Avusturya Okulu Bilgi Teorileri Ve E‐Ticaret Çerçevesinde Akerlof’un Limon Piyasa Modeli‐ nin Değerlendirilmesi

Bu çalışma, piyasalarda güven ve itibarın önem ve gelişim sürecini internet piyasasının teorik bir analizi ile anlatmaktadır. Piyasaların fonksiyonel etkinliği için gerekli olan işbirliği, eBay başta olmak üzere değişik internet piyasası örnekleri kullanılarak tartışılmaktadır. Çıkış noktası olarak Akerlof’un “limon modeli” kullanılarak hem bireylerin piyasalarda işbirliği eğiliminde oldukla‐ rı hem de basit güven ağları başarısızlığı duru‐ munda işbirliği sağlayan piyasaların sağlam yapısı gösterilmektedir. Bu anlamda asimetrik bilginin piyasa başarısızlığına yol açtığını öne süren Akerlof’un yaklaşımının tersine, piyasaların dinamik karakteri işbirliği ve güvenilir taahhütler sağlayabilir sonuçlar ortaya çıkarabilmektedir.

The Evaluation of Akerlof's Lemon Market Model within the Frame of Austrian Informa‐ tion Theories and E‐Trade

This article describes the importance and evolu‐tion of trust and reputation in markets with a theoretical analysis of Internet markets. The cooperation required for markets to function efficiently is discussed using theoretical exam‐ples of various Internet markets, most notably, eBay. Using Akerlof’s lemons model as a point of reference, the author demonstrates both the proclivity for indivuduals to act cooperatively in markets and the robust nature of markets at eliciting cooperation when simple trust Networks fail. Contrary to Akerlof’s assertion that asym‐metric information leads to market failure, the dynamic nature of markets elicits cooperation and credible commitments.
