Distinta dalla garanzia per mancanza di qualità:&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
2 vizi:&lt;span style=&quot;mso-spacerun: yes;&quot;&gt;&amp;nbsp; &lt;/span&gt;inidonea
all’uso; diminuzione in modo apprezzabile del valore (bisogna farlo notare
subito).&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
Alcuni beni difficilmente sono inidonei all’uso (es:
divano). Questa garanzia copre i vizi Occulti, quindi difficilmente
riconoscibili (1491). &lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
Esclusa se il compratore conosceva i vizi o se erano
facilmente riconoscibili, salvo se il venditore dichiara che sono esenti da
rischi. I vizi apparenti, delle cose trasportate, con il compratore che non ha
potuto osservare prima, sono coperti da garanzia.&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
Il compratore ha l’onere di controllare la merce.&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
Tra gli imprenditori e commercianti, l’onere di diligenza
sarà maggiore rispetto ai consumatori.&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
La garanzia può essere esclusa o limitata (1490, comma 2),
non ha effetto l’esclusione se il venditore ha taciuto in malafede i vizi
dell’oggetto.&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
Se il compratore si accorge che il bene è viziato può fare :&amp;nbsp;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
1)
richiesta risoluzione contratto;&amp;nbsp;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
2) richiesta riduzione prezzo;&amp;nbsp;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
3) richiesta
risarcimento danni. (regolato da 1492).&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
La prima viene chiamata azione redibitoria: rimborso prezzo pagato
e spese sostenute. A volte non si può chiedere la risoluzione se vi sono gli
usi che lo escludono. La scelta di una delle due è irrevocabile dopo la domanda
giudiziale. Se la cosa è perita per i vizi, si può chiedere risoluzione del
contratto. Se è perita per i vizi, si può chiedere la risoluzione del
contratto.&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
Se è perita per caso fortuito o per colpa del compratore, vi
è solo l’azione estimatoria. Nel caso la cosa non sia perita, il compratore
deve restituire la cosa dopo il risarcimento.&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
In ogni caso, il venditore è tenuto verso il compratore al
risarcimento del danno a meno che non provi che non conosceva i vizi.&lt;/div&gt;

&lt;div class=&quot;MsoNormal&quot;&gt;
&lt;span style=&quot;font-family: Arial;&quot;&gt;Abbiamo visto il monopolio e
la concorrenza perfetta. Fra i due estremi vi sono altre forme di mercato che
ora andremo ad accennare.&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
&lt;span style=&quot;font-family: Arial;&quot;&gt;OLIGOPOLIO&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
&lt;span style=&quot;font-family: Arial;&quot;&gt;Le caratteristiche
principali dell’oligopolio sono:&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;ul style=&quot;margin-top: 0cm;&quot; type=&quot;disc&quot;&gt;
&lt;li class=&quot;MsoNormal&quot; style=&quot;mso-list: l0 level1 lfo1; tab-stops: list 36.0pt;&quot;&gt;&lt;span style=&quot;font-family: Arial;&quot;&gt;Pochi produttori&lt;/span&gt;&lt;/li&gt;
&lt;li class=&quot;MsoNormal&quot; style=&quot;mso-list: l0 level1 lfo1; tab-stops: list 36.0pt;&quot;&gt;&lt;span style=&quot;font-family: Arial;&quot;&gt;Forte interdipendenza tra le imprese&lt;/span&gt;&lt;/li&gt;
&lt;li class=&quot;MsoNormal&quot; style=&quot;mso-list: l0 level1 lfo1; tab-stops: list 36.0pt;&quot;&gt;&lt;span style=&quot;font-family: Arial;&quot;&gt;Competizione basata su: innovazione, pubblicità,
     servizi&lt;/span&gt;&lt;/li&gt;
&lt;/ul&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
&lt;span style=&quot;font-family: Arial;&quot;&gt;CONCORRENZA MONOPOLISTICA&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
&lt;span style=&quot;font-family: Arial;&quot;&gt;Si basa sulla
differenzazione dei prodotti: un’azienda può produrre un prodotto della stessa
categoria ma differente.&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
&lt;span style=&quot;font-family: Arial;&quot;&gt;Ad esempio: Apple produce
l’Iphone. Nessuno può produrre uno smartphone uguale (per viadei marchi di
fabbrica), quindi Apple ha un potere di monopolio sull’Iphone. I competitors
(Samsung) dovranno quindi sviluppare un prodotto simile, differenziandolo nella
forma, caratteristiche, applicazioni etc etc.&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
&lt;span style=&quot;font-family: Arial;&quot;&gt;Le caratteristiche principali
della concorrenza monopolistica quindi sono:&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;ul style=&quot;margin-top: 0cm;&quot; type=&quot;disc&quot;&gt;
&lt;li class=&quot;MsoNormal&quot; style=&quot;mso-list: l1 level1 lfo2; tab-stops: list 36.0pt;&quot;&gt;&lt;span style=&quot;font-family: Arial;&quot;&gt;Offerta atomistica&lt;/span&gt;&lt;/li&gt;
&lt;li class=&quot;MsoNormal&quot; style=&quot;mso-list: l1 level1 lfo2; tab-stops: list 36.0pt;&quot;&gt;&lt;span style=&quot;font-family: Arial;&quot;&gt;Sostituibilità del prodotto è minore della
     concorrenza&lt;/span&gt;&lt;/li&gt;
&lt;li class=&quot;MsoNormal&quot; style=&quot;mso-list: l1 level1 lfo2; tab-stops: list 36.0pt;&quot;&gt;&lt;span style=&quot;font-family: Arial;&quot;&gt;Elevata differenziazione&lt;/span&gt;&lt;/li&gt;
&lt;/ul&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
&lt;span style=&quot;font-family: Arial;&quot;&gt;Oligopolio e concorrenza
monopolistica sono in ogni caso abbastanza simili fra loro.&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
&lt;span style=&quot;font-family: Arial;&quot;&gt;MONOPOLIO NATURALE&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
&lt;span style=&quot;font-family: Arial;&quot;&gt;I rendimenti di scala sono
crescenti, ovvero i costi di produzione diminuiscono se aumenta la scala. Il
problema è che per entrare nel mercato sono necessarie ingenti quantità di
denaro, quindi di fatto non ci sarà mai nessuno disposto a spendere tali somme.
In questo caso siamo di fronte a ciò che viene definito un Monopolio Naturale
(pensiamo a FS, Enel, l’acqua, i trasporti pubblici nelle città etc).&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
&lt;span style=&quot;font-family: Arial;&quot;&gt;Sorge però un problema:&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;ul style=&quot;margin-top: 0cm;&quot; type=&quot;disc&quot;&gt;
&lt;li class=&quot;MsoNormal&quot; style=&quot;mso-list: l2 level1 lfo3; tab-stops: list 36.0pt;&quot;&gt;&lt;span style=&quot;font-family: Arial;&quot;&gt;Se l’azienda pone P = MC la q* è efficiente ma
     non copre i costi fissi&lt;/span&gt;&lt;/li&gt;
&lt;li class=&quot;MsoNormal&quot; style=&quot;mso-list: l2 level1 lfo3; tab-stops: list 36.0pt;&quot;&gt;&lt;span style=&quot;font-family: Arial;&quot;&gt;Se l’azienda pone P = AC la q non è efficiente
     ma copre i costi fissi&lt;/span&gt;&lt;/li&gt;
&lt;/ul&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
&lt;span style=&quot;font-family: Arial;&quot;&gt;La soluzione è tenere P = MC
e i costi non coperti vengono sussidiati dal comune (provincia, regione,
stato).&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
&lt;br /&gt;&lt;/div&gt;

&lt;br /&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
&lt;span style=&quot;font-family: Arial;&quot;&gt;I ricavi sono r = py.
Calcolando il differenziale rispetto a y avremo che:&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
&lt;span style=&quot;font-family: Arial;&quot;&gt;∂r/∂y = 1p + y(∂p/∂y) ovvero
∂r/∂y =&lt;span style=&quot;mso-spacerun: yes;&quot;&gt;&amp;nbsp;&amp;nbsp; &lt;/span&gt;p[1 + (y/p)(∂p/∂y)] &lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
&lt;span style=&quot;font-family: Arial;&quot;&gt;Essendo poi ε(y) =
(p/y)(∂y/∂p), ovvero 1/ε(y) = (y/p)(∂p/∂y), si ha:&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
&lt;span style=&quot;font-family: Arial;&quot;&gt;∂r/∂y = p [1 + 1/ε(y)]&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
&lt;span style=&quot;font-family: Arial;&quot;&gt;Ricordo che la
massimizzazione del profitto in regime di Monopolio è: RM = MC quindi p [1 +
1/ε(y)] = MC.&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
&lt;span style=&quot;font-family: Arial;&quot;&gt;Se notate, quando
l’elasticità tende ad infinito (quindi 1/ε(y) tende a zero) MC = P (prezzo),
ovvero è dimostrata l’equivalenza della massimizzazione del profitto in regime
di Concorrenza.&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
&lt;span style=&quot;font-family: Arial;&quot;&gt;Sviluppando p [1 + 1/ε(y)] =
MC si arriva, in pochi semplici passaggi, alla forma:&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
&lt;span style=&quot;font-family: Arial;&quot;&gt;P – MC = -P/ε(y) ovvero
(P-MC)/P = - 1/ε(y) = L&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
&lt;span style=&quot;font-family: Arial;&quot;&gt;Questo è l’Indice di Lerner,
il quale indica il potere di mercato di un’impresa.&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
&lt;span style=&quot;font-family: Arial;&quot;&gt;Considerando che ε(y) per
definizione è sempre negativa, abbiamo che: &lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
&lt;span style=&quot;font-family: Arial;&quot;&gt;P [1 - 1/|ε(y)|] = MC ovvero
P = MC/(1-1/|ε(y)|). La quantità fra parentesi è definita Mark Up.&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
&lt;span style=&quot;font-family: Arial;&quot;&gt;Il prezzo nel Monopolio è un
Mark Up sul costo marginale MC.&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;

&lt;div class=&quot;MsoNormal&quot;&gt;
&lt;span style=&quot;font-family: Arial;&quot;&gt;Abbiamo parlato dello schema
SCP, in cui P (performance) è rappresentata dai profitti π. I mercati sono
mossi dal profitto. Come già detto, per i neoclassici lo scopo è massimizzare π
nel mercato.&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
&lt;span style=&quot;font-family: Arial;&quot;&gt;Il mercato è il luogo ideale
in cui si scambia la stessa merce.&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
&lt;span style=&quot;font-family: Arial;&quot;&gt;le caratteristiche
principali del mercato concorrenziale sono:&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
&lt;br /&gt;&lt;/div&gt;

&lt;li class=&quot;MsoNormal&quot; style=&quot;mso-list: l0 level1 lfo1; tab-stops: list 36.0pt;&quot;&gt;&lt;span style=&quot;font-family: Arial;&quot;&gt;Scopo è massimizzare il profitto&lt;/span&gt;&lt;/li&gt;
&lt;/ul&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
&lt;span style=&quot;font-family: Arial;&quot;&gt;π = R – C (Ricavi – Costi)&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
&lt;span style=&quot;font-family: Arial;&quot;&gt;la quale si può scrivere
anche come: p x q – (Φ(q) – F)&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
&lt;span style=&quot;font-family: Arial;&quot;&gt;Vi sono due condizioni per
massimizzare il profitto:&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
&lt;span style=&quot;font-family: Arial;&quot;&gt;1) Condizione di primo
ordine&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
&lt;span style=&quot;font-family: Arial;&quot;&gt;∂π/∂q = p – Φ’(q) = 0 &lt;/span&gt;--&amp;gt;&lt;span style=&quot;font-family: Arial;&quot;&gt; p = Φ’(q) ovvero il prezzo deve essere uguale al
costo marginale&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
&lt;span style=&quot;font-family: Arial;&quot;&gt;2) Condizione di secondo
ordine&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
&lt;span style=&quot;font-family: Arial;&quot;&gt;∂’π/∂’q = ∂’C/∂’(q) =
-Φ(q)&lt;0 span=&quot;span&quot;&gt;--&amp;gt;&lt;span style=&quot;font-family: Arial;&quot;&gt;
Φ(q)&amp;gt;0 ovvero il costo marginale è crescente&lt;/span&gt;&lt;!--0--&gt;&lt;/0&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
&lt;span style=&quot;font-family: Arial;&quot;&gt;CONSIDERAZIONI PIU&#39; GENERALI:&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
&lt;span style=&quot;font-family: Arial;&quot;&gt;Secondo i neoclassici la
massimizzazione di π si basa sulla Razionalità Assoluta. A quel tempo le
imprese erano piccole. Con l’avvento della rivoluzione, nascono le grandi
imprese, ove proprietà e gestione sono divise (azionisti e managers). Nasce
quindi la Teoria Comportamentistica,
la quale si basa sulla Razionalità Limitata e sul Comportamento Soddisfacente
(è razionale dati i vincoli ambientali ed organizzativi.&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
&lt;span style=&quot;font-family: Arial;&quot;&gt;Si sviluppano poi altre
teorie e modelli:&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
&lt;span style=&quot;font-family: Arial;&quot;&gt;Teoria di Bauner: l’impresa
punta a massimizzare le vendite&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
&lt;span style=&quot;font-family: Arial;&quot;&gt;Modello di Marris: l’impresa
punta alla massimizzazione del saggio di crescita bilanciato&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
&lt;span style=&quot;font-family: Arial;&quot;&gt;Modello di Williamson: i
managers massimizzano la loro funzione di utilità (sicurezza posto di lavoro,
stipendio, prestigio)&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
