Inflation 2024 [PDF]

open access: yesarXiv
Inflation as the leading paradigm depicting the very early universe physics could leave imprints on the cosmic microwave background (CMB) radiation. Using currently available CMB observations, we give the tightest constraints on inflation so far. We discuss the theoretical implications of our results including the energy scale of inflation, inflaton ...

Gravitational Production of Heavy Particles during and after Inflation [PDF]

open access: yesarXiv
We investigate the gravitational production of a scalar field $\chi$ with a mass exceeding the Hubble scale during inflation $m_\chi \gtrsim H_I$, employing both analytical and numerical approaches. We demonstrate that the steepest descent method effectively captures the epochs and yields of gravitational production in a compact and simple analytical ...

Effect of risk and incentives on contracts: The case of farm operators in Iowa

open access: yesAgribusiness, EarlyView.
Abstract Longitudinal data on Iowa landowner–operator contracts are used to examine how the mean, variance, and skewness of expected farmland returns affected contract terms from 2008 to 2019. To control for unobserved operator risk preferences and ability as a fixed effect, the sample includes operators with multiple contracts.

Determining the influence of belonging to a wine protected designation of origin on profitability

open access: yesAgribusiness, EarlyView.
Abstract To guide consumers, wineries need credible attributes about the quality of their wines and its origin. In Spain, protected designations of origin (PDO) guarantee that the wine has been produced in a certain wine region in accordance with specific and officially regulated quality criteria thus providing elements of guarantee to the consumer ...
