Abstract

Price fluctuations, market structure, and price transmission can significantly affect the welfare of egg producers and consumers. The current study aims to evaluate price transmission and analyze its impact on the egg market in the Fars province (April 2016 to December 2021). The market structure was examined using several indices, i.e., the inverse number of firms, concentration ratios, Herfindal-Hirschman index, and Hall-Tiedman index at the pullet breeding and wholesale levels in the egg market. The price transmission between wholesale eggs and retail levels was investigated, employing error correction, threshold autoregressive, and momentum threshold autoregressive models. The results indicated an increasing trend in the average annual changes in the percentage of wholesale and retail prices, with an increase in the standard deviation of average monthly prices. Thus, the results revealed severe fluctuations during this study. Market structure at the pullet breeding and wholesale levels indicated a state of multilateral monopoly and monopolistic competition. Furthermore, the analysis demonstrated asymmetric price transmission from wholesale to retail. Due to the non-competitive market structure and the observed asymmetry in price transmission, egg producers and consumers have to bear higher costs.

Abstract [Persian]

نوسانات قیمتی، ساختار بازار و انتقال قیمت در بازار تخم‌مرغ رفاه تولیدکنندگان و مصرف کنندگان این محصول را به طور قابل ملاحظه‌ای تحت تأثیر قرار می­دهد. هدف این مطالعه ارزیابی انتقال قیمت و اثرات آن در بازار تخم مرغ در دوره‌ی فروردین سال 1395 تا آذر سال 1400 در استان فارس می‌باشد. ساختار بازار بر اساس شاخص­های معکوس تعداد بنگاه، نسبت‌های تمرکز، هرفیندال-هیرشمن (HHI) و هال-تایدمن (HT) در سطوح پرورش پولت و عمده‌فروشی تخم­ مرغ بررسی و تحلیل شد. افزون بر این انتقال قیمت بین سطوح عمده‌فروشی و خرده­فروشی تخم‌مرغ با استفاده از مدل‌های تصحیح خطا، آتورگرسیو آستانه‌ای و آتورگرسیو آستانه‌ای تکانه‌ای بررسی ­شد. نتایج نشان داد که میانگین درصد تغییرات سالانه قیمت‌های عمده‌فروشی و خرده‌فروشی و همینطور انحراف معیار میانگین قیمت‌های ماهانه در هر سال، دارای روندی افزایشی همراه با تشدید نوسانات در دوره مورد بررسی بوده است. ساختار بازار در سطوح پررش پولت و عمده‌فروشی تخم‌مرغ انحصار چندجانبه و رقابت انحصاری است. علاوه‌براین نتایج تحلیل انتقال نامتقارن قیمت از عمده‌فروشی به خرده‌فروشی را نشان داد. بنابراین به دلیل ساختار غیررقابتی بازار و انتقال نامتقارن قیمت، تولیدکنندگان و مصرف‌کنندگان تخم‌مرغ هزینه‌ی بیشتری را می‌پردازند.
