Food price increases stem from economic, agricultural, and political factors. Understanding the dynamics behind the food price formation process and assessing how potential factors contribute to food price changes will significantly affect policies formulated to manage food price increases. High food inflation rates have been a chronic problem in Turkey over the last decade, with unprocessed food prices rising faster than general price levels. In this article, we use exploratory analyses based on economic principles rather than econometric analyses. First, our results indicate that exchange rates are strongly associated with domestic food prices due to dependence on imported inputs. Second, deep-dive analyses on select products show that global price movements and pass-through prices from producer to consumer are not solely responsible for price increases.

Existing empirical evidence on the impact of macroeconomic variables on agriculture remains mixed and inconclusive. This paper re-examines the dynamic relationship between monetary policy variables and agricultural prices using alternative vector autoregression (VAR) type model specifications. Directed acyclic graph theory is proposed as an alternative modeling approach to supplement existing modeling methods. Similar to results in other studies, this study's findings show that over the time period analyzed (1975–2000), changes to money supply as a monetary policy tool had little or no impact on agricultural prices. The primary macroeconomic policy instrument that affects agricultural prices is the exchange rate, which is shown to be directly linked to interest rate, a source of monetary policy shock.

This article examines the impacts of monetary policy on agricultural prices in four Asian economies using time series analysis and graph theory. The estimations clearly show that agricultural prices overshoot their long-run equilibrium values for Korea, Philippines, and Thailand, and the overshooting for agricultural prices is larger than for manufactured prices. Impulse-response functions and variance-decomposition analysis based on directed graphs and causal structures highlight the complex interplay among the variables in the model and how those relationships differ by country. Money supply changes clearly affect real variables and relative prices for all countries either through overshooting or non-neutrality of money.

The increasing use of agricultural contracts and processor concentration raises concerns that processors may offer lower contract prices in absence of local competition. This study examines the price competitiveness of marketing and production contracts depending on the availability of alternative marketing options. A propensity score matching method is used to compare prices using contract data from a farm-level national survey. The results show that the absence of other contractors or spot markets in producers' areas does not lead to statistically significant price differences in agricultural contracts for most commodities, providing evidence that most agricultural processors do not exercise market power by reducing prices when other local buyers are not available.

Historically, market situation and outlook has often included some form ofprice forecast. Recent volatility in agricultural commodity markets ismaking price forecasts challenging and at times less reliable. In addressingthis price volatility, changes in agricultural markets are highlighted alongwith price forecasts: pre- and postincreased market volatility. Given theserecent challenges, the future of Extension agricultural commodity marketingis discussed.

The aim of this article is to measure the advance of agricultural productivity in South Navarra between 1780 and 1900. The construction of several indices of agricultural commodities and factor prices allows us to apply the methodology of Total Factor Productivity (TFP). As distinguished from the thesis of stagnation, our estimate of the annual rate of TFP growth in the long run is close to 0.42 %. This rate was particularly high between 1817 and 1850, in a context of deflation and institutional change. During the second half of the century the cyclical evolution of the curve reveals the obstacles derived from the capital resources supply, especially fertilizers and animal traction.

This study aims to answer whether empirical records confirm the existence of a secular decline in the terms of trade affecting primary producers (the Singer–Prebisch hypothesis). The paper analyses the evolution of the terms of trade for agricultural and food products in the second half of the 20th century. We obtain sixty new real price indices for internationally traded agricultural products. We conclude, from a long-term perspective, that the deterioration in the terms of trade for agricultural and food products was strong and clear in the second half of the last century. In general, less processed products suffered a very heavy fall in their real prices. However, there was no continuous and persistent deterioration in the terms of trade either as a whole or for the great majority of the agricultural and food product groups (with the exception of natural rubber, textile fibres and other raw materials). Rather, this deterioration occurred in stages.

Economists often assume that agricultural markets in history were competitive, and all producers received the same price. In contrast, most agricultural historians deem prices to differ among agents, according to their social status and «power». This paper tests these opposite views with a database of some 12,500 transactions for the São Paulo area in Brazil in the first decades of the 19th century. Prices received by farmers were positively related to total sales, a proxy for the size of the estate, and also to the share on the relevant market, which measures the market power. These results are consistent with the anecdotal evidence about the growing importance of large slave estates which, however, did not wipe out small household farms.
