This paper presents a version of the proportionally calibrated almost ideal demand system (PCAIDS) model, useful for merger simulations, which can be econometrically estimated using price data for two firms in a market. The model is then applied to a database of the Argentine gasoline market, and its results are compared to the ones obtained with other alternative specifications. JEL Classifica...

Applying the Foster, Haltiwanger, and Krizan (2001) decomposition to plant-level manufacturing data from Chile Korea, we find that entry exit of plants account for a larger fraction aggregate productivity growth during periods fast GDP growth. To analyze this relationship, develop model firm based on Hopenhayn (1992). When introduce reforms reduce costs or barriers technology adoption into cali...

We estimated dry matter digestibility and intake (DMI) in wapiti hinds using the double n-alkane method. We also assessed intra-ruminal controlled-release devices (CRD) for administering n-alkane markers C32 and C36. Nine wapiti hinds were offered alfalfa-based compounded diet for ad libitum consumption and actual DMI was measured daily (mean: 9.2 1.6 kg DM/day). The DMI estimate for C33:C32 (9...

Two new long-chain C33 polyacetylenic compounds, halicynones A and B were isolated from the marine sponge Haliclona sp. along with known analogs. The known compound pellynol A possessing a 1-yn-3-ol terminus, exhibited strong antitumor activity against the human colon tumor cell line HCT-116 (IC50 0.026 μg/mL), however, the corresponding 1-yn-3-one, halicynone A, was inactive, which suggests an...

We consider the estimation of the usual Gravity model of trade, which involves flows of trade, say exports, from country i to country j in time period t. We suggest an easy-to-impliment generalised method of moments estimator that avoids the issues associated with the usual fixed effects treatment of the unobserved heterogeneity in this type of models and at the same time provides consistent pa...

This paper introduces model specifications that can be used to explain response incentive effects that might occur with discrete response contingent valuation data when follow-up responses are collected. The models allowfor possible random response shocks, structural ships in willingness to pay betweenpayment questionsand heteroskedasticity between and within responses. Three well-known conting...

The province of Aceh in Indonesia provides a promising case for studying the economic legacy effects conflict given subnational district-level data on violence and gross domestic product. We demonstrate specific negative armed despite general peace dividend: whilst all districts grow faster after ends 2005 than during conflict, that suffered relatively more from war slowly peacetime experienced...

Thermal expansion of MAX phases along different directions tends to be because the anisotropy hexagonal crystals. Herein, a new Hf2SeC phase was synthesized and confirmed relatively isotropic, coefficients thermal (CTEs) c were determined 9.73 μK−1 10.18 μK−1, respectively. The strong MS bond endowed Hf2SC Zr2SC lower CTEs than those Zr2SeC. relationship between ratio elastic stiffness constant...

Recently Acemolgu, Aghion, Bursztyn and Hemous (AER 2012) formulated a model in which a high macroeconomic elasticity of substitution between clean and dirty production represents a crucial condition for green growth. Until now it has never been systematically estimated. Using a novel panel of cross-country sectoral data, we formulate specifications of nested CES production functions that allow...
