exit in the four-digit U.S. manufacturing industries over the period 1963-1982. Entrants are disaggregated into new firms, existing firms that diversify into an industry by opening new production facilities, and existing firms that enter by altering the mix of outputs they produce in their existing plants. We examine the relative importance of different types of entrants, the persist…
Cost-Minimizing Regulation of Sulfur Emissions
Environmental regulations set maximum allowable rates for sulfur dioxide emissions from electric utilities. By ignoring firm differences in marginal abatement costs and preventing emissions trading, these standards do not minimize the cost of reducing einissions. This paper estimates marginal abatement cost functions for 56 utilities for 1973-79. Marginal costs vary substantially across firms due to differences in the price of low and high sulfur…
The Role of Imports from the Newly-industrializing Countries in U.S. Production
This paper examines the relationship among U.S. imports from the NICs, imports from developed countries, capital, and labor in the production of goods for final demand. Import demand and substitution elasticities are estimated for the period 1960-80. U.S. imports from the NICs are found to be complements with both labor and imports from industrialized countries. This indicates that the substitution effect resulting from a reduction in the price o…
Environmental Regulations and Productivity Growth
This paper measures and analyzes the effect of sulfur dioxide emission restrictions on the rate of productivity growth in the electric power industry over the 1973-79 business cycle. A firm-specific measure of regulatory intensity is developed which depends on the severity of the emission standard, the extent of enforcement, and the unconstrained emission rate relevant to each utility. The results indicate that emission regulations result in sign…
