We try to examine the potential of input–output price model to identify mechanisms of price formation and transmission. Contrary to previous research that focused on overcoming the specific limitations of the model, we test its overall performance. In the presented study, the historical values of the commonly used consumer price index were decomposed according to the classic input–output price model for an open economy. A sequence of ex post simulations under various assumptions was used to identify the sources of inflation. This study required the use of input–output tables in current and previous year’s prices. The proposed method of decomposition might be a starting point to create a framework for studying different aspects of inflation process.

This paper examines the welfare effect of third-degree price discrimination in a vertically related market with one upstream monopolist that sells its input to a continuum of downstream markets. Assume that the market boundary of the monopolist is endogenously determined. It is found that social welfare is necessarily lower under discriminatory than uniform pricing, even if the market area of the former is greater than that of the latter. This finding is contrary to that in the extant literature on price discrimination in final goods markets.

Drawing on uncommonly rich and representative data from the Colombian manufacturing census, this paper documents new empirical relationships between input prices, output prices, and plant size and proposes a model of endogenous input and output quality choices by heterogeneous firms to explain the observed patterns. The key empirical facts are that, on average within narrowly defined sectors, (1) larger plants charge more for their outputs and (2) larger plants pay more for their material inputs. The latter fact generalizes the well-known positive correlation between plant size and wages. Similar correlations hold between prices and export status. We show that the empirical patterns are consistent with a parsimonious extension of the Melitz (2003, \"The Impact of Trade on Intra-Industry Reallocations and Aggregate Industry Productivity,\" Econometrica, 71, 1695-1725) framework to include endogenous choice of input and output quality. Using a measure of the scope for quality differentiation from Sutton (1998, Technology and Market Structure: Theory and History. Cambridge: MIT Press), we show that differences across sectors in the relationships between prices and plant size are consistent with our model. Available evidence suggests that differences in observable measures of market power do not provide a complete explanation for the empirical patterns. We interpret the results as supportive of the hypothesis that quality differences of both inputs and outputs play an important role in generating the price-plant size correlations.

We present a model that explains the relationship between low input prices, high exit rates, and industrial concentration. We argue that falling input prices force less productive firms to exit the market, and lead to the expansion of more efficient incumbents at the expense of less productive producers. Our model helps reconcile some well-established empirical results regarding the food processing industry. Indeed, agricultural prices fell between the early 1900s and 2006, and over the same period there was a trend towards higher concentration in the food industry, with an increase in average productivity.

This paper examines some of the recent literature on the estimation of production functions. We focus on techniques suggested in two recent papers, Olley and Pakes (1996) and Levinsohn and Petrin (2003). While there are some solid and intuitive identification ideas in these papers, we argue that the techniques can suffer from functional dependence problems. We suggest an alternative approach that is based on the ideas in these papers, but does not suffer from the functional dependence problems and produces consistent estimates under alternative data generating processes for which the original procedures do not.

New goods play a central role in many trade and growth models. We use detailed trade and firm-level data from India to investigate the relationship between declines in trade costs, imports of intermediate inputs, and domestic firm product scope. We estimate substantial gains from trade through access to new imported inputs. Moreover, we find that lower input tariffs account on average for 31% of the new products introduced by domestic firms. This effect is driven to a large extent by increased firm access to new input varieties that were unavailable prior to the trade liberalization.

In this paper, we empirically investigate whether trade liberalization affects markup dispersion, a potential source of resource misallocation. The identification uses China's WTO accession at the end of 2001. We show that trade liberalization reduces markup dispersion within a narrowly defined industry. We also examine both price and cost responses to trade liberalization, as well as heterogeneous effects across firms and across locations. Our study contributes to the literature by identifying another potential channel through which free trade benefits a nation.

Using input–output data from Symmetric Input–Output Tables for the year 2010 and relevant price models, this paper provides empirical estimations of medium- and long-run effects of wage and currency devaluations on international price competitiveness and income distribution for two ‘PIIGS economies’, i.e. Greece and Italy. The findings reveal certain differentiated socio-technical production conditions in the economies under consideration casting doubt on the effectiveness of demand-switching policy measures implemented in the post-2010 Eurozone economy. At the same time, however, wage devaluation is found to be a comparatively slow and inefficient process to improve international price competitiveness in the medium-run.

Price discrimination has substantial social and policy implications and has received attention in the literature. However, prior research on input price discrimination has primarily been limited to single-input situations. We explore the strategic desirability of uniform pricing and contribute to the growing literature on perfectly complementary inputs in vertical markets. We consider a vertically related market in which two symmetric upstream firms provide perfectly complementary inputs for two downstream manufacturers, one of which has a non-controlling interest in its rival. Each upstream firm can choose between two pricing regimes: discriminatory or uniform. This study shows that although uniform pricing limits the firm’s flexibility, one upstream firm voluntarily chooses uniform pricing, and the other chooses discriminatory pricing in equilibrium. Furthermore, in the mixed-strategic equilibrium for the pricing regimes, we find that downstream horizontal shareholding makes upstream firms likely to choose uniform pricing, which is undesirable for consumers and society. We extend the above analysis to the following directions: endogenous horizontal shareholding and two-part tariffs.

We measure the impact of a drastic new technology for producing steel—the minimill—on industry-wide productivity in the US steel industry, using unique plant-level data between 1963 and 2002. The sharp increase in the industry's productivity is linked to this new technology through two distinct mechanisms: (i) the mere displacement of the older technology (vertically integrated producers) was responsible for a third of the increase in the industry's productivity, and (ii) increased competition, due the minimill expansion, drove a productivity resurgence at the surviving vertical integrated producers and, consequently, the productivity of the industry as a whole.
