Capital-labor substitution elasticity: A simulated method of moments approach
No full textThe elasticity of substitution between capital and labor plays an important role in the analysis of economic and policy issues such as factors\u27 share in national income and tax policies on business capital formation. Rather than focusing on long-run relationships to estimate this elasticity, I exploit the short-run variations in the labor income share due to changes in capital-embodied technology. Using the simulated method of moments approach, I obtain an elasticity estimate that is clearly less than one. The study indicates that estimates based on the long-run relationship of factor\u27s share may tend to be significantly larger
The labour income share and the relative price of investment in the US: an empirical investigation
No full textSeveral studies argue that the recent decline in the secular trend of the labour income share is mostly driven by capital-embodied technological progress which is typically identified with trend reductions in the relative price of investment. In this paper, I use data from the United States to assess the nature of the relationship between trends in the labour share and the relative price of investment. Results from co-integration tests reveal that the share and the relative price of investment are most likely not co-integrated. However, co-variation tests indicate that both time series share a common stochastic component, and additional tests of structural breaks point at the presence of a common change in the mean or trend of both series. These results suggest that capital-embodied or investment-specific technological progress may have played an important role in the decline of the secular trend of the labour share
An unobserved components model of total factor productivity and the relative price of investment
No full textThis paper applies the common stochastic trends representation approach to the time series of total factor productivity (TFP) and the relative price of investment (RPI) to investigate the modeling of neutral technology (NT) and investment-specific technology (IST) and its econometric ramifications on the analysis of general equilibrium model. The permanent and transitory movements in both series are estimated efficiently via Markov chain Monte Carlo methods using band matrix algorithms. The results indicate that TFP and the RPI are, each, well represented by a differenced first-order autoregressive process. In addition, their time series share a common trend component that we interpret as reflecting changes in general purpose technology. These results are consistent with studies that suggest that (1) the traditional view of assuming that NT and IST follow independent processes is not supported by the features of the time series and (2) improper specification of secular trends may distort estimation and inference. Notably, the findings provide some guidance to minimize the effect of idiosyncratic and common trend misspecifications on the analysis of impulse dynamics and propagation mechanisms in macroeconomic models
Investment-specific technological changes: The source of long-run TFP fluctuations
No full textTechnological innovations originating in the capital-producing sector may spillover to the rest of the economy and enhance aggregate TFP in the long-run. This paper assesses the quantitative importance of investment-specific technological changes in long-run movements in aggregate TFP. To this end, we construct a two-sector business cycle model where an IST diffusion process influences long-run movements in aggregate TFP via spillover. We then establish the linkage between the primitive shocks of the model and two shocks that can be identified from a VAR approach: one shock accounting for the long-run movement in aggregate TFP and the other accounting for the long-run movement in the inverse of the relative price of investment. We show analytically that the correlation of these two long-run shocks can be fruitful in distinguishing the quantitative importance of IST innovations in long-run movements in aggregate TFP. Using post-war U.S. data, we find that these two long-run shocks identified by the MFEV approach are almost perfectly collinear. Moreover, these two shocks can explain a significant, and surprisingly similar, fraction of the business-cycle fluctuations in other important macro variables. Our findings suggest that embodied technological changes are an important driver of long-run movements in aggregate TFP
Output measurement and technological shocks in business cycles
No full textIs the importance of technology shocks in accounting for the fluctuations in output and hours sensitive to the measure of output? Using a vector autoregression, we empirically investigate the contribution of technological shocks to economic fluctuations when output is defined in consumption units, as commonly used in many macroeconomic models, and when output is tabulated according to the Divisia index in the U.S. National Income and Product Accounts (NIPAs). Based on a standard neoclassical growth framework that allows for a mapping of theory into any desired measure of output, we establish that the same restrictions may be used to identify technology shocks in a vector autoregression model regardless of the measure of output. However, our estimation reveals that while the combination of both investment-specific technology shocks and neutral technology shocks accounts for a large portion of the business cycle variability of hours and output, the choice of the measure of output via the use of the associated deflator greatly affects the amplification of the shocks in the responses and the variability of the responses in output and hours. © 2023 Informa UK Limited, trading as Taylor & Francis Group

Edouard Vuillermoz and Dix Pièces Mélodiques
No full textabstract: ABSTRACT
Edouard Vuillermoz (1869-1939) was a horn player and teacher who studied and later taught at the Paris Conservatory during the early twentieth century. As did many of the professors from the Conservatory, Vuillermoz published works for the horn. Unfortunately, his name has largely faded into obscurity and most of his works are no longer in print, yet one has remained in the repertoire and is still available for purchase today—Dix Pièces Mélodiques. Published in 1927 by Alphonse-Leduc, Vuillermoz desired for his students a set of etudes that would teach mastery of transposition, but he was not a composer. The ten transposition exercises he created were selected and transcribed from a compilation of vocalises commissioned by a vocal professor at the Conservatory, Amédée-Louis Hettich (1856-1937).
Hettich desired vocalise-etudes that would able aid and inspire his students, so he commissioned over one-hundred-fifty vocalises by modern composers during the first half of the twentieth century. Composers including Bozza, Copland, Dukas, Fauré, Messiaen, Nielsen, Ravel, and Tomasi answered his call for works between 1906 and 1938. These modern vocalise-etudes have since disappeared from the vocal repertoire. Now, a century later, many of these studies have entered the public domain and are resurfacing as instrumental transcriptions and concert etudes. This study promotes awareness of Edouard Vuillermoz’s Dix Pièces Mélodiques and advocates for their inclusion in a modern revival.Dissertation/ThesisDoctoral Dissertation Music 201
S-Nitrosylation in Organs of Mice Exposed to Low or High Doses of γ-Rays: The Modulating Effect of Iodine Contrast Agent at a Low Radiation Dose
No full textThe covalent addition of nitric oxide (NO•) onto cysteine thiols, or S-nitrosylation, modulates the activity of key signaling proteins. The dysregulation of normal S-nitrosylation contributes to degenerative conditions and to cancer. To gain insight into the biochemical changes induced by low-dose ionizing radiation, we determined global S-nitrosylation by the “biotin switch” assay coupled with mass spectrometry analyses in organs of C57BL/6J mice exposed to acute 0.1 Gy of cesium-137 γ-rays. The dose of radiation was delivered to the whole body in the presence or absence of iopamidol, an iodinated contrast agent used during radiological examinations. To investigate whether similar or distinct nitrosylation patterns are induced following high-dose irradiation, mice were exposed in parallel to acute 4 Gy of cesium-137 γ rays. Analysis of modulated S-nitrosothiols (SNO-proteins) in freshly-harvested organs of animals sacrificed 13 days after irradiation revealed radiation dose- and contrast agent-dependent changes. The major results were as follows: (i) iopamidol alone had significant effects on S-nitrosylation in brain, lung and liver; (ii) relative to the control, exposure to 0.1 Gy without iopamidol resulted in statistically-significant SNO changes in proteins that differ in molecular weight in liver, lung, brain and blood plasma; (iii) iopamidol enhanced the decrease in S-nitrosylation induced by 0.1 Gy in brain; (iv) whereas a decrease in S-nitrosylation occurred at 0.1 Gy for proteins of ~50 kDa in brain and for proteins of ~37 kDa in liver, an increase was detected at 4 Gy in both organs; (v) mass spectrometry analyses of nitrosylated proteins in brain revealed differential modulation of SNO proteins (e.g., sodium/potassium-transporting ATPase subunit beta-1; beta tubulins; ADP-ribosylation factor 5) by low- and high-dose irradiation; and (vi) ingenuity pathway analysis identified major signaling networks to be modulated, in particular the neuronal nitric oxide synthase signaling pathway was differentially modulated by low- and high-dose γ-irradiation.Peer reviewe
